Unit 1
1. If you know something about ordinary gasoline engines, you will have notice that diesel engines, in many
respects, work in the same way as gasoline engines (柴油机的工作方式在很多方面与汽油机是一样的).
2. The engine is the source of power that drives the car (使得汽车行驶).
3. As it would not be reasonable to have to stop the engine every time it was required to stop the car (每次
要停车).
4. Some of parts make the car more comfortable or better looking (有些部件使得汽车更舒适或美观),but
most of them are to make it run.
5. Not all of this heat can be used, and if allowed to remain in the engine (如果让其热量保留在发动机中).
it would soon destroy it.
Unit 2
1. We want hybrid-electrid vehicle that reflect the spirit of the time (要能反映出时代精神)and vehicle
concepts that express their individuality.
2. There are various types of engines such as electric motors, steam engines and internal combustion
engines (电动机、蒸汽机和内燃机)
3. The transmission is a speed and power changing device (一个使速比变化的装置).
4. Scientists have still been making efforts to concentrate the future development of engines on the three
targets: reducing fuel consumption, lowering exhausted emissions, and reducing engine noise (减
少耗油量、降低废气排量以及发动机噪声).
5. Hybrid systems are increasingly becoming more prevalent (正日益变得更加流行) in light-duty
vehicles,but also in transit buses and other heavy-duty vehicles.
Unit 3
1. The tappets are to transmit the force from the camshaft to the pushrods (把凸轮轴的力传递到推杆).
2. The intake valves heat less during engine operation (进气门在发动机运转中产生的热量较少),since
they are cooled by incoming air or fuel-air mixture on the intake stroke.
3. The valve spring provides the force necessary to close the valve (气门弹簧产生用来关闭气门的弹力)
and hold it tightly against its seat.

4. To keep the engine in good working trim, the valve train should undergo regular maintenance (配气机
构应该进行定期保养).
5. The more cylinders an engine has, the more power strokes produced for each revolution (每转的做功
行程就越长).
Unit 4
1. The lighting system changes current into light and the horn change current into sound (把电流变成光,
而喇叭将电流变成声音).
2. We know that every vehicle has its own ignition system and is started by it (每辆车都有自己的点火系,
而点火系用以起动汽车).
3. The ignition system usually consists of these parts such as spark plugs、wire、 distributor、 ignition
coil、and source of electrical current (由火花塞、导线、分电器、点火线圈和电源等部件组成)。
4. If the battery were the only supply of electrons necessary to operate all of the automotive electrical
equipment, it would soon become discharged (那么蓄电池不久就会把电放完).
5. The mixture comes to explode burning (混合气会产生爆燃) when ignited.

Unit 5
1. The power is then carried from the engine through the power train to the car (通过传动系从发动机传递
车轮) so that the wheel turn and the car moves.
2. If your car transmission needs repairs or replacement (如果汽车变速器需要修理和更换), you’ve come
to the right place.
3. If you wanted a top speed of 80 kmh, then the gear ratio would be similar to third gear (速比相近于3
挡) in most manual transmision 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 drive used (取决于所使用的驱
动类型).
Unit 6
1. An automobile brake system is actually a friction device to change power into heat (实际上就是一种把
动力转变成热量的摩擦装置).
2. Basically, automobile brakes are of two types: the mechanical brakes and the hydraulic brakes (机械制
动器和液压制动器).
3. The most vital factor in the running and control of the modern vehicles is the automobile brake system
(汽车制动系统)
4. There are two brake shoes at each wheel. The bottoms of the shoes are held apart by an adjuster. The
tops of shoes are held apart by a wheel cylinder (蹄片顶部由轮缸分别固定).
5. Brake lines ara steel tubing with copper and coating ` (以防锈蚀).
