EngineThe engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine: gasoline (also called a spark-ignition engine) and diesel (also called a compression-ignition engine). Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the transmissionAll engines have fuel, exhaust, cooling, and lubrication systems. Gasoline engines also have an ignition system. The ignition system supplies the electric spark needed to ignite the air-fuel mixture in the cylinders. When the ignition switch is turned on, current flows from the 12-volt storage battery to the ignition coil. The coil boosts the voltage to produce the strong spark of 20,000 V needed to ignite the engine fuel.The automobile supplies all the electricity it needs through its electrical system. For example, the electrical system supplies electricity for the ignition, horn, lights, heater, and starter. The electricity level is maintained by a charging circuit.The fuel system stores liquid fuel and delivers it to the engine. The fuel is stored in the tank, which is connected to a fuel pump by a fuel line.The cooling system removes excessive heat from the engine. The temperature in engine combustion chambers is about 2,000℉( 1,094℃). Since steel melts at around 2,500℉(1,354℃), this heat must be carried away to prevent engine damage. Air and a coolant are used to carry away the heat. The radiator is filled with a coolant. The water pump circulates this coolant through the hollow walls of the engine block and head. Constant circulation of the coolant through the engine and the radiator removes heat from the engine.Heat also is removed by the radiator fan, which draws air through the narrow fins of the radiator. This system also supplies heat to the passenger compartment and the window defrosters.The lubrication system is important in keeping the engine running smoothly. Motor oil is the lubricant used in the system. The lubrication system has four functions:1. It cuts down friction by coating moving parts with oil.2. It produces a seal between the piston rings and the cylinder walls.3. It carries away sludge, dirt, and acids.4. It cools the engine by circulating the motor oil.To keep this system working efficiently, oil filters and motor oil must be changed regularly.The automotive engine is essentially a heat engine. The heat engines used in automobiles are internal combustion engines.1. Principle of OperationThe spark-ignition engine is an internal-combustion engine with externally supplied in ignition. The gasoline engine is a kind of spark-ignition engines.The four-stroke-cycle gasoline engine cycle is spread over four piston strokes. The operation strokes areThe first stroke in your engine is called the intake stroke. Instead of opening the intake valve after you have drawn the piston down, you will find it better to open the intake valve as the piston starts down [1]. This allows the air to draw fuel in the entire time the piston is moving down. Remember, the intake stroke starts with the piston at the top of the cylinder (intake valve open and exhaust valve closed) and stops with the piston at the bottom of its travel [2]. This requires one-half turn ofthe crankshaftAs the crankshaft continues to move, the piston is forced up through the cylinder. If you keep both valves closed, the fuel mixture will be squeezed, or compressed, as the piston reaches the top. This is called the compression stroke. It, too, requires a half turn of the crankshaft.The compression stroke serves to break up the fuel into even smaller particles. This happens due to the sudden swirling and churning of the mixture as it is compressed.When the air-fuel mixture is subjected to a sudden sharp compression force, its temperature rises. This increase in temperature makes the mixture easier to ignite and causes it to explode with greater force. As the piston reaches the top of its travel on the compression stroke, it has returned to the proper position to be pushed back down by the explosion.Remember, the compression stroke starts with the piston at the bottom of the cylinder (both valves closed) and stops with the piston at the top of the cylinder. This requires an additional half turn of the crankshaft.As the piston reaches the top of the compression stroke, the mixture is broken into tiny particles and heated up. When ignited, it will explode with great force. This is the right time to explode the mixture. A spark plug provides a spark inside the combustion chamber. The spark produced at the plug is formed by the ignition system.Just imagine that a hot spark has been provided in the fuel mixture. The mixture will explode and, in turn, force the piston down into the cylinder. This gives the crankshaft a quick and forceful push. This is the power stroke. Both valves must be kept closed during the power stroke or the pressure of the burning fuel will squirt out through the valve pods. Remember, the power stroke starts with the piston at the top of the cylinder (both valves closed) and stops with the piston at the bottom of the cylinder. This requires another half turn of the crankshaft.When the piston reaches the bottom of the power stroke, the exhaust valve opens. The spinning crankshaft forces the piston up through the cylinder, pushing burned gases out. This is the exhaust stroke.Remember, the exhaust stroke starts with the piston at the bottom of the cylinder (exhaust valve open and intake valve closed). It stops with the piston at the top of the cylinder. This requires one more half turn of the crankshaft.If you count the number of half turns in the intake, compression, power, and exhaust strokes, you will find you have a total of four. This gives you two complete turns, or revolutions, of the crankshaft. While the crankshaft is turning around twice, it is receiving power only during one half turn, or one fourth of the time.Each complete cycle consists of four strokes of the piston, hence the name four-stroke cycle.2. Main Engine Components1)Engine blockThe engine block serves as a rigid metal foundation for all parts of an engine. It contains the cylinders and supports the crankshaft and camshaft. In older engines, the valve seats, ports, and guides are built into the block. Accessory units and the clutch housing are bolted to it.Blocks are made of either cast iron or aluminum. The lighter the block (providing it has sufficient strength), the better. The modern thin-wall casting process controls core size and placement much more accurately than the older casting process. This permits casting the block walls much thinner, reducing the weight of the block. Since the block wall thickness is more uniform, block distortion during service is less severe.2)cylinderThe cylinder is a round hole formed in the block. It forms a guide for the piston and acts as a container for taking in, compressing, firing, and exhausting the air-fuel charge. Cylinders have been made of both steel and cast iron. Cast iron is by far the most popular.When steel cylinders are desired in an aluminum block, they are installed in the form of cylinder sleeves (round, pipe-like liners), These sleeves may be either cast or pressed into the block. Some engines use removable cylinder sleeves. When the cylinder becomes worn, the old sleeves can be pulled out and new sleeves can be pressed in. The sleeves are pressed into oversize cylinder holes. Cylinder sleeves are widely used in heavy-duty truck and industrial engines. Sleeves can also be used to repair a worn or cracked cylinder in a cast iron block.3)PistonsThe piston must move down through the cylinder to produce a vacuum to draw a fuel charge into the cylinder. It then travels up in the cylinder and compresses the mixture. When the mixture is fired, the pressure of the expanding gas is transmitted to the top of the piston. This drives the piston back down through the cylinder with great force, transmitting the energy of the expanding gas to the crankshaft. The piston then travels up through the cylinder and exhausts the burned fuel charge.Pistons are usually made of aluminum. Often, aluminum pistons are tin-plated to allow proper break-in when the engine is started. Aluminum pistons can be forged, but they are more commonly cast. Cast iron is a good material for pistons used in a slow-speed engine. It has excellent wear characteristics and will provide good performance.4)Connecting RodsAs the name implies, connecting rods are used to connect pistons to the crankshaft. The upper end of the rod oscillates (swings back and forth), while the lower, or big end, bearing rotates (turns).Because there is very little bearing movement in the upper end, the bearing area can be reasonably small. The lower end rotates very fast, and the crankshaft bearing journal turns inside the connecting rod. This rotational speed tends to produce heat and wear. To make the rod wear well, a larger bearing area is required.The upper end of the rod has a hole through it for the piston pin. The bottom of the large end of the connecting rod must be removed so the rod can be installed on the crankshaft journal. The section that is removed is called the connecting rod cap.Connecting rods are normally made of alloy steel. They are drop-forged to shape and then machined.5)CrankshaftThe engine crankshaft provides a constant turning force to the wheels. It has throws to which connecting rods are attached, and its function is to change the reciprocating motion of the piston to a rotary motion to drive the wheels. Crankshafts are made of alloy steel or cast iron.The crankshaft is held in position by a series of main bearings. The maximum number of main bearings for a crankshaft is one more than the number of cylinders. It may have fewer main bearings than cylinders. Most engines use precision insert bearings that are constructed like the connecting rod bearings, but are somewhat larger. In addition to supporting the crankshaft, one of the main bearings must control the forward and backward movement.6)flywheelA heavy flywheel is attached to the rear of the crankshaft with bolts. The function of the flywheel is to smooth out engine speed and keep the crankshaft spinning between power strokes, in some engines, the flywheel also serves as a mounting surface for the clutch. The outer rim of the flywheel has a large ring attached with gear teeth cut into it. The teeth of the starter motor engage these teeth and spin the flywheel to crank the engine. When an automatic transmission is used, the torque converter assembly works with the flywheel.7)CamshaftThe camshaft is used to open and close the valves. There is one cam on the camshaft for each valve in the engine. Generally only one camshaft is used in most engines. Newer engines are increasingly equipped with two or more camshafts8)ValvesEach engine cylinder ordinarily has two valves. However, modern engines often use four valves per cylinder (two intake and two exhaust). A few engines used in smaller vehicles have three or five valves per cylinder: two intake valves and one exhaust valve or three intake valves and two exhaust valves.Because the head of an exhaust valve operates at temperatures up to 1300℉(704℃), valves are made of heat-resistant metal. In order to prevent burning, the valve must give off heat to the valve seat and to the valve guide. The valve must make good contact with the seat and must run with minimum clearance in the guide.9)Valve LiftersMechanical valve lifters are usually made of cast iron. The bottom part that contacts the camshaft is hardened. Some lifters are hollow to reduce weight. Most valve trains that contain mechanical lifters have some provision for adjusting clearance. Mechanical valve lifters were used in older engines.Hydraulic valve lifters perform the same job as mechanical lifters. However, hydraulic lifters are self-adjusting, operate with no lifter-to-rocker arm clearance, and uses engine oil under pressure to operate. Hydraulic lifters are quiet in operation.3. Engine Classification1)Cycle ClassificationEngines are often classified according to cycle. Most internal combustion piston engines use a two- or four-stroke cycle. All modern automobile engines use the four-stroke cycle engine.The two-stroke cycle engine performs the intake, compression, firing, and exhaust sequence in one revolution of the crankshaft.Cylinder ClassificationThe inline engine has its cylinders arranged one after the other in a straight line. They are in a vertical, or near vertical position. Most modern inline engines are four cylinders.A V-type engine places two banks or rows of cylinders at an angle to each other—generally at 60°or 90°. The V-type engine has several advantages: short length, extra block rigidity, a short, heavy crankshaft, and low profile that is conducive to low hood lines. The shorter block permits a reduction in vehicle length with no sacrifice in 2)passenger room.The horizontal opposed engine is like a V-type engine, except that both banks lie in a horizontal plane. The advantage here is an extremely low overall height, which makes this engine ideally suited to installations where space is limited.Cooling ClassificationAs you have learned, engines are either liquid-cooled or air-cooled. Most vehicles use liquid-cooled engines. Air-cooled engines are used in limited numbers on modern vehicles.3)Fuel ClassificationAutomobile engines can use gasoline, diesel fuel, gasohol (mixture of gasoline and alcohol), alcohol, LNG (liquefied natural gas), CNG (compressed natural gas), or LPG (liquefied propane gas). Gasoline powers the majority of vehicles, but diesel fuel is used in some vehicles. Gasohol, LNG, CNG, and LPG are beginning to see wider use. One of the principal differences in these engines is in method of fuel delivery and carburetion. Gasoline, LNG, CNG, and LPG utilize the same basic type of engine, but LNG, CNG, and LPG utilize a slightly different fuel delivery setup. Diesel engines do not use a carburetor or an ignition system.1.发动机发动机是汽车的动力装置。

发动机英文翻译(EngineEnglishtranslation)
发动机英文翻译(Engine English translation)The engineThe mechanism that converts internal energy into kinetic energy is called the engine, and the engine is mainly in the form of cylinders and pistons as the internal combustion engine of the converter. Depending on the fuel and the type of ignition, it can be divided into a gasoline engine or diesel engine, or an engine with hydrogen, natural gas, and oil and gas as fuel, and its combustion form is less different from that of gasoline engines. According to the work cycle and piston stroke characteristics, it can be divided into two stroke and four stroke engines.EngineTo be able to translate into kinetic energy of the body known as the engine, car engine is the main form of the cylinder and piston of internal combustion engine as a conversion mechanism. According to the fuel and ignition forms can be divided into different gasoline engine or a diesel engine, or hydrogen, natural gas, petroleum gas as fuel to the engine, the gasoline engine combustion form and smaller differences. According to the working cycle and piston stroke characteristics, and can be divided into two stroke and four stroke engine,A four-stroke engine cylinder, piston, piston, connecting rod, crankshaft, distribution agencies (valve, camshaft, etc.), the spark plug (gasoline engine), nozzle in cylinder (diesel engine, as well as with direct injection technology of gasoline engine in cylinder), oil pump and oil circulation, water pump and watercycle, and a series of sensors and ECU many parts.Four stroke engine main cylinder, piston, piston connecting rod, crankshaft, valve (valve, CAM shaft), a spark plug (gasoline engine), in-cylinder fuel injector, oil pump and oil circulation, water pump and water circulation, another series of sensors and ECU and many other components.The construction and working principle of internal combustion engineThe structure and working principle of internal combustion engineThe working chamber of reciprocating piston type internal combustion engine is called cylinder, and the inner surface of the cylinder is cylindrical. The piston of reciprocating motion in the cylinder is hinged by the piston pin and the connecting rod, and the other end of the connecting rod is connected to the crankshaft, which forms the crank connecting rod mechanism. Therefore, when the piston is reciprocating in the cylinder, the connecting rod pushes the crankshaft to rotate, or vice versa. At the same time, the volume of the working chamber is constantly changing from the smallest to the largest, then the largest to the smallest, and so on. The top of the cylinder is closed with a cylinder cover. The intake and exhaust doors are mounted on the head of the cylinder head, and the intake and exhaust valve is mounted upside down to the top of the cylinder. Through the opening and closing of the inlet and exhaust doors, the air cylinder can be filled up and out of the cylinder.The opening and closing of the exhaust door is controlled by camshaft. The camshaft is driven by the crankshaft through the toothed belt or gear or chain. The inlet, exhaust valve and camshaft and other components form the gas distribution mechanism. This structure is usually described as a gas distribution mechanism with a roof valve. The modern internal combustion engine adopts the roof valve distribution mechanism without exception. The parts that make up the cylinder are called the cylinder block, and the part of the supporting crankshaft is called the crankcase, and the cylinder body and the crankcase are called the body.Reciprocating piston internal combustion engine working chamber called the cylinder, the inner surface of the cylinder. In the cylinder for reciprocating motion of the piston through the piston pin and one end of the connecting rod is hinged, the other end of the connecting rod is connected with the crankshaft, form the crank connecting bar mechanism. Therefore, when the piston in the cylinder for reciprocating motion, the connecting rod drives the crankshaft to rotate, or the opposite. At the same time, a working chamber volume is also constantly from the smallest to the largest, again by the maximum to minimum, so the cycle. The top end of the cylinder by cylinder lid closure. The cover of the cylinder is provided with the inlet valve and exhaust valve, intake, exhaust valve head down tail up upside down in the cylinder top. Through the inlet, exhaust valve opening and closing to within the cylinder to cylinder exhaust gas and. Inlet, exhaust valve opening and closing is controlled by a camshaft. Cam shaft by the crankshaft via a toothed belt or a gear or chain drive. Inlet, exhaust valve and the cam shaft and other parts composed of gas distribution mechanism. Oftencalled the structural form of the gas distribution mechanism for overhead valve mechanism. Modern car engines are invariably uses overhead valve mechanism. To form the cylinder parts called cylinder body, supporting the crankshaft parts called the crankcase, cylinder block and crankcase casting body known as the body.The working principle ofThe working principle of a four-stroke gasoline engineThe four-stroke reciprocating piston internal combustion engine completes the four processes of intake, compression, work and exhaust during the four piston trips, namely, only one process is carried out in one piston stroke. As a result,The piston stroke can be named after four processes.1. Air intake strokeThe piston moves from the top to the bottom of the crankshaft. The exhaust valve closes and the intake valve opens. During the movement of the piston, the cylinder volume gradually increases and a certain vacuum degree is formed in the cylinder. The mixture of air and gasoline is inhaled through the intake valve and further mixed into a combustible mixture in the cylinder.2. The compression strokeAt the end of the intake stroke, the crankshaft continues todrive the piston from the bottom to the top stop. The inlet and exhaust doors are closed. As the piston moves, the cylinder volume decreases, and the mixture in the cylinder is compressed, and its pressure and temperature rise simultaneously.3. Work tripAt the end of the compression stroke, the spark plug that is installed on the cylinder head generates an electric spark, which ignite the combustible mixture in the cylinder. The flame quickly travels through the combustion chamber, releasing a lot of heat energy. The volume of combustion gas expands rapidly, and the pressure and temperature rise rapidly. Under the action of the gas pressure, the piston is moved from the top to the bottom, and the crankshaft rotates to work through the connecting rod. The inlet and exhaust doors are still closed.4. The exhaust strokeExhaust stroke, the exhaust valve opens, the inlet valve is still closed, the crankshaft by connecting rod drives the piston by the next check point moves to the first check point, the combustion gas after the expansion at this time (or gas) on residual stress and its own under the impetus of the piston, through the exhaust discharge outside the cylinder. When the piston reaches the upper stop, the exhaust stroke ends and the exhaust gate closes.The Working principleOne, four stroke gasoline engine working principleFour stroke reciprocating piston internal combustion engine in the Four piston travel to complete the intake, compression will power, and exhaust Four the processes, i.e. for a piston in travel only a process.

All the automotive engines today are the Internal Combustion Engines ( ICEs ) because the fuel is burnt inside their cylinders and the energy is provided.ICEs are those heat engines that burn their fuel inside the engine cylinder. In ICEs, the chemical energy stored in their fuel converted into heat energy during the burning part of their operation. The heat energy is converted into mechanical energy by the expansion of gases against the piston attached to crankshaft that can rotate. The engines that burn petrol are known as petrol engine. Other types of ICEs burn heavier oils, of these types the diesel engine has come into the widest use.Diesel and petrol engines have the same mechanical parts, except that diesel components are generally stronger and heavier. Both engines are internal combustion engines, but they have different fuel system and use different fuels. With a diesel, only air enters the cylinder during the intake stroke. A petrol engine takes in an air-fuel mixture. Following are some general comparisons between diesel and petrol engines: In a diesel, the fuel is injected into the cylinder as a fine spray near the top of the compression stroke. With a petrol engine, the fuel is injected into the exhaust ports at the start of the induction stroke.Ignition in a diesel is by the high temperature from the highly compressed air. A petrol engine needs a spark for ignition.Diesel engines generally operate at lower engine rpm than petrol engines.Diesel engines use distillate for fuel, which is less volatile than petrol.The design of diesel engines makes them noisier than petrol engines and they have a unique diesel knock.Small diesel engines, as well as petrol engines, are used in passenger cars and light commercial vehicles. Larger diesel engines are used in all heavy commercial vehicles, earthmoving equipment, and farm machinery.1.Engine ConfigurationsThe term engine configuration refers to the way that the cylinders of an engine are arranged. The cylinders can be in-line, or at an angle ( V-type ). Within these three basic arrangements, there are a number of variations.In-line engineWith in-line engines, the cylinders are arranged in a straight line, one behind the other. Most in-line engines have their cylinders vertical, but some are slanted. That is, the engine is tilted at an angle to reduce the overall height. These engines are sometimes referred to as slanted engines.Some in-line engines have their cylinders horizontal, so that the engine is more or less on its side. This reduces the overall height of the engine. This arrangement is <插图位置>used mainly in larger commercial vehicles with the engine mounted under part of the cab. The mechanical arrangement of a four-cylinder in-line for a passenger car is shown in Fig.1-9. The cut-away view in Fig.1-10 enables the various parts to be identified.Horizontally opposed engineThis arrangement has its cylinders arranged in two flat blanks with the crankshaft between them. The engine shown has a short rigid crankshaft with five bearings. A horizontally opposed engine has even firing impulses and good balance. Movement of a piston in direction is opposed by movement of a piston in the opposite direction.Horizontally opposed engines, with their flat design, give the engine a low height and also help to keep the center of gravity of the vehicle low. A low center of gravity gives the vehicle stability.V-type enginesWith V-type engines, the cylinders are arranged in two blanks at an angle. This reduces the length of the engine and makes it more compact. This also reduces the length of the crankshaft, which can be designed to be more rigid than a long shaft. 2.The Engine Assembly and ComponentsThe complete engine assembly consists of the mechanical components that make up the engine itself and also a number of associated systems. These are the systems that are needed to start the engine and also to control it and keep it running. The mechanical parts of the engine assembly can be broken down into a number of sub-assemblies, or groups of associated components, although these are usually referred to merely as assemblies, for example, cylinder-head assembly and piston assembly. Some parts of an engine are internal, other parts are external, this illustration identifies a number of external parts.The various components of an engine are assembled together during manufactured and most of these are secured by means of bolts, nuts and other types of fasteners. Some parts are internal and others are attached to the outside of the engine.The cylinder block is the largest part of engine. The other parts are either fitted into the block or attached to it. As its name suggests, it is basically a block of castmetal, usually cast iron, but it can be aluminum alloy with cast iron or steel liners. Aluminum is used to reduce the weight.The cylinder block has accurately bored cylinders to take the pistons. The lower part of the block is known as the crankcase and this has bearings that carry the crankshaft. The water-jackets that surround the cylinders are filled with coolant.The top of the cylinder block has a machined surface for the cylinder head and the bottom of the cylinder block is machined to provide a mounting for the oil pan, or sump.The cylinders can be arranged in the block so that they are in line, as shown, or they can be set at angle ( V-type engine ).The crankshaft is mounted in bearings in the lower part of the cylinder block ( the crankcase ). The connecting rods connect the pistons to the crankshaft, which is rotated by the power strokes of the pistons when the engine is running. The up-and-down, or reciprocating, motion of the pistons is changed to rotary motion by the combination action of the connecting rods and the cranks of the crankshaft.The term crankshaft comes from the word cranked, which also means bent. It is a shaft with a number of cranks or bends. With in-line engines, there a crank for each cylinder, but with some V-type engines, there is only one crank for each pair of cylinders.The flywheel is a heavy cast iron wheel attached to the rear of the crankshaft. It reduces engine vibrations by smoothing out the power impulses of the pistons. The flywheel absorbs energy during the power stroke and gives up energy during the other strokes and this helps to keep the engine running smoothly. A ring gear fitted to the rim of the flywheel so that the engine can be rotated by the starter pinion when starting the engine. With automatic transmissions, a drive plate and torque converter take the place of the flywheel and perform the same functions as a flywheel, as far as the running of the engine is concerned.The piston has grooves that carry the piston rings and these provide a seal between the piston and the cylinder wall. Compression rings are used as a gas seal and the oil ring is used to prevent excess oil from finding its way up past the piston into the combustion chamber.The connecting rod has a removable cap and a split bearing at its lower end where it is connected to the crankshaft. Its upper has a piston pin that provides a wrist-type of action with the piston. Because of its action, the piston pin is sometimes referred to as a wrist pin.The cylinder head is made of cast aluminum alloy. It is bolted to the top of the cylinder block so that it encloses the cylinders. It has combustion chambers above the cylinders in which the air-fuel mixture is burnt. Cylinder heads can be made of cast iron, which is more resistant to corrosion, but aluminum alloy is used for petrol engines because it has advantages of better heat transfer and lighter weight. The cylinder head has intake ports and exhaust ports. The intake valves open the intake ports to admit the fuel charge into the cylinder during the intake stroke. The exhaust valves open the exhaust ports to allow the burnt gases to leave the cylinder following the exhaust stroke.The camshaft and the valve mechanism are used to open and close the valves at the correct time. The camshaft is driven from the crankshaft at half the crankshaft speed.The valve cover, also called the cylinder-head cover, is fitted to the top of the cylinder head. This encloses the valve mechanism. An additional cover on top of the engine covers the ignition coils.This cylinder-head arrangement, for a four-cylinder engine, has two camshafts and sixteen valves. Other four-cylinder engines can have two camshafts and twelve valves, or one camshaft and eight valves.The timing belt and pulleys drive the camshaft at half the crankshaft speed ( engine speed ). A toothed drive belt is often used, but gears and chains are also used-in some instances a belt and chain are both used.On some engines, the timing chain is used to drive the oil pump. On diesel engines, a timing chain or a timing gear is used to drive the injection pump as well as the camshaft.The oil pan, or sump, holds the oil for the engine lubricating system. The oil pan is made of steel that has been pressed to shape. Other oil pans are made of aluminum alloy that has been cast to shape.The oil pan is bolted to the underside of the engine so that it closes off the crankcase. Only the ends of the crankshaft that extend beyond the cylinder block are exposed.Various forms of gaskets and seals are used between the surfaces where the parts are bolted together. Some of these are used to seal against oil, some against coolant and some against heat and pressure. Some provide a seal on flat surfaces, other seal against rotating shafts.As well as the larger parts of an engine, there are numerous small parts. These include bolts, washers, retainers, spring and brackets which go to make up the mechanical components of the engine.3.Engine SystemsThe engine systems that enable the engine to start and to continue to operate are as follows:(1)Starting system;(2)Fuel system;(3)Ignition system;(4)Cooling system;(5)Lubricating system;(6)Intake system;(7)Exhaust system;(8)Charging system;(9)Engine’s electronic control system.These are the systems for petrol engines. Diesel engines have similar systems except for the fuel and ignition systems. Some parts of the systems are built into theengine, some parts are attached to the engine and other parts are located on the body panels in the engine compartment.Starting systemThe starter is used to rotate the engine during starting. It consists of an electric motor and a drive. The drive has a small pinion that meshes with the ring gear on the flywheel during starting. The battery supplies the electrical energy to operate the starter and rotate the engine until it fires and runs on its own.Fuel systemThese are four basic types of fuel systems: carburetor systems for petrol engines, fuel injection systems for petrol engines, gas fuel systems ( LPG or NGV ), and diesel injection systems. All these systems operate in different ways, but they all have somewhere to store fuel ( a fuel tank or a cylinder ) and a way of supplying the engine with the fuel. They also have a way of supplying air and fuel mixed in the correct proportion so that it can be effectively burn in the combustion chambers.Ignition systemPetrol engines and engines operating on gas require an ignition system. This is needed to provide the sparks that fire the charges in the combustion chambers. For this reason, petrol engines are sometimes referred to as spark-ignition engines. This distinguishes them from them diesel engines that do not need a spark because they use compression ignition.Combustion in a diesel occurs when the fuel is sprayed into the combustion chamber. The air in the cylinder is at high temperature from being compressed-high enough to ignite the fuel that is sprayed from the injector.Cooling systemA considerable amount of heat is produced in an engine by the burning air-fuel mixture. Some of the heat is used to do useful work, some is transferred to other parts of the engine and some is carried away with exhaust gases. However, there is still enough heat to cause damage unless it is removed. This is still the function of the cooling system, which removes about one-third of the heat that is produced.The cooling system does not just remove heat; it maintains the engine at a desirable operating temperature. In a liquid-cooled engine, this is done by circulating coolant through the water-jackets. In an air-cooled engine, cooling is by air over cooling fins.Lubricating systemThe engine-lubricating system consists of an oil pump, a relief valve and a filter; also pipes, passages and drillings in various parts of engine through which the oil can flow. A quantity of oil is held in the oil pan. From this, oil is taken by the oil pump and circulated throughout the engine before returning to the oil pan. The oil lubricates all the moving parts and this is not only reduces friction, but it prevents wear anddamage. The oil pump is driven directly by the crankshaft. This system has an oil cooler, located at the filter mounting under the filter.Intake systemIn petrol engine with electronic fuel injection, the intake system includes the air cleaner, the throttle valve assembly and the intake manifold. The intake system provides clean air and carries it into the engine through the intake manifold. Nozzles of the fuel injectors spray fuel into the air passing from the intake manifold into the intake ports.With carburetor fuel systems, a mixture of air and fuel is carried from the carburetor, through the intake manifold and into the engine through the intake ports.For engines that operate on gas, a mixture of air and gas is carried into the engine by the intake manifold.In petrol engines with fuel injection, and in diesel engines, clean air only is provided by the intake system.Exhaust systemThe exhaust system carries the burnt gases away from the engine and also reduces noise. The system consists of the exhaust manifold, exhaust pipes, a catalytic converter and a muffler. Arrangements vary with different engines, there may be more than one muffler and more than one catalytic converter. Engines that run on Lead Replacement Petrol ( LRP ) do not have a catalytic converter, neither do diesel engines.Charging systemThe alternator, which is driven by the engine, converts mechanical energy to electrical energy.The battery supplies energy for the starter, the ignition system and electric fuel pump during the starting period ( petrol engine ), but once the engine is running, the alternator supplies all the electrical energy. It also recharges the battery to replace the energy used during starting.Engine’s electronic control systemThe engine’s electronic control system consists of sensors, a control unit and actuators. The control unit receives signals from the sensors and then sends signals to various actuators.There are sensors on the engine, in the intake system and in the exhaust system. The injectors are actuators that adjust the spray of fuel. There are also actuators in the ignition system that advance and retard the spark. These are just two examples of where electronic control is used.4.Engine OperationDuring the downward motion of the piston, the air-fuel mixture is sucked fromthe carburetor into the cylinder. During the upward motion the mixture is compressed by the piston in the cylinder and ignited by an electric spark. When the mixture is burned in the cylinder, the resulting heat causes the gases to expand which exert pressure on the cylinder walls and on the piston. The piston, being movable, is pushed downward by this pressure to the full length of its stroke.The pressure exerted on the piston is transmitted through the connecting rod to the crankshaft that is made to revolve. The crankshaft turns through one-half of a revolution as the piston moves downward. A flywheel attached to the crankshaft stores up energy. The momentum of the flywheel carries the piston through the balance of its motion until it receives another power impulse. The process is repeated over and over again, the crankshaft is turning continuously and the engine is running.The events that are repeated make up the cycle of the engine. The number of stokes of the piston required to complete the cycle varies with the type of engine. In modern vehicles, the cycle is extended through four stroke of the piston or two revolutions of the crankshaft. This is called a four-stroke cycle engine. In two stroke cycle engines, the cycle is completed in two strokes of the piston or one revolution of the crankshaft.In the four-stroke cycle engine, the four strokes are named suction, compression, power, and exhaust in accordance with the operation of the cycle which occur during each particular stroke.Suction stroke: during suction stroke, the piston is moved downward by the crankshaft, which is revolved either by the momentum of the flywheel or by the power generated by the electric starting motor. The inlet valve remains open and the exhaust valve is closed during this stroke. The downward movement of the piston sucks air-fuel mixture in the cylinder from the carburetor through the open inlet valve. Here the fuel is petrol mixed with air, broken up into a mist, and partially vaporized in the carburetor.Compression stroke: during compression stroke, the piston moves upward, thus compressing the charge. Ignition and much of the compression also take place during this stroke. The heat produced by the compression makes more homogeneous mixture of air and petrol inside the cylinder. The heat makes the petrol easier to burn, while the compression forces it into closer combination with the air. The mixture, under compression, is ignited by the spark produced by a spark plug, and the combustion is over half-completed when the piston is at Top Dead-Centre ( TDC ). Both the inlet and exhaust valves remain closed during the compression stroke.Working, power or expansion stroke: the expansion of the gases due to the heat of combustion exerts a pressure on the cylinder and piston. Under this impulse the piston moves downward thus doing useful work. Both the valves remain closed during this stroke.Exhaust stroke: during this stroke, the inlet valve remains closed and the exhaust valve opens. The greater part of the burnt gases escapes because of their own expansion. The piston moves upward and pushes the remaining gases out of the open exhaust valve. Only a small quantity of exhaust gases remains in the clearance space which will dilute the fresh incoming charge.Thus, in this type of engine, four strokes of the piston are required to complete the cycle, and the four strokes make two revolutions of the crankshaft. The operations are repeated over and over again in running the engine.发动机的组成发动机是汽车的重要组成部分,它为汽车提供行驶的动力,对汽车而言它就像心脏对人一样重要。

Motor vehicle suspension on the vehicle suspension system is a very important system. Not only does it affect the comfort of the car (ride), but also to other properties such as the adoption, as well as the stability of the attachment have a significant impact on performance, each of the suspension by the elastic components (buffers), body-oriented (from Chuan And stabilizing role), as well as shock absorbers (from the role of shock absorption). However, not all of the suspension must have three components. As long as we can play to the role of the three.Vehicle maintenance for the conservation network 1, flying the classification1. Non-independent suspension: on both sides of the wheel mounted ona total-vehicle-bridge, the train-bridge to fly through the frame and connected. This suspension structure is simple and reliable power-but by two rounds of shock and vibration affecting each other. But also because of the quality of flying non-serious suspension of the poor performance of the buffer, the vibration of a moving car, the greater the impact. The suspension generally used for trucks, buses and a number of other ordinary vehicles. (2) independent suspension: each individual through a set of wheels mounted on the body or suspension of vehicular bridge, the use of off-Axle, in the middle of a fixed frame or body; such wheel on both sides of the suspension by the shock Hubuyingxiang, but due to non-flying than by the quality; buffer with a strong shock absorption capacity, ride comfort. The indicators are better than non-independent suspension, but the complex structure of the suspension, but it also drive axle, steering system has become complicated. The use of such suspension of the following two categories of vehicles. Cars, buses and passenger vehicles. Can be improved ride comfort, and high speed when driving the car to improve stability.Off-road vehicles, military vehicles and mining vehicles. In a bad way and have no say under the circumstances, we can make sure all the wheels on the ground and contacts to enhance stability and driving the car attached, to play a speed of the car.2.Flexible yuan for the type of (1) of the leaf spring: the long-range multi-chip and curvature ranging from the composite plate. After installed at both ends of the natural upward curve. In addition to the leaf spring with a buffer, there is a certain degree of shock absorption, vertical layout also has a force-oriented, non-independent suspension using most of the leaf spring so flexible components, save-oriented devices and shock absorbers, simple structure . (2) of the coil spring: only a cushion for the multi-car independent suspension. In the absence of damping force and mass functions must also be equipped with special shock absorbers and device-oriented. (3) oil and gas spring: a flexible medium as a gas, liquid as a medium-power, which not only has a good buffer capacity, also has a role in shock absorption and at the same time frame of a high degree of regulation may also be applicable to the use of heavy vehicles and buses. (4), torsion bar springs; will be made under the torsion bar springs fixed at one end of the frame, on the other side through the arm and connected to the wheels, and beat at wheel torsion bar the use of reverse deformation played the role of buffer, is suitable for independent The use of suspension.3. the use of shock absorber tube shock absorbers, the use of oil in the small role to cut energy consumption vibration. Shock absorber and the upper body frame or connected with the lower end of the train-bridge connected. Most of the trip can be done and the compression of the dual role of the role of shock absorber.4.device-oriented: the flexibility in the independent suspension components, most of them can only transfer the vertical loads and can not transmit vertical and horizontal, must be a separate device-oriented. As noted, under the arm and vertical, horizontal stabilizer, and so on.5. non-independent suspension: before and after the truckswere non-independent suspension bridge, some vehicles such as buses and cars and so on, after the bridge is also a non-independent suspension. Each car of the sedan chair by hoisting two independent non-vertical arrangement of the composition of the leaf spring. Leaf spring fixed in the middle of the train-bridge, with the front end hinged frame or body, the back-end with the frame or body through the ear hanging hinged or connected to use of skateboards. Top of the frame with a shock absorber then, with the lower end of the next school Axle. The truck rear axle and more without shock absorbers.6. many types of independent suspension, coil spring as the use of flexible components. Torsion bar springs for the independent suspension is also divided into vertical and horizontal torsion torque Cup two-under. Although many of the advantages of an independent suspension, but the car would turn the system, the Department of driving and driving more complicated structure of the bridge.Keywords: structure of the engine engine performance merits of a direct impact on the performance of motor vehicles.First, the use of fuel by the different categories according to engine fuel, gasoline engine and the engine is divided into two major categories of diesel engines.1 .network Motor conservation maintenance, gasoline engine small size, light weight, low prices; good start, when the maximum power ofhigh-speed;work in a small vibration and noise; suitable for small and medium-sized car in particular, the use of high-speed car.Gasoline deflagration due to the restrictions can not be too high compression ratio, thermal efficiency and economy are not, such as diesel. Gasoline is a mixture of the main gas pipeline in the form over into the cylinder, compressed by the end of close to the spark plugs fire. The driver to speed up the adoption of the control pedal into the cylinder of the gas mixture to control the load on the engine, known as the volume of regulation. Gasoline engine’s fuel supply system and ignition system is a gasoline engine failure on the part of a higher proportion. Gasoline engine emissions of harmful material composition of carbon monoxide, carbon compounds and nitrogen oxides than diesel, and so on, but with the current electronically controlled fuel injection system and other exhaust gas purification devices, which have greatly improved. In addition, the gasoline engine’s torque characteristics are very suitable for automotive use, can significantly reduce the labor intensity of the driver.2. diesel and gasoline engine, diesel engine size, weight, high prices, poor start (especially when the low temperature); work more vibration and noise; easy to overload when the black smoke. Diesel is characterized by:1) the absence of the deflagration, as well as restrictions on the needs of the spontaneous combustion of diesel, diesel engine compression ratio high. Thermal efficiency and economy must be better than the gasoline engine.2) the same power, the diesel engine’s torque, maximum power at the time of low speed, suitable for the use of the truck.3) is a mixture of diesel engine cylinder internal form, no inlet throttle, the intake of small resistance. The driver to speed up the adoption of fuel injection control board, to change the engine load, known as the regulation of quality, as there is no problem of hypoxia, emissions of hydrocarbons and carbon monoxide content of less than gasoline.4) In the absence of the ignition system, as well as fuel supply device failure rate low. Therefore, failure to less than diesel gasoline engine.5) diesel engine torque characteristics are not suitable for car driving cycle needs, moving the stalls to use frequently, an increase of pilot labor intensity. The main diesel engine for use in medium and heavy vehicles.Second, the number of engine cylinder and arrangement of the engine cylinder displacement equal to the volume of work and.Increase in the number of cylinder engine will not only increase capacity, improve the engine output power, but also to enable the smooth operation of the engine to reduce noise and vibration. Hyundai Motor have adopted multi-cylinder engine. Mini-car for more than 3-cylinder engine, small trucks, passenger cars and medium-sized following for more than 4-cylinder engine; medium-sized trucks, large cars and buses for more than 6-cylinder engine; Heavy-Duty Truck General of 6-8 cylinder. 6-cylinderengine under a single row multi-cylinder in-line mode; 8-cylinder V-type engines for alignment; some of the cars in order to reduce engine height, length shortened, using V6, V8-type arrangement. Mini-car use of3-cylinder engine, most oblique way. In-line engine structure is simple and cheap. The disadvantage is that a high degree of the engine higher longer length.Is more a way. V-type engines with low height, short length, but the structure of the complex, more expensive price, suitable for large-scale engine. Water-cooled engine block using the whole cast. Small engines used aluminum alloy materials, large-scale multi-engine for the cast iron. Cylinder head bolts used in a fixed block on the plane, in addition to constitute a closed cylinder combustion room, into the exhaust, valves are installed, and spark plug valve, and so on.Third, the gasoline engine’s fuel supply 1, the fuel-supply system carburetor gasoline engine fuel supply line into carburetor andfuel-injection two major categories of carburetor main oil installations operating principle is:the work of the engine when the outside air In the cylinder under the suction air filter to filter through into the cylinder. When the air flow through the pipe section due to the smaller increase in the velocity and pressure led to the decline in a certain vacuum. Float on the interior of gasoline in the vacuum from the role of the main inlet into the spray nozzle, the gas emitted by high-speed air currents disperse into mist, known as fogging. And then to oil and oil-film evaporation space in the form of evaporation, and the airway had mixed into the air mixture into the cylinder. In order to achieve the economy, the main oil loading also uses the air brake. The main nozzle at the indoor air, and along with a few scheduled to open around the through-hole and air the same room. When the throttle opening gradually increases, the air hole graduallyconnected with the air. Not only reduces the vacuum so that the mixture-thinning, the main air nozzle is also beneficial to the atomization of gasoline. 2. electronically controlled fuel injection fuel-supply system carburetor fuel-supply device structure is simple, reliable, cheap, easy maintenance. But the biggest drawback is that it can not be precisely controlled mixture of concentration, resulting in incomplete combustion, emissions of harmful ingredients, do not meet the stringent requirements of environmental protection today. In addition, due to the existence of the pipe so that the air resistance increases. There is also the cylinder uneven distribution of gasoline and easy to produce and Qizu ice and so on. In order to solve these problems, 80 electronically controlled fuel injection system in the car engine on a wide range of applications more and more.electronically controlled fuel injection system advantages: electronically controlled fuel injection system (referred to as English EFI) has the following advantages:1. no matter under what conditions and in what conditions the engine can accurately control the mixture of concentration, To make gasoline burn completely full. This greatly reduces the emission of harmful components of content, also has an excellent combustion engine of the economy.2. can supply, ignition temperature, such as centralized control, so that the work of the engine performance, increased engine power output, lower fuel consumption.3. the engine can always operate in a stable condition in a variety of conditions so that all car drivers in accordance with the requirements of normal traffic.4. In the absence of pipes, a small air resistance. At the same time, difficult to produce Qizu, to the distribution of gas cylinder uniform, and so on. The shortcomings of the fuel injection system is the high cost structure of the complex and difficult to repair, and so on.electronically controlled fuel injection system of classification:1) by way of testing the air quality into the way traffic density and speed of the way the two categories.2) by way of fuel injection, the following two categories. According to the location of the jet, into intake manifold junction (SPI) and the jet intake manifold Department (MPI) are two jet, respectively, also known as single-point and multi-point injection jet.MPI is currently widely used in the way. Department of gasoline ignition gasoline engine ignition system are generally three categories: contact-type ignition system, electronic ignition system,computer-controlled ignition system.车辆悬架系统中的机动车辆悬架系统是一种非常重要的系统。

【机械类文献翻译】发动机的分类和总体结构
外文翻译1 Engine Classification and Overall MechanicsThe automobile engines can be classified according to :1.number of cylinders ;2.arrangement of cylinders ;3.arrangement of valves ;4.type of cooling ;5.number of cycles (two or four );6.type of fuel burned ;7.type of ignition .The engine is the source of power that makes the wheels go around and the car move .the automobile engine is an internal-combustion engine because the fuel (gasoline ) is burned inside it .the burning of gasoline inside the engine produces high pressure in the engine combustion chamber .this high pressure in the engine combustion chamber .this high pressure forces piston to move ,the movement is carried by connecting rods to the engine crankshaft .the crankshaft is thus made to rotate ;the rotary motion is carried through the power train to the car wheels so that they rotate and the car moves .The engine requires a fuel system to supply it with a mixture of air and fuel .the fuel system does this by pumping liquid gasoline from tank into the carburetor a mixing device that mixes the gasoline with air .the mixture is delivered to engine where it is burned.The engine also needs a cooling system, the combustion of the air-fuel mixture in the engine creates a very high temperature (as high as 2000 to 2700 C).the cooling system take heat away from the engine by circulating a liquid coolant (water mixed with antifreeze ) between the engine and a radiator .the coolant gets hot as it goes through the engine .it cools off as it goes through the radiator. Thus ,the coolant continually takes heat away from the engine ,where it could do damage ,and delivers it to the radiator. Air passing though the radiator takes heat away from the radiator.The engine also includes a lubricating system. The purpose of the lubricating system is to supply all moving parts inside the engine with lubricating oil ;the oil keeps moving parts from wearing excessively .The engine requires a fourth system ,the ignition system. The ignition system provides high-voltage electric sparks that ignite, or set fire to ,the charges of air-fuel mixture in the engine combustion chambers.The fifth is starting system and its purpose is to change the electrical current into the mechanical energy to push the crank-shaft around. By means of this ,the engine can be started.2 Four –stage –engine OperationThe action taking place in the engine cylinder can be divided into four stages ,or strokes. Store refers to piston movement ;a stroke occurs when the piston moves from one limiting position to the other. The upper limit of piston movement is called TDC (top dead center ). The lower limit of piston movement is called BDC (bottom dead center ). A stroke is piston movement from TDC to BDC or from BDC to TDC. In other words ,the piston completes a stroke each time it changes its direction of motion .Where the entire of events in the cylinder requires four strokes (or two crankshaft revolution ),the engine is called a four-stroke-cycle engine ,or a four-cycle engine. The four piston strokes are intake ,compression power ,and exhaust .Intake stroke. On the intake stroke ,the intake valve has opened ,the piston is moving downward ,and a mixture of air and vaporized gasoline is entering the cylinder through the valve port. The mixture of air and vaporized gasoline is delivered to the cylinder by the fuel system and carburetor .Compression stroke. After the piston reaches BDC ,or the lower limit of its travel ,it begins to move upward. As this happens ,the intake valve closes. The exhaust valve is also closed ,so that the cylinder is sealed. as the piston moves upward (pushed now by the revolving crankshaft and connecting rod ),the air-fuel mixture is compressed. By the time the piston reaches TDC ,the mixture has been compressed to as little as one-tenth of its original volume ,or even less. This compression of the air-fuel mixture increases the pressure in the cylinder. When the air-fuel mixture is compressed ,not only does the pressure in the cylinder go up ,but the temperature of the mixture alsoincreases .Power stroke. As the piston reaches TDC on the compression stroke ,an electric spark is produced at the spark plug. The ignition system delivers a high-voltage surge of electricity to the spark plug to produce the spark.. The spark ignites, or air-fuel mixture. It now begins to burn very rapidly ,and the cylinder pressure increases to as much as 3-5MPa or even more. This terrific push against the piston forces it downward ,and a power impulse is transmitted through the connecting rod to the crankpin on the crankshaft .the crankshaft is rotated as the piston is pushed down by the pressure above it .Exhaust stroke. As the piston reaches BDC again ,the exhaust valve opens. Now ,as the piston moves up on the exhaust stroke ,it forces the burned gases out of the cylinder through the exhaust-valve port. Then ,when the piston reaches TDC ,the exhaust valve closes and the intake valve opens. Now a fresh charge of air-fuel mixture will be drawn into the cylinder as the piston moves down again toward BDC. The above four strokes are continuously repeated.3 Two –stage-engine OperationIn the four-stroke-cycle engine ,already discussed in Lesson 1,2,the complete cycle of events requires four piston strokes (intake ,compression ,power and exhaust ). In the two-stroke-cycle ,or two-cycle ,engine ,the intake and compression strokes and the power and exhaust strokes are in a sense combined. This permits the engine to produce a power stroke every two piston strokes ,of every crankshaft rotation .In the two-cycle engine ,the piston acts as a valve ,clearing valve ports in the cylinder wall as it nears BDC .A fresh air-fuel charge enters through the intake port ,and the burned gases exit through the exhaust port. The complete cycle of operation is as follows: as the piston nears TDC, ignition takes place. The high combustion pressures drive the piston down ,and the trust through the connecting rod turns the crankshaft. As the piston nears BDC, it passes the intake and exhaust ports in the cylinder wall. Burned gases ,still under some pressure ,begin to streamout through the exhaust port. At the same time ,the intake port ,now cleared by the piston ,begins to deliver air -fuel mixture ,under pressure to the cylinder. The top of the piston is shaped to give the incoming mixture an upward movement. This helps to sweep the burned gases ahead and out through the exhaust port.After the piston has passed through BDC and starts up again ,it passes both ports ,thus sealing them off. Now the fresh air-fuel charge above the piston is compressed and ignited. The same series of events takes place again and continue as long as the engine runs.We mentioned that the air-fuel mixture is delivered to the cylinder under pressure. In most engines, this pressure is put on the mixture in the crankcase. The crankcase is sealed except for a leaf ,or reed ,valve at the bottom. The reed valve is a flexible flat metal plate that rests snugly against the floor of the crankcase. There are holes under the reed valve that connect to the engine carburetor. When the piston is moving up , a partial vacuum is produced in the sealed crankcase. Atmospheric pressure lifts the reed valve off the holes ,and air-fuel mixture enters the crankcase. After the piston passes TDC and starts down again , pressure begins to build up in the crankcase. This pressure closes the reed valve so that further downward movement of the piston compresses the trapped air-fuel mixture in the crankcase. The pressure which is built up on the air-fuel mixture then causes it to flow up through the intake port into the engine cylinder when the piston moves d own far enough to clear the intake port.The two-stroke engine is not only very simple but gives nearly twice the power of a four stroke engine from a cylinder of given size, but it is wasteful of gasoline, as some mixture inevitably finds its way into the exhaust system on the combines intake /exhaust stroke , and there are always some combustion products left in the cylinder which reduce the rapid burning of the fuel. This kind of engine is always used in motorcycles.4 Engine Cylinder Block Crankcasewe have seen how the mixture of air and fuel is delivered by the fuelsystem to the engine cylinder ,where it is compressed ,ignited ,and burned. We have noted that this combustion produces a high pressure that pushes the piston down so that t he crankshaft is rotated. Now let us examine the various parts of the engine in detail .Engine cylinder block.The cylinder block of liquid-cooled engines forms the basic framework of the engine. Other parts are attached to the cylinder block or are assembled in it. The block is cast in one piece from gray iron or iron alloyed with other metals ,such as nickel or chromium. Some blocks are cast from aluminum. The block contains not only the cylinders but also the water jackets that surround them. In aluminum blocks ,cast-iron of steel cylinder sleeves (also called bore liners ) are used. There metals have better wearing qualities than aluminum and can better withstand the wearing effect of the pistons and rings moving up and down in the cylinders. For most engines ,cast iron has been found to be a satisfactory cylinder-wall material. However , in some small engines ,the cylinder walls are plated with chromium ,a very hard metal ,to reduce wall wear and lengthen their life .Cylinder Head.The cylinder head is usually cast in one piece from iron , from iron alloyed with other metals , or from aluminum alloy. Aluminum has the advantage of combining head tends to run cooler , other factors being equal. There are two types of head ,L head and I head. Cylinder head contains water jackets for cooling ; in the assembled engine , cylinder-block water jackets. Spark-plug holes are provided ,along with pockets into which the valves can move as they open .Gaskets.The joint between the cylinder block and the head must be tight and able to withstand the pressure and heat developed in the combustion chambers. The block and head can not be machined flat and smooth enough to provide an adequate seal. Thus , gaskets are used. Head gaskets are made of thin sheets of soft metal or of asbestos and metal. All cylinder , water ,valve ,and head-bolt openings are cut out. When the gasket is placed on the block and the head installed , tightening of the head bolts (or nuts )squeezes the soft metal so that the joint is effectively sealed.Gaskets are also used to seal joints between other parts, such as between the oil pan , manifolds ,or water pump and the block .Oil Pan.The oil pan is usually formed of pressed steel it usually holds 5 to 10 liters of oil , depending on the engine design. The oil pan and the lower part of the cylinder block together are called the crankcase ; they enclose ,or encase ,the crankshaft. The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and runs down into the pan. Thus ,there is constant circulation of oil between the pan and the working parts of the engine.5 Piston Connecting Cod piston.The piston is essentially a cylindrical plug that moves up and down in the engine cylinder. It is equipped with piston rings to provide a good seal between the cylinder wall and piston. The piston absorbs heat from the gas ,and this heat must be carried away if the metal temperature is to be held within safe limits. The constant reversal of the piston travel sets up inertia forces ,which increase both with the weight of the piston and with its speed. For this reason , designers try to keep piston weight low ,particularly in high speed engines. As lower hood lines and over square engines became popular , the semi-slipper and full-slipper pistons was reduced to three ,two compression and one oil-control. One reason for the slipper piston is that ,o the short stroke ,over square engine ,the piston skirt had to be cut away to make room for the counterweights on the crankshaft. Also ,the slipper piston ,being shorter ad having part of its skirt cut away ,is lighter. This reduces the inertia load on the engine bearings and ,in addition ,make for a more responsive engine. The lighter the piston ,the less the bearing load and the longer the bearings will last. Another way to lighten the piston is to make it of light metal. The ideal piston material would be light and strong ,conduct heat well ,expand only slight when heated ,resist wear ,and be low in cost. Thus most automotive-en gibe pistons today are made of aluminum ,which is less that half as heavy as iron. Iron pitons were common in the earlier engines. Aluminum expands more rapidly than iron with increasing temperature ,however more rapidly than iron withincreasing temperature ,however ,and since the cylinder block is of iron ,special provisions must be made to maintain proper piston clearance at operating temperature. To take care of it ,the crown is machined on slight taper ,the diameter being greatest where the crown meets the skirt and becoming less toward the top .Piston. RingsA good seal must be maintained between the piston and cylinder wall to prevent blow-by. Blow-by is the name that describes the escape of burned gases from the combustion chamber ,past the piston ,and into the crankcase. In other words ,these gases blow by the piston. It is not practical to fit the piston to the cylinder closely enough to prevent blow-by. Thus ,piston rigs must be used to provide the necessary seal. The ring are installed in grooves in the piston. Actually ,there are two type of rings ,compression rings and oil-control rings. The compression rings seal in the air-fuel mixture as it is compressed and also the combustion pressures as the mixture burns. The oil-control rings scrape off excessive oil excessive oil from the cylinder wall and return it to the oil pan .The ring have joints (they are split )so that they can be expanded and slipped over the piston head and into the recessed grooves cut in the piston. Rings for automotive engines usually have butt joints, but in some heavy-duty engines, the joints may be angled ,lapped ,or of the sealed type.The rings are somewhat larger in diameter than they will be when in the cylinder. then ,when they are installed, they are compressed so that the joints are nearly closed. Compressing the rings rives them an initial tension ;they press tightly against the cylinder wall.Connecting Rod .The connecting rod is attached at one end to a crankpin on the crankshaft and at other end to a piston, through a piston pin or wrist pin. the connecting rod must be very strong and rigid and also as light as possible. the connecting rod carries the power thrusts from the piston to the crankpin. At the same time ,the rod is in eccentric motion. To minimize vibration and bearing loads ,the rod must be light in weight. To maintain good engine balance ,connecting rods and caps are carefully matched in sets for engines. All rods in an engine must be of equal weight ; if theyare not ,noticeable vibration may result. In original assembly ,rods and caps are individually matched to each other and usually carry identifying numbers so they will not be mixed if the engine is disassembled for service. They must not be mixed during any service job ,since this could result in poor bearing fit and bearing failure.6 TireTire have two functions. First ,they interpose a cushion between the road and the car wheels to absorb shocks resulting from irregularities in the road. The tire flex ,or give ,as bumps are encountered ,thus reducing the shock effect to the passengers in the car. Second ,the tires provide frictional contact between the wheels and the road so that good traction is secured. This permits the transmitting of power through the tire to the road for rapid accelerating ,combats the tendency of the car to skid on turns ,and allows quick stops when the brakes are applied.Tire ate of two basic types ,solid and pneumatic (air-filled ). Solid tires have very limited usage ,being confined largely to specialized industrial applications. Pneumatic tires are of two types ,those using an inner tube and the tubeless type. The amount of air pressure used depends on the type of tire and operation. Passenger-car tire inflated to about 275to 413k Pa. Air is introduced into the tire (or inner tube ) through a valve that opens when the chuck on the air hose if applied. On the tire with an inner tube ,the valve is mounted on the tube. On the tubeless tire ,the valve is mounted on the wheel rim.7 Steering SystemThe purpose of the steering system is guiding the car where the driver wants it to go It consists of steering wheel ,steering ,shaft ,worm ,gear ,sector ,pitmanarm ,drag link ,steering knuckle arm ,king pin steering knuckle arm ,kingpin ,steering arms ,tie rod ,front axle and steering knuckle . they enable the car to change the direction by means of turning and moving forth and back.Actually ,the steering system is composed of two elements ,a steering gear at the lower end of the steering column and linkage between thee gear and the wheel steering knuckles. The steering system permits the front wheels to be pivoted on their supports to the right or left so that rue car can be steered. This movement isproduced by gearing and linkage between the steering wheel in front of the driver and the steering knuckle (or wheel ).The steering gear is a device for converting the rotary motion of the steering wheel into straight-line motion (of linkage ). Essentially ,the steering gear consists of two parts ,a worm on the end of the steering shaft and a pitman arm shaft on which there is a gear sector ,toothed roller ,or stud. The gear sector ,toothed roller ,or stud meshes with the worm.Many types of steering linkage have been made to connect between the steering knuckles of the font wheels and the pitman arm of the steering gear. The pitman arm swings from one side to the other ( or forward and backward on some cars ) as the steering wheel is turned. This movement must be carried to the steering knuckles at thee wheels by some form of linkage. All have some means of adjusting the lengths of the tie rods or links so that proper alignment can be established between the front wheels. This alignment gives the front wheels a slight toe-in when the car begins to move forward ,this toe-in practically disappears as all looseness ,or slippage ,in the steering system is taken up .The steering wheel is mounted on a steering shaft that extends into the steering gear. The bottom end of the shaft has a worm gear that rotates as the wheel is turned. A gear sector is meshed with the worm gear ; rotation of the worm gear causes the gear sector to rotate. This movement causes the pitman arm , attached to the sector ,to swing to the right or left .this action, in turn ,pushes or pulls on the tie rods attached to the pitman arm. The steering-knuckle arm ,attached to the front wheels ,are therefore forced to swing the wheel to the right or left on their pivots.There are two general types of power steering. One type is self-contained ,with all hydraulic pressure applied to the pitman arm shaft. The other type uses a standard type gearbox with a power cylinder attached to the linkage system. The self-contained type is currently in widespread usage. Both kinds of power steering systems are actuated by oil pressure. The pressurized oil is admitted to either side of the power cylinder as controlled by a valuing setup. Oil pressure is provided by a high pressure oil pump that ,generally is belt driven by the engine.1发动机的分类和总体结构汽车发动机可以按以下几种情况分类:1、按气缸的数量分类;2。

汽车发动机外文文献翻译(含:英文原文及中文译文)文献出处:Talom M. AUTOMOTIVE ENGINE[J]. Applied Thermal Engineering, 2013, 2(3):39-45.英文原文AUTOMOTIVE ENGINETalom M1 Engine Classification and Overall MechanicsThe automobile engines can be classified according to: (1) cycles, (2) cooling system, (3) fuel system, (4) ignition method, (5) valve arrangement, (6) cylinder arrangement, (7) engine speed.Engines used in automobiles are the internal combustion heat engines. The burning of gasoline inside the engine produces high pressure in the engine combustion chamber. This high pressure force piston to move, the movement is carried by connecting rods to the engine crankshaft. The crankshaft is thus made to rotate: the rotary motion is carried through the power train to the car wheels so that they rotate and the car moves.The engine requires four basic systems to run (Fig. 2-1). Diesel engines require three of these systems. They are fuel system, ignition system (except diesel), lubricating system andcooling system. However, three other related systems are also necessary. These are the exhaust system, the emission-control system, and the starting system. Each performs a basic job in making the engine run.2 Engine Operating PrinciplesThe term “stroke” is used to desc ribe the movement of the piston within the cylinder. The movement of the piston from its uppermost position (TDC, top dead center) to its lowest position (BDC, bottom dead center) is called a stroke. The operating cycle may require either two or four strokes to complete. Most automobile engines operate on the four stroke cycle.In four-stroke engine, four strokes of the piston in the cylinder are required to complete one full operating cycle. Each stroke is named after the action. It performs intake, compression, power, and exhaust in that order.The intake strokeThe intake stroke begins with the piston near the top of its travel. As the piston begins its descent, the exhaust valve closes fully, the intake valve opens and the volume of the combustion chamber begins to increase, creating a vacuum. As the piston descends, an air/fuel mixture is drawn from the carburetor into the cylinder through the intake manifold. The intake stroke endswith the intake valve close just after the piston has begun its upstroke.Compression strokeAs the piston is moved up by the crankshaft from BDC, the intake valve closes. The air/fuel mixture is trapped in the cylinder above the piston. Future piston travel compresses the air/fuel mixture to approximately one-eighth of its original volume (approximately 8:1 compression ratio) when the piston has reached TDC. This completes the compression stroke. Power strokeAs the piston reaches TDC on the compression stroke, an electric spark is produced at the spark plug. The ignition system delivers a high-voltage surge of electricity to the spark plug to produce the spark. The spark ignites, or sets fire to, the air/fuel mixture. It now begins to burn very rapidly, and the cylinder pressure increases to as much as 3-5MPa or even more. This terrific push against the piston forces it downward, and a powerful impulse is transmitted through the connecting rod to the crankpin on the crankshaft. The crankshaft is rotated as the piston is pushed down by the pressure above it.Exhaust strokeAt the end of the power stroke the camshaft opens theexhaust valve, and the exhaust stroke begins. Remaining pressure in the cylinder, and upward movement of the piston, force the exhaust gases out of the cylinder. At the end of the exhaust stroke, the exhaust valve closes and the intake valve opens, repeating the entire cycle of events over and over again.3 Engine Block and Cylinder HeadEngine BlockThe engine block is the basic frame of the engine. All other engine parts either fit inside it or fasten to it. It holds the cylinders, water jackets and oil galleries (Fig. 2-4). The engine block also holds the crankshaft, which fastens to the bottom of the block. The camshaft also fits in the block, except on overhead-cam engines. In most cars, this block is made of gray iron, or an alloy (mixture) of gray iron and other metals, such as nickel or chromium. Engine blocks are castings.Some engine blocks, especially those in smaller cars, are made of cast aluminum. This metal is much lighter than iron. However, iron wears better than aluminum. Therefore, the cylinders in most aluminum engines are lined with iron or steel sleeves. These sleeves are called cylinder sleeves. Some engine blocks are made entirely of aluminum.Cylinder SleevesCylinder sleeves are used in engine blocks to provide a hard wearing material for pistons and piston rings. The block can be made of one kind of iron that is light and easy to cast while the sleeves uses another that is better able to stand up wear and tear.There are two main types of sleeves: dry and wet (Fig. 2-5).Dry sleeve Wet sleeveCylinder HeadThe cylinder head fastens to the top of the block, just as a roof fits over a house. The underside forms the combustion chamber with the top of the piston. In-line engine of light vehicles have just one cylinder head for all cylinders; larger in-line engines can have two or more. Just as with engine blocks, cylinder heads can be made of cast iron or aluminum alloy. The cylinder head carries the valves, valve springs and the rockers on the rocker shaft, this part of valve gear being worked by the pushrods. Sometimes the camshaft is fitted directly into the cylinder head and operates on the valves without rockers. This is called an overhead camshaft arrangement.GasketThe cylinder head is attached to the block with high-tensile steel studs. The joint between the block and the head must begas-tight so that none of the burning mixture can escape. This is achieved by using cylinder head gasket. Gaskets are also used to seal joins between the other parts, such as between the oil pan, manifolds, or water pump and the blocks.Oil PanThe oil pan is usually formed of pressed steel. The oil pan and the lower part of cylinder block together are called the crankcase; they enclose, or encase, the crankshaft. The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and run down into the pan. Thus, there is a constant circulation of oil between the pan and the working parts of the engine.4 Piston Assembly, piston rings, The piston pin ,Connecting Rods, Crankshafts And FlywheelPistonPiston rings and the piston pin are together called the piston assembly.The piston is an important part of a four-stroke cycle engine. Most pistons are made from cast aluminum. The piston, through the connecting rod, transfers to the crankshaft the force created by the burning fuel mixture. This force turns the crankshaft.To withstand the heat of the combustion chamber, the piston must be strong. It also must be light, since it travels at high speeds as it moves up and down inside the cylinder. The piston is hollow. It is thick at the top where it takes the brunt of the heat and the expansion force. It is thin at the bottom, where there is less heat. The top part of the piston is the head, or crown. The thin part is the skirt. Most pistons have three ring grooves at the top. The sections between the ring grooves are called ring lands.piston ringsPiston rings fit into ring grooves near the top of the piston. In simplest terms, piston rings are thin, circular pieces of metal that fit into grooves in the tops of the pistons. In modern engines, each piston has three rings. (Piston in older engines sometimes had four rings, or even five.) The inside surface of the ring fits in the groove on the piston. The ring's outside surface presses against the cylinder walls. Rings provide the needed seal between the piston and the cylinder walls. That is, only the rings contact the cylinder walls. The top two rings are to keep the gases in the cylinder and are called compression rings. The lower one prevents the oil splashed onto the cylinder bore fro m entering the combustion chamber, and is called an oil ring.The piston pinThe piston pin holds together the piston and the connecting rod. This pin fits into th e piston pin holes and into a hole in the top end of the connecting rod. The top end of t he rod is much smaller than the end that fits on the crankshaft. This small end fits inside the bottom of the piston. The piston pin fits through one side of the piston, through the small end of the rod, and then through the other side of the piston. It holds the rod firmly in place in the center of the piston. Pins are made of high-strength steel and have a hollow center. Many pins are chrome-plated to help them wear better. A piston pin fits into a round hole in the piston. The piston pin joins the piston to the connecting rod. The thick part of the piston that holds the piston pin is the pin boss. Connecting RodsThe connecting rod little end is connected to the piston pin.A bush made from a soft metal, such as bronze, is used for this joint. The lower end of the connecting rod f its the crankshaft journal. This is called the big end. For this big-end bearing, steel-backed lead or tin shell bearings are used. These are the same as those used for the main bearings. The split of the big end is sometimes at an angle, so that it is small enough t o be withdrawn through the cylinder bore. The connecting rod ismade from forged alloy steel.CrankshaftsThe crankshaft is regarded as the “backbone” of the engine (Fig. 2-7). The crankshaft, in conjunction with the connecting rod, converts the reciprocating motion of the piston to the rotary motion needed to drive the vehicle. It is usually made from car-bon steel which is alloyed with a small proportion of nickel. The main bearing journals fit into the cylinder block and the big end journals align with the connecting rods. At the rear end of the crankshaft is attached the flywheel, and at the front end are the driving wheels for the timing gears, fan, cooling water and alternator. The throw of the crankshaft, . the distance between the main journal and the big end centers, controls the length of the stroke. The stroke is double the throw, and the stroke length is the distance that the piston travels from TDC to BDC and vice versa.中文译文汽车发动机Talom M1发动机分类和一般力学(1)循环,(2)冷却系统,(3)燃料系统,(4)点火方法,(5)阀门布置,(6)气缸布置,(7)发动机速度。

3 power stroke
The end of the compression stroke, mounted on the cylinder head of the spark plug to produce the spark, the cylinder and mixed flammable gas ignition, flame spread rapidly through the combustion chamber, and release a lot of heat. Combustion gas and the rapid expansion of the volume, pressure and temperature rise rapidly. Under the action of the air pressure, the piston from TDC to BDC, and through the connecting rod to drive the crankshaft to rotate to work. Then, in, the exhaust valve remains closed. ""
2.压缩Байду номын сангаас程
进气行程结束后,曲轴继续带动活塞由下止点移至上止点。这时,进、排气门均关闭。随着活塞移动,气缸容积不断减小,气缸内的混合气被压缩,其压力和温度同时升高。
3.作功行程
压缩行程结束时,安装在气缸盖上的火花塞产生电火花,将气缸内的可燃混合气点燃,火焰迅速传遍整个燃烧室,同时放出大量的热能。燃烧气体的体积急剧膨胀,压力和温度迅速升高。在气体压力的作用下,活塞由上止点移至下止点,并通过连杆推动曲轴旋转作功。这时,进、排气门仍旧关闭。
Four stroke reciprocating piston internal combustion engine in the four piston travel to complete the intake, compression, power and exhaust four processes, i.e. in a piston travel only a process. Therefore, the stroke of the piston are four processes named.
Reciprocating piston internal combustion engine working chamber called the cylinder, the inner surface of the cylinder. In the cylinder for reciprocating motion of the piston through the piston pin and one end of the connecting rod is hinged, the other end of the connecting rod is connected with the crankshaft, form the crank connecting bar mechanism. Therefore, when the piston in the cylinder for reciprocating motion, the connecting rod drives the crankshaft to rotate, or the opposite. At the same time, a working chamber volume is also constantly from the smallest to the largest, again by the maximum to minimum, so the cycle. The top end of the cylinder by cylinder lid closure. The cover of the cylinder is provided with the inlet valve and exhaust valve, intake, exhaust valve head down tail up upside down in the cylinder top. Through the inlet, exhaust valve opening and closing to within the cylinder to cylinder exhaust gas and. Inlet, exhaust valve opening and closing is controlled by a camshaft. Cam shaft by the crankshaft via a toothed belt or a gear or chain drive. Inlet, exhaust valve and the cam shaft and other parts composed of gas distribution mechanism. Often called the structural form of the gas distribution mechanism for overhead valve mechanism. Modern car engines are invariably uses overhead valve mechanism. To form the cylinder parts called cylinder body, supporting the crankshaft parts called the crankcase, cylinder block and crankcase casting body known as the body.
In 1 the intake stroke
The crankshaft in a piston driven by the TDC to bdc. When closing the exhaust valve, intake valve opening. In the process of moving piston, cylinder volume gradually increases, the cylinder to form certain vacuum degree. The mixture of air and gasoline through the intake valve is sucked into the cylinder, and the cylinder is further mixed to form a combustible mixture. ""

排气行程开始,排气门开启,进气门仍然关闭,曲轴通过连杆带动活塞由下止点移至上止点,此时膨胀过后的燃烧气体(或称废气)在其自身剩余压力和在活塞的推动下,经排气门排出气缸之外。当活塞到达上止点时,排气行程结束,排气门关闭。

工作原理
一、四冲程汽油机工作原理
四冲程往复活塞式内燃机在四个活塞行程内完成进气、压缩、作功和排气等四个过程,即在一个活塞行程内只进行一个过程。因此,活塞行程可分别用四个过程命名。
1.进气行程
活塞在曲轴的带动下由上止点移至下止点。此时排气门关闭,进气门开启。在活塞移动过程中,气缸容积逐渐增大,气缸内形成一定的真空度。空气和汽油的混合物通过进气门被吸入气缸,并在气缸内进一步混合形成可燃混合气。
内燃发动机的构造及工作原理
The structure and working principle of internal combustion engine
往复活塞式内燃机的工作腔称作气缸,气缸内表面为圆柱形。在气缸内作往复运动的活塞通过活塞销与连杆的一端铰接,连杆的另一端则与曲轴相连,构成曲柄连杆机构。因此,当活塞在气缸内作往复运动时,连杆便推动曲轴旋转,或者相反。同时,工作腔的容积也在不断的由最小变到最大,再由最大变到最小,如此循环不已。气缸的顶端用气缸盖封闭。在气缸盖上装有进气门和排气门,进、排气门是头朝下尾朝上倒挂在气缸顶端的。通过进、排气门的开闭实现向气缸内充气和向气缸外排气。进、排气门的开闭由凸轮轴控制。凸轮轴由曲轴通过齿形带或齿轮或链条驱动。进、排气门和凸轮轴以及其他一些零件共同组成配气机构。通常称这种结构形式的配气机构为顶置气门配气机构。现代汽车内燃机无一例外地都采用顶置气门配气机构。构成气缸的零件称作气缸体,支承曲轴的零件称作曲轴箱,气缸体与曲轴箱的连铸体称作机体。
发动机
将内能转化成动能的机构称之为发动机,汽车发动机的形式主要是以气缸和活塞作为转换机构的内燃机。根据燃料以及点火形式的不同可分为汽油机或柴油机,或有以氢气、天然气、石油气为燃料的发动机,其燃烧形式与汽油机差异较小。根据工作循环与活塞冲程特性划分,又可分为两冲程与四冲程发动机,
Engine
2 compression stroke"
After the intake stroke, the crankshaft continues to drive the piston only by the shift of the top dead point. At this time, inlet, exhaust valves are closed. Along with the movement of the piston, the cylinder volume decreases, mixing gas in the cylinder is compressed, its pressure and temperature increase.
