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.

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).

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).
