汽车工程专业英语第二章
第二章：内燃机（INTERNAL COMBUSTION ENGINE）1)Energy and power:Engines used in automobiles are internal combustion heat engines. They convert the chemical energy of the gasoline into heat within a power chamber that is called a combustion chamber. Heat energy released in the combustion chamber raises the temperature of the combustion gases within the chamber. The increase 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.能源是用于生产电力。
化工能源是转化为燃料的燃烧的热量，这个过程被称为燃烧。
如果发动机燃烧发生在气缸内的地方，被称为发动机内部燃烧发动机。
如果燃烧发生在气缸外的地方，被称为发动机外部燃烧发动机。
用于汽车的能源叫内部燃烧高能源，高温能源在燃烧室里降低能缓解气体燃烧在气缸内的温度。
燃烧气体温度的升高引起气压变大，燃烧室内发展应用到了活塞产生一个可用的机械力，然后将其转换成有用的机械能。
2)Engine terms:Linking 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 ofgas movement is the duty of the valves;活塞通过连杆和曲轴连接，使得气体带动曲轴旋转半圈。

车辆工程专业英语新能源汽车综述
Characteristics and Development of Some Kinds of New Energy VehiclesAbstractNow the global automotive industry is facing the challenge of energy and environment,and developing new energy vehicles becomes many global automotive groups’s same plan.But not all of various types of new energy vehicles which have their own advantages and disadvantages can become the most promising future vehicles.I will introduce features and development of Pure Electric Vehicles 、Hybrid Electric Vehicle (HEV)、Fuel Cell Electric Vehicles (FCEV)、Natural Gas Vehicles、Hydrogen Engine Vehicles and DME Vehicles Etc. At last we will know which kind of the new energy vehicles will become mainstream in the future of the car by comparing.Key Word: New Energy Vehicles Future cars HybridHybrid cars is hybrid electric vehicles which use more than one kind of energy provides power to drives the car . Currently hybrid cars is the combination of traditional fossil fuels engin and electric motor. The most prominent advantage of hybrid cars is its fuel economy. The maximum power of the engin can determine by the average power ,so that the engin can work in less pollution and lower fuel consumption condition. That makes hybrid cars save 30%~50% fule compare with traditional cars,and significantly reducing emissions at the same time.Energy recovering from braking become easy too.But the problem of hybrid car is it’s high price and basicly no fuel saving at long distance、high speed driving.At present, China's hybrid vehicle technology development fast, some models have been in the period of practical .Take the Roewe 750 of Shanghai Automotive Group for example ,it has already on sale.In the world wild,Toyota Prius hybrid car first introduced in Japan in 1997,and the other major automobile companies havelaunched their own hybrid products, such as the Honda Insight, GM Saturn VUE, Ford Escape and so on.With technical progress and expansion of production scale,the cost has dropped significantly.Pure electric vehicles is driven by electric motor, which is powered by car-carry battery,and meet the requirements of traffic safety regulations.Pure electric vehicle using a rechargeable battery , and the basic structure is not complicated.Electric generators and car batteries are one of the key components, among which the most critical is battery.Pure electric vehicles is not a new car, the electric car was born more than 100 years. At that time the electric car battery lifespan is short, the mileage is not high also. Then the electric car is relaced by the increasingly technology mature internal combustion engine car. But in the 1970 s, due to the stimulation of oil crisis, all countries in the world began to look for other energy to replace oil. The electric car is back in the line of sight of people. And in recent years besides had the problems of energy, environmental problem has become a social focus on major issues. Againincreased focus on electric cars. Now the difficulty of promote puer electric car comes from the power storage technologies.Currently,energy storage in per unit weight of the battery is not enough for long -term using, the charge mileage is not ideal. On the other hand,The high-performance battery lifespan is short.Resulting in not froming economy scale, cost of pure electric vehicle is too high to commercial operation.Nevertheless, pure electric vehicles are promoted in the U.S., Europe, Japan in small-scale,and mainly use in government vehicle ,city bus Etc. The forerunner of China's electric car company BYD launched E6, and also exported electric bus to Europe .Fuel cell electric vehicle use a fuel cell as electric source to supply electric motor, and the chemical energy of fuel is directly changed into electrical energy by the cell.The energy conversion efficiency of the fuel cell is 2 to 3 times higher than internal combustion engines, and fuel cells do not produce harmful chemical reaction products and make lower noise.In recent years, although the development of fuel cell vehicles technology has made significant progress in the world wild , but there are still some technical challenges, such as the integration of fuel cells,vehicle integration, industrialization and commercialization. It is worth mentioning that we are at the same level with developed countries in the field of fuel cell electric vehicle researching.Hydrogen engine vehicle power by the engin which is transform from the existing automobile internal combustion engine.In addition to the hydrogen engine car has the same advantages of less pollution, lower emissions, but also has other special advantages, such as lower requirements for hydrogen, high combustion performance, engine technology is mature and so on.But now hydrogen engine car facing with problems of preparation and storage of liquid hydrogen .Ability to effectively solve these two problems in short time will determine the prospects for the development of hydrogen engine vehicles.Natural gas vehicles to use natural gas as fuel .According to the chemical composition and morphology of natural gas ,it can be classified as three kinds of it ,like Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas . Because natural gas vehicles using natural gas as fuel, so it has some feature like low pollution, low cost and high security.But natural gas vehicles have lower power performance, not easy to carry compared with normal vehicle. And once put into Large-scale using, we must build the appropriate station and pipeline.It also relates to design urban planning, funding and environmental safety, and many other factors, causing the high cost of using this kind of vehicle.China is rich in natural gas resources, and natural gas vehicle technology developed rapidly in these years . For example, some taxi Changsha use Compressed Natural Gas engin.In addition to the above new energy vehicles, as well as，there is also a kind of vehicle using organic substance, such as alcohol, ether as fuel to power the car.Ethanol fuel is ethanol automotive gasoline, ethanol vehicle technology is relatively mature, thetraditional internal combustion engine can modification to adapt to different ethanol gasoline fuel. The rapid development of ethanol cars happen in United States, Brazil and other countries thanks to the rich ethanol resources, while China is still in its initial stage.DME car use DME as fuel of compression-ignition engine. Generally using in two ways: Firstly, using the dimethyl ether as an ignition-promoting secondly dimethyl ether used as the direct combustion of liquid to get power.Dimethyl ether automobile technology in China has made important progress, such as Shanghai automotive group has successfully developed in dimethyl ether city bus, and began the trial runThanks to internal combustion engine technology is now very mature, hybrid cars is ease of using , sustainability, reliability is better than that of other new energy cars, but its still use gasoline, diesel oil as a source of energy, so the hybrid vehicle can't represent the future type of car. And because the power can be obtained from a variety of one-off energy,do not worry about energy draining, so pure electric vehicle has broad application prospects. At the same time, pure electric vehicles has no pollution, makes lower noise, is high efficiency. These advantages make this type of electric car research and application is becoming a hot spot of the car industry, and our country also take electric vehicles as the main orientation of auto industry strategic transformation. Fuel cell vehicles, with its efficient green cleaning and life advantage to get the attention of many countries to continuously invest devotion, therefore the fuel cell car will also be important form of the cars of the future. For other types of new energy vehicles, because of the limitations of fuel supplying, can't be used in the large scale all over the world. And this kind of alternative fuel in the engine power performance, corrosion, storage and transportation difficulties, such as obvious shortcomings. This kind of new energy vehicles may will be the future regional auto supplement type.Comparing the above list of various types of new energy vehicles, pure electric vehicles will be themainstream of future automobiles, fuel cell vehicles will act as an important component in the future , and a hybrid car is the transition models before exhausting of petrochemical resources, other types of cars are supplement adjust measures to local conditions. Pure electric vehicles is the most promising new energy vehicles, and is strongly supported by the state.Now some electric vehicles is used in the urban public transport, major activities.We look forward to the clean traffic early arrival of the era.References[1]邹政耀，王若平.新能源汽车技术.北京：国防工业书版社，2012[2]石川宪二.新能源汽车技术及未来.康云龙，余开江译.北京：科学出版社，2012[3]冯景毅.基于48V电压平台解读比亚迪绿混技术.汽车之家网，2013[4]黄正桥.陈斌波：电动汽车是未来汽车发展的方向.汽车之家网，2011[5]Sperling, Daniel.Two Billion Cars:Driving Toward :Oxford University Press,2009[6].Ranjan K.

通常它们有比轿车大的底盘和悬架来支撑重物质量。
轻型运载货车基于轿车的设计并改装以便腾出最大限度的空间来装载货物。
商用运载货物车辆的车身是专用设计的。
如罐车运载液体，自卸车搬运泥土或大批谷物，平板车和货车通常用来运载普通货物。
公交车或长途汽车通常是4轮固定模式的车辆，但会用到大量的车轮和轮轴。
有时，铰接式公交车是为了增加容量。
公交车和货车可以做成单层或双层的。
长途汽车常用于长距离运载，且费用比较昂贵，因此市区里就会用到公交车，如市郊间上下班时用于交通运输。
1.2 发动机发动机作为动力装置。
最常见的内燃机通过燃烧发动机气缸里的液体燃料而获得能量。
内燃机有两种类型：汽油机（又称为点燃式发动机）和柴油机（又称为压燃式发动机）。
两种类型均称为热力发动机。
燃烧燃料产生的热量使汽缸里气体的气压增加并提供能量通过传动轴连接到传动系统。
发动机气缸的排列方式称为发动机配置。

Unit 2The Basic Principle of EngineText A Classification and Main Components of EngineThe internal combustion engine is an engine in which the combustion of fuel occurs with oxygen(usually air) in a combustion chamber, as shown in Fig.2.1.1 87692 3 45Fig.2.1 Internal Combustion Engine1—the cap of the cylinder head 2—valve 3—engine block 4—flywheel 5—crankshaft 6—oil pan 7—pulley 8—cylinder 9—timing gearClassification of EngineThe engine can be classified in following ways:By Fuel SystemGasoline engine and diesel engine are used. In a gasoline engine, the air-fuel mixture is exploded in the engine. A diesel engine uses diesel fuel. It generates high power at low speeds. The fuel efficiency is better than that of a gasoline engine.Unit 2 The Basic Principle of Engine✩ By Cylinder Arrangemen tMost cars have more than one cylinder. Four, six and eight cylinders are common used. In a multi-cylinder engine, the cylinders are usually arranged in one of three ways: in-line, V-type, or flat (Fig.2.2). Today the number of cylinders is growing, the cylinders also can be arranged as W-type.(a) flat (b) V-type (c) in-lineFig.2.2 Cylinder Arrangement✩ By Cooling SystemLiquid-cooled engines and air-cooled engines are being used. Liquid-cooled engines are the most common in the engine industry.There are also other ways to classify the engines. Despite of these classifications, the structure of the engine is basically the same.Main ComponentsThe engine consists of several different mechanisms and systems including cylinder block, crankshaft and connecting rod mechanism, valve mechanism, fuel supply system, lubrication system, cooling system, ignition system and starting system.✩ Cylinder BlockThe core of the engine is the cylinder, with the piston moving up and down inside the cylinder.✩ Crankshaft and Connecting Rod MechanismThe crankshaft changes the linear movement of the piston into a rotational movement via a connecting rod. The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates.✩ Valve MechanismA valve mechanism is a group of components that opens and closes the intake and exhaust valves in the cylinder head at the appropriate time. The main functions of the valve gear are to provide timely admission of the fresh charge into the cylinders and exhaust of spent gases from them.1112汽车专业英语✩ Fuel Supply SystemThe fuel system supplies fuel to the engine. It also has the functions to regulate the volume of fuel supply. The fuel systems in diesel and gasoline engines are different.✩ Lubrication SystemThe lubrication system uses an oil pump to continuously supply engine oil throughout the inside of the engine. This system reduces friction between parts with a film of oil. If the engine is run without oil, the friction can cause poor running, or cause even meltdown. In addition to lubrication, engine oil cools and cleans the engine.✩ Cooling SystemThe cooling system regulates the engine temperature to an optimal level (80℃ to 90℃ at coolant temperature) by circulating the coolant throughout the engine under all operating conditions and during all seasons of the year. The cooling fan cools the coolant in the radiator and water pump circulates the coolant through the cylinder head and the cylinder block.✩ Ignition SystemInternal combustion engines require ignition of the mixture, either by spark ignition (SI) or compression ignition (CI).✩ Starting SystemThe starting system forces the engine to crank with an electric motor, and starts the engine.Text B Engine Operating PrinciplesA four-stroke engine, also known as four-cycle, is an internal combustion engine in which the piston completes four separate strokes ：intake, compression, power and exhaust —during two separate revolutions of the engine’s crankshaft, and one single thermodynamic cycle.The main parts in four stroke engine are shown in Fig.2.3.Fig.2.3 Main Parts in Four Stroke Engine1—intake valve 2—spark plug 3—exhaust valve 4—combustion chamber 5—piston head13Unit 2 The Basic Principle of EngineAs their name implies, four-stroke internal combustion engines have four basic steps that repeat with every two revolutions of the crankshaft:① Intake stroke ② Compression stroke, ③ Power stroke, ④ Exhaust stroke. The four strokes will be illustrated in Fig.2.4.They draw in an air-fuel mixture to the cylinders, compress it, ignite and combust it, then discharge it. Repeating these four actions gives gasoline engines their power. The cycle begins at Top Dead Centre (TDC), when the piston is farthest away from the crankshaft. A cycle refers to the full travel of the piston from TDC to Bottom Dead Centre (BDC).✩ Intake StrokeOn the intake stroke of the piston, the piston descends from (TDC,BDC) to (TDC, BDC), reducing the pressure inside the cylinder. A mixture of fuel and air, or just air in a diesel engine, is forced by atmospheric pressure into the cylinder through the intake port. The intake valve(s) then (open,close).✩ Compression StrokeWith both intake and exhaust valves (open,close), the piston returns to the top of the cylinder compressing the fuel-air mixture into the combustion chamber of the cylinder head.✩ Power StrokeIt is also named as combustion stroke. While the piston is close to (TDC,BDC), the compressed air –fuel mixture is ignited. The resulting massive pressure from the combustion of the compressed fuel-air mixture forces the piston back down toward (TDC,BDC).✩ Exhaust StrokeDuring the exhaust stroke, the piston once again returns to (TDC,BDC) while the exhaust valve is (open,close). This action evacuates the burnt products of combustion from the cylinder by expelling the spent fuel-air mixture out through the exhaust valve(s)..(1) intake (2) compression (3) power (4) exhaustFig.2.4 Four Stroke Cycle汽车专业英语NEW WORDS AND PHRASESprinciple [ ] n. 原理，法则classification [ ] n. 种类，类别configuration [ ] n. 布局，构造oxygen [ ] n. 氧气combustion [ ] n. 燃烧chamber [ ] n. 室，房间component [ ] n. 成分，部件，零件force [ ] n. 力gasoline [ ] n. 汽油diesel [ ] n. 柴油；柴油机explode [ ] n. 爆炸，爆发rotational [ ] adj. 旋转的in-line [ ] adj.

车辆工程专业英语概述
车辆工程专业英语概述The Principal Components Of Automotive张可可2021210612The Principal Components Of Automotive contains the body, the engine , the chassis , the power train system, the steering system, the suspension system and wheels , the braking system and the electrical and electronic system.1 The bodyAn automobile body is a sheet metal shell with windows, doors, a hood anda trunk deck built into it.It provides a protective covering for the engine, passengers and cargo. It is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modern appearance for the vehicle.2 The 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 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 torotate a shaft connected to the power train.3 The chassisChassis is the frame on which the engine, body, wheels etc. are built. The chassis is an assembly of those systems that are the major operating parts ofa vehicle. It includes power train which conveys the drive to the wheels, steering which controls the direction of movement，suspension and wheels which absorb the road shocks, and brake which slows down the vehicle.4 The power train systemThe power train transfers turning effort from the engine to the driving wheels. It include a clutch ( manual transmission) or a torque converter (automatic transmission), a transmission drive shaft, final drive and differential gear s and driving axles. Alternatively, a transaxle may be used.A transaxle is a self-contained unit with a transmission, final drive gears and differential located in one casing.The directional motion of vehicle is controlled by a steering system. A basic steering system has 3 main parts: a steering box connected to the steering wheel, the linkage connecting the steering box to the wheel assembly at the front wheels and front suspension parts to let the wheel assemblies pivot. When the driver turns the steering wheel，a shaft from the steering column turns the steering gear. The steering gear movestie-rods that connect to the front wheels. The tie-rods move the front wheels to turn the vehicle right or left.5 The braking system and wheelsThe purpose of the complete suspension system is to isolate the vehicle body from road shocks and vibrations, which will otherwise be transferred to the passengers and load. It must also keep the tires in contact with the road regardless of road surface. A basic suspension system consists of springs, axles, shock absorbers, arms, rods and ball joints.The tire provides a cushion between the vehicle and the road to reduce the transmission of road shocks. It also provides friction to allow the vehicle to perform its normal operations. Modern tires are manufactured from a range of materials. The rubber is mainly synthetic. Two types of tire construction are common: cross-ply and radial. Most passenger cars now use radial tires, and radials are replacing cross-ply tires on 4-wheel drives and heavy vehicles.6 The braking systemDrum brakes have a drum attached to the wheel hub, and braking occurs by means of brake shoes expanding against the inside of the drum. With disc brakes, a disc attached to the wheel hub is clenched between two brakepads. On lightvehicles, both of these systems are hydraulically operated. The brake pedal operates a master cylinder. Hydraulic lines and hoses connect the master cylinder to brake cylinders at the wheels. Most modern light vehicles have either disc brakes on the front wheels and drum brakes on the rear or disc brakes on a11 4 wheels. Disc brakes require greater forces to operate them. A brake booster assists the driver by increasing the force applied to the master cylinder when the brake is operated.7 The electrical and electronic systemThe charging system provides electrical energy for all of the electrical components on the vehicle. A typical charging system includes: a battery, an alternator, a voltage regulator which is usually integral to the alternator, a charging warning or indicator light and wiring that complete the circuits. The battery provides electrical energy for starting, then once the engine is running the alternator powers all the electrical components of the vehicle. The alternator also charges the battery to replace the energy used to start the engine. The voltage regulator prevents overcharging. The starting system consists of the battery, starter, flywheel ring gear, cables，and the ignition switch. The starter motor is powered by the battery. During starting, the pinion of the starter motor engages withthe flywheel ring gear and the starter motor then operates to crank the engine.Electrical is related to the electricity while electronic related to the semi-conductor or microcomputers. The electrical system provides electricity to the starter, ignition, lights and heater. The electricity level is maintained by a charging circuit.That's all.感谢您的阅读，祝您生活愉快。

The Principal Components Of Automotive张可可2013210612 The Principal Components Of Automotive contains the body, the engine , the chassis , the power train system, the steering system, the suspension system and wheels , the braking system and the electrical and electronic system.1 The 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. It is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modern appearance for the vehicle.2 The 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 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 power train.3 The chassisChassis is the frame on which the engine, body, wheels etc. are built. The chassis is an assembly of those systems that are the major operating parts of a vehicle. It includes power train which conveys the drive to the wheels, steering which controls the direction of movement，suspension and wheels which absorb the road shocks, and brake which slows down the vehicle.4 The power train systemThe power train transfers turning effort from the engine to the driving wheels. It include a clutch ( manual transmission) or a torque converter (automatic transmission), a transmission drive shaft, final drive and differential gear s and driving axles. Alternatively, a transaxle may be used. A transaxle is a self-contained unit with a transmission, final drive gears and differential located in one casing.The directional motion of vehicle is controlled by a steering system. A basic steering system has 3 main parts: a steering box connected to the steering wheel, the linkage connecting the steering box to the wheel assembly at the front wheels and front suspension parts to let the wheel assemblies pivot.
