现在的车辆一般都由15000多个分散、独立且相互配合的零部件组成。

这些零部件主要分为四类：车身、发动机、底盘和电气系统。

汽车车身是一个包含窗子、车门、一个发动机罩、一个行李箱盖的金属薄壳。

汽车车身为发动机、乘员和货物提供了保护。

汽车车身的设计还应该保证乘员的安全舒适。

车身的造型（款式）使得汽车看起来漂亮迷人、色彩斑斓、时尚前卫。

轿车车身为封闭式，轿车最多有4个车门，乘员通过车门进出。

另外车身的设计还应考虑行李和货物的存放。

传统的轿车都是硬顶车身。

活顶乘用车（敞篷车）的车顶是软顶，车身设计与普通轿车类似，但只有两个车门。

皮卡一般用来运载货物。

为能承载更大的总质量，皮卡的底盘部件和悬架比轿车更结实。

轻型货车一般是基于普通轿车设计的，或是重新设计使可用载货空间最大化。

用于运输货物的商用车车身必须满足具体要求，例如运输液体的油罐车、运输泥土或散装谷物的自卸车、运输一般货物的平板车或货车。

发动机作为动力设备，常见的类型是内燃机，其原理是通过发动机缸内的液体燃料燃烧而产生能量。

发动机可分为两类：汽油机（点燃式）和柴油机（压燃式），都属于热力发动机。

燃料燃烧产生热量使缸内气体气压上升，从而产生能量，驱动与动力传动系相连接的轴旋转。

发动机的布置即发动机气缸的排列方式。

发动机缸体按直线排列的即直列式，这种布置使得发动机缸体结构简单。

汽车发动机一般为2~6缸，通常气缸是垂直放置的，但气缸数量的增加会导致缸体和曲轴的长度过大，解决问题的措施之一就是采用V型布置，这种布置方式可以使发动机缸体和曲轴长度尺寸更短，从而大大增加刚度。

前置发动机可以纵向布置，能够驱动前轮或后轮。

后置发动机布置在后轮后侧，发动机即可纵向布置又可横向布置，一般只能驱动后轮。

底盘总成是由作为汽车主要运行部分的各系统组成，包括动力传动系、转向系统、悬架和制动系统。

传动系把发动机输出的扭矩传递给驱动轮。

传动系包括离合器（对应机械变速器）或液力变矩器（对应液力自动变速器）、变速器、驱动轴、主减速器、差速器和驱动桥。

更多汽车资料请访问中国汽车技术论坛：CHAPTER 1 AUTOMOTIVE BASICS1.1 Principal ComponentsToday's average car contains more than 15,000 separate, individual parts that must work together. These parts can grouped into four major categories: engine, body, chassis and electrical equipment.1.2 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 transmission.1.3 BodyAn automobile body is a sheet metal shell with windows, doors, a hood, and a trunk deck built into it. It provides a protective covering for the engine, passengers, and cargo. The body is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modern appearance for the vehicle.1.4 ChassisThe chassis is an assembly of those systems that are the major operating part of a vehicle. The chassis includes the transmission, suspension, steering, and brake systems.Transmission systems ― conveys the drive to the wheels. The main components are clutch, gearbox, driveshaft, final drive, and differential.Suspension― absorbs the road shocks.Steering― controls the direction of the movement.Brake― slows down the vehicle.1.5 Electrical EquipmentThe electrical system supplies electricity for the ignition, horn, lights, heater, and starter. The electricity level is maintained by a charging circuit. This circuit consists of the battery, alternator (or generator). The battery stores electricity. The alternator changes the engine's mechanical energy into electrical energy and recharges the battery.New WordsPrincipal component 主要部件category 种类，类型body 车身chassis 底盘layout 布置power unit 动力装置internal combustion engine 内燃机cylinder 汽缸gasoline 汽油spark 火花ignition 点燃，点火diesel 柴油机compression 压缩shaft 轴transmission 传动系sheet metal 金属板shell 外壳hood （发动机）罩trunk deck 行李舱盖cargo 货物styling 样式assembly 总成，装配suspension 悬挂，悬置shock 冲击steering 转向，操纵brake 刹车，制动器clutch 离合器gearbox 变速器driveshaft 传动轴final drive 主减速器，后桥differential 差速器slow down （使）慢下来，减速horn 喇叭starter 起动机charge 充电alternator 交流发电机Review Questions1.List the main parts of an automobile?2.What are the common types of a vehicle according to body styling?3.Which systems does a chassis include and what are the main functions of the chassis?4.Why are suspension systems used on vehicles?CHAPTER2 INTERNAL COMBUSTION ENGINE2.1 principle of operation2.1.1 Engine and powerEngine is used to produce power. The chemical energy in fuel is converted to heat by the burning of the fuel at a controlled rate. This process is called combustion. If engine combustion occurs with the power chamber. ,the engine is called internal combustion engine. If combustion takes place outside the cylinder, the engine is called an external combustion engine.Engine used in automobiles are internal combustion heat engines. Heat energy released in the combustion chamber raises the temperature of the combustion gases with the chamber. Theincrease in gas temperature causes the pressure of the gases to increase. The pressure developed within the combustion chamber is applied to the head of a piston to produce a usable mechanical force, which is then converted into useful mechanical power.2.1.2 Engine TermsLinking the piston by a connecting rod to a crankshaft causes the gas to rotate the shaft through half a turn. The power stroke “uses up” the gas , so means must be provided to expel the burnt gas and recharge the cylinder with a fresh petrol-air mixture :this control of gas movement is the duty of the valves ;an inlet valve allows the new mixture to enter at the right time and an exhaust valve lets out the burnt gas after the gas has done its job. Engine terms are :TDC(Top Dead Center):the position of the crank and piston when the piston is farther away from the crankshaft.BDC(Bottom Dead Center):the position of the crank and piston when the piston is nearest to the crankshaft.Stroke : the distance between BDC and TDC; stroke is controlled by the crankshaft.Bore : the internal diameter of the cylinder.Swept volume : the volume between TDC and BDC.Engine capacity : this is the swept volume of all the cylinder e.g. a four-stroke having a capacity of two liters(2000cm) has a cylinder swept volume of 50cm.Clearance volume: the volume of the space above the piston when it is at TDC. Compression ratio = (swept vol + clearance vol)\(clearance vol)Two-stroke : a power stroke every revolution of the crank.Four-stroke : a power stroke every other revolution of the crank..2.1.3 The Four-stroke Spark-ignition Engine CycleThe spark-ignition engine is an internal-combustion engine with externally supplied in ignition , which converts the energy contained in the fuel to kinetic energy.The cycle of operations is spread over four piston strokes. To complete the full cycle it takestwo revolutions of the crankshaft.The operating strokes are :This stroke introduces a mixture of atomized gasoline and air into the cylinder . The strokestarts when the piston moves downward from a position near the top of the cylinder . As thepiston moves downward, a vacuum, or low-pressure area, is created.During the intake stroke, one of the ports is opened by moving the inlet valve. The exhaustvalve remains tightly closed.Compression strokeAs the piston moves upward to compress the fuel mixture trapped in the cylinder , the valvesare closed tightly. This compression action heats the air/fuel mixture slightly and confines itwithin a small area called the combustion chamber .Power strokeJust before the piston reaches the top of its compression stroke, an electrical spark isintroduced from a spark plug screwed into the cylinder head.The spark ignites the compressed, heated mixture of fuel and air in the combustion chamberto cause rapid burning. The burning fuel produces intense heat that causes rapid expansionof the gases compressed within the cylinder . This pressure forces the piston downward. Thedownward stroke turns the crankshaft with great force.Exhaust strokeJust before the bottom of the power stroke, the exhaust valve opens. This allows the piston,as it moves upward, to push the hot, burned gases out through the open exhaust valve.Then, just before the piston reaches its highest point, the exhaust valve closes and the inletvalve opens. As the piston reaches the highest point in the cylinder , known as TDC, it startsback down again. Thus, one cycle ends and another begins immediately.2.1.4 Engine Overall MechanicsThe engine has hundreds of other parts . The major parts of engine are engine block , engineheads, pistons, connecting rods, crankshaft and valves. The other parts are joined to make systems.These systems are the fuel system, intake system, ignition system, cooling system, lubricationsystem and exhaust system. Each of these systems has a definite function. These systems willdiscussed in detail later.NEW WORDPiston 活塞Connecting rod 连杆Crankshaft 曲轴Power stoke 活塞行程Expel 排出Valve 气阀inlet(intake) valve 进气阀exhaust valve 排气阀term 术语TDC 上止点BDC 下止点Bore 缸径swept volume 有效容积engine capacity 发动机排量clearance volume 余隙容积,燃烧室容积compression ratio 压缩比revolution 旋转,转数every other 每隔一个cycle 循环spread over 分布,遍及intake stroke 进气行程compression stroke 压缩行程knock 敲缸,敲打exhaust stroke 排气行程engine block 发动机缸体lubrication 润滑2.2 Engine Block and Cylinder Head2.2.1 Engine 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. The engine block also holds the crankshaft, which fastens to the bottom of the block. The camshaft also fits inside the block, except on overhead-cam engines (OHC). 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.2.2.2 Cylinder 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. The most common cylinder head types are the hemi, wedge, and semi-hemi. All three of these terms refer to the shape of the engine's combustion chamber. The cylinder head carries the valves, valve springs and the rockers on the rocker shaft, this part of the valve gear being worked by the push-rods. Sometimes the camshaft is fitted directly into the cylinder head and operates on the valves without rockers. This is called an overhead camshaft arrangement. Like the cylinder block, the head is made from either cast iron or aluminum alloy.2.2.3 GasketThe cylinder head is attached to the block with high-tensile steel studs. The joint between the block and the head must be gas-tight so that none of the burning mixture can escape. This is achieved by using cylinder head gasket. This is a sandwich gasket, i.e. a sheet of asbestos between two sheets of copper, both these materials being able to withstand the high temperature and pressures within the engine.2.2.4 Oil Pan or SumpThe oil pan is usually formed of pressed steel. 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.New Wordsengine block 缸体cylinder head 气缸盖fasten 使固定water jacket 水套oil gallery 油道camshaft 凸轮轴overhead-cam(OHC) 顶置凸轮gray iron 灰铸铁alloy 合金nickel 镍chromium 铬casting 铸件head cover 汽缸盖罩intake manifold 进气总管distributor 分电器oil pan 油底壳aluminum 铝be lined with 镶有cylinder sleeve 气缸套hemi 半球形wedge 楔型，楔入semi-hemi 准半球形rocker 摇臂push-rod 推杆gasket 衬垫high-tensile 高强度的stud 螺栓gas-tight 密封的asbestos 石棉crankcase 曲轴箱，曲柄箱encase 封闭，把…包起来drain off 排出，流出Review Question1.What do TDC, BDC, stroke, compression ratio and engine capacity stand for?2.How do you calculate swept volume and compression ratio?3.What controls the length of the stroke?4.List the main parts of the engine overall mechanics?5.What are the main function of the engine block?2.3 Piston Connecting Rod and Crankshaft2.3.1 Piston AssemblyThe 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 create by the burning fuel mixture. This force turns the crankshaft .Thin, circular , steel bands fit into grooves around the piston to seal the bottom of the combustion chamber. These bands are called piston rings. The grooves into which they fit are called ring grooves. 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 is the pin boss.The piston itself , its rings and the piston pin are together called the piston assembly.2.3.2.PistonTo 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 take 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 The sections between the ring grooves are called ring lands.The piston crown may be flat , concave ,dome or recessed . In diesel engine , the combustion chamber may be formed totally or in part in the piston crown , depending on the method of injection . So they use pistons with different shapes.2.3.3Piston RingsAs Fig.2-9 shows , piston rings fit into ring grooves near the 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 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 from entering the combustion chamber , and is called an oil ring. Chrome-face cast-iron compression rings are commonly used in automobile engines. The chrome face provide a very smooth , wear-resistant surface.During the power stoke , combustion pressure on the combustion rings is very high. It causes them to untwist . Some of the high-pressure gas gets in back of the rings. This force the ring face into full contact with the cylinder wall. The combustion pressure also holds the bottom of the ring tightly against the bottom of the ring groove. Therefore , high combustion pressure causes a tighter seal between the ring face and the cylinder wall.2.3.4 Piston PinThe piston pin holds together the piston and the connecting rod . This pin fits into the piston pin holes and into a hole in the top end of the connecting rod. The top end of is much smaller than the end that fits on the crankshaft . This small end fitsinside the bottom of the piston . The piston pinfits through one side of the piston , through thesmall end of the rod , and then through the otherside of the piston . It holds the rod firmly in place inthe center of the piston. Pins are made ofhigh-strengh steel and have a hollow center . Manypins are chrome-plated to help them wear better.2.3.3 Connecting rodThe connecting rod is made of forged high-strengthsteel . It transmits and motion from the piston to the crankpin on the crankshaft . The 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 fits the crankshaft journal . This is called the big end . For this big-end bearing , steel-backed lead or tin shell bearing 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 to be withdrawn through the cylinder bore . The connecting rod is made from forged alloy steel .2.3.5 CrankshaftThe crankshaft , in conjunction with the connecting rod , coverts the reciprocating motion of the piston to the rotary motion needed to drive the vehicle . It is usually made from carbon 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 whells 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 .2.3.6 FlywheelThe flywheel is the made from carbon steel . It fit s onto the rear of the crankshaft . As well as keeping the engine rotating between power strokes it also carries the clutch , which transmits the drive to the transmission , and has the starter ring gear around its circumference . There is only one working stroke in four so a flywheel is needed to drive the crankshaft during the time that the engine is performing the non-power strokes .New Words Comprise 由。
