The power train has two maan functions :it conveys powerfrom the engine to the wheels , and it changes the amount of torque2. The power train consists of an engine , a transmission ,a clutch , a drive shaft and differential3. The feature of a manual transmission is to deliver enginepower to the front wheels and rear wheels4. manual transmissions usually have five speeds , which means that the output shaft can rotate faster than the input5. There are several basic components in the clutch , suchas the flywheel , clutch disk , pressure plate , release bearing and linkage.6 Automatic transmissions are used not only in many rear-wheel-dnve and four-whe el-dnve ve- lcles, but In most front-wheel-dnve ones1.T2.

Instead, they use an amazing device called a torque converter.3.One important function of the power train is to transmit the power of the engineto the wheels.4.The type of transmission ( manual or automatic) determines how the slip joint isconnected to the drive shaft.5.The clutch is located between the back of the engine and the front of thetransmission6.The face of the flywheel that touches the clutch disc is made of iron Even if theflywheel were aluminum , the face is iron.7.When the operator presses the clutch pedal ,the clutch release lever or fork .8.The clutch release bearing in most cases, is a ball bearing assembly with amachined face on one side.E41.clutch : any of various devices for engaging and disengaging two working engagingand disengaging two working parts of a shaft2.shaft: a long, generally cylindrical bar, especially one that rotates and transmits power3.transmission : a speed and power changing device4.gearshift : a mechanism for changing from one gear to another in a5.transaxle : an automotive part that combines the transmission and the differential and is used on vehicles with front-wheel drive6.flywheel: a heavy-rimmed rotating wheel used to minimize variations in angular velocityE51.The power is then carried from the engine through the power train to the car (通过传动系扒发动机传递到车轮) so that the wheels turn and the car moves.2.( 如果汽车变速器需要修理和更换)If your car transmission needs repairs orreplacement，you’ve come to the right phone.3.If you wanted a top speed of 80 km/h，then the gear ratio would be similar tothird gear ( 速比相近于3 挡) ,in most manual transmission cars .4.The torque converter does not require any regular maintenance or adjustments( 不要求定期维护或调整) ，but it may be possible to change the transmission fluid .5.The drive shaft can be. either open or enclosed , depending on the type of driveused (取决于所使用的驱动类型)U6E11 If your brakes can work properly , good brakes are essential for safety during dn、ruvtg.2.

汽车专业英语原文翻译
第一单元发动机分类及工作原理课文A发动机的分类所有的汽车发动机都是内燃机（ICE),就是将燃油在气缸内进行燃烧，并将燃烧产生的膨胀压力转变成转动力，用来驱动汽车。
所以说，发动机是动力源, 并被认为是汽车的心脏。
汽车发动机根据工作方式分为往复式发动机和转子发动机：报据发动机燃烧的燃料分为汽油机和柴油机：根据发动机的气缸数量和气缸排列方式分为直列发动机、V型发动机、对置式发动机和W型发动机。
往复式发动机和转子发动机往复式发动机也称为活塞式发动机。
该发动机采用一个或多个活塞在气缸内上下运动或前后运动，将压力转变为转动动能传递给汽车驱动轮（见图1-1)。
往复式发动机广泛应用现代汽车上。
转子发动机是于1954年研发出来的。
如图1-2所示，在该发动机中，有个三角形的转子在燃烧室内旋转。
膨胀气体使转子旋转，产生动力并排出废气。
转子发动机没有活塞和气门等往复部件。
转子发动机产生马力大、无振动，但其燃油消耗比往复式发动机要高。
汽油机和柴油机汽油机以汽油作为燃料。
采用火花塞点燃缸内的可燃混合气，产生动力使汽车行驶，如图1-3a所示。
汽油机也称为火花点燃式发动机。
该发动机的特点是转速高，运行平顺，结构简单，重量轻，成本低。
几乎所有轿车都采用汽油机。
柴油机以柴油作为燃料。
该发动机的工作原理足通过压缩缸内的空气使其升温，冉使喷油嘴喷入的柴油燃烧，产生动力驱动汽车(见图1-3b)，所以也称为压燃式发动机。
柴油机要比汽油机的动力更强劲，燃油经济性更好。
常见于所有的大型货车、客车和部分轿车上。
直列发动机，V型发动机，水平对置式发动机，W型发动机通过气缸数最和气缸排列方式可以识别发动机结构。
当今所有的紧凑型轿车都配有4缸发动机，一些中型级轿车配有6缸发动机，大型轿车配有8缸或12缸发动机。
在多气缸发动机上，气缸通常以四种排列方式中的一种排列，有：直列式、V型、水平对置式和W型。
直列式发动机中的气缸按直线排列，采用一个气缸蓝。
几乎所有4缸发动机都采用该种排列（兄阁1-4)。

Intermediates
Also called mid-sized cars, intermediates provide what many consider to be the best trade-off between economy and comfort. Parking maneuverability and fuel economy are superior to the full-size models, while maintenance access, roominess and long-trip comfort are better than those of the compacts and subcompacts. Intermediates have room for five adults and a large trunk (boot). Engines are more powerful than compact cars and 6-cylinder engines are more common than in smaller cars. Car sizes vary from region to region; in Europe, large family cars are rarely over 4700 mm long, while in North America they may be well over 4800 mm.

控制器局域网CAN总线技术
现代汽车中所使用的电子控制系统 和通讯系统越来越多，如发动机电 控系统、 自动变速器控制系统、 防抱死制动系统(ABS)、自动巡航 系统(ACC)和车载多媒体系统等， 这些系统之间。系统和汽车的显示 仪表之间，系统和汽车故障诊断系 统之间均需要进行数据交换，如此 巨大的数据交换量，如仍然采用传 统数据交换的方法，即用导线进行 点对点的连接的传输方式将是难以 想象的，据统计，如采用普通线索， 一个中级轿车就需要线索插头300 个左右，插针总数将达到2000个 左右，线索总长超过1. 6Km，不但 装配复杂而且故障率会很高。因此， 用串行数据传输系统取而代之就成 为必然的选择
TCS 牵引力控制系统
TCS是英文Traction Control System 三个字的简写，中文为「循迹控制系 统」就是防止轮胎打滑空转控制系统。 即牵引力控制系统。汽车在光滑路面 制动时，车轮会打滑，甚至使方向失 控。同样，汽车在起步或急加速时， 驱动轮也有可能打滑，在冰雪等光滑 路面上还会使方向失控而出危险。 TCS就是针对此问题而设计的。TCS 依靠传感器探测到从动轮速度低于驱 动轮时（这是打滑的特征），就会发 出一个信号，调节点火时间、减小气 门开度、减小油门、降挡或制动车轮， 从而使车轮不再打滑。防止车辆失控 甩尾。 TCS可以提高汽车行驶稳定 性，提高加速性，提高爬坡能力。原 来只是豪华轿车上才安装TCS，现在 许多普通轿车上也有。TCS如果和 ABS相互配合使用，将进一步增强汽 车的安全性能。

In recent years R-134a (CH2F-CF3) is widely used as
refrigerant instead of R-12 in air conditioning
system. It has more advantages than R-12.It does not deplete the ozone layer which helps to protect us from the ultraviolet from the sun, and its evaporative temperature is higher than that of R-12.

• Its reciprocating movements in the cylinder transform the energy of the expanding gases into mechanical energy．
• Crankshaft and flywheel group includes the • following components (see Fig. 2-5):
• Crankshaftis one of the most important parts in the engine．
• It is held in the crankcase in the cylinder block and converts the reciprocating motion of the pistons into a rotary motion for the drive wheels．
Unit Two Engine Construction
Passage A Crank Mechanism and Its Main
Components
• Crank mechanism is one of the major motion mechanisms of the engine．
• Its function is to transform the reciprocating movement of pistons into rotary movement of the crankshaft, offering torque to make the drive wheels turn (see Fig.2-1).
• In a 4-cylinder engine, the crankshaft usually has three main journals and four crank pins attached to the big ends of the connecting rods．
• Every crankshaft has counter weights whose purpose is to balance the weight of the connecting rods．
• Its front end is used to drive the valve train, water pump and cooling fan, and its rear end is used to install the flywheel．
• Flywheel is a rotating disk located on one end of the crankshaft．
• Cylinder head is bolted to the top of the cylinder block with a gasket in between sealing the block and forming the combustion chambers with the cylinders．
• Piston and connecting-rod group has some main components as follows (indrical shaped hollow part made of aluminum alloy．
• It has a small end and a big end．
• The small end attaches to the piston with the piston pin and the big end connects to the crank pin of the crankshaft．
• Piston rings are inserted in the ring grooves on the top of the piston．
• Most pistons have three rings: the top two are compression rings and the lower ring is an oil ring．
• Cylinder head holds camshafts, valves, spark plugs and injectors．
• Oil panis at the bottom of the cylinder block．
• It is a container for storage of engine oil．
• They function as sealing between the piston and cylinder wall, lubricating, heat transferring and piston supporting in the cylinder．
• Connecting rod connects the piston to the crankshaft．
• Crank mechanism is divided into 3 groups: block group; piston and connecting-rod group; and crankshaft and flywheel group．
• The block group contains the following main components (see Fig. 2-2):
• It has a ring gear around the disk．
• Its purposes are to reduce vibration caused by the power stroke through its inertia, and to start the engine when the starter meshes with it．
