7.hybrid-electric vehicle 混动汽车

8.mass production大规模生产

9.dual-fuel vehicle 双燃料汽车

10.air-cooled engine 风冷式发动机

二．

1. A diesel engine compresses its cylinder air on its compresstion stroke before any

fuel enters the cylinder

2.The internal combustion engine is the one most commonly used in the

automotive field.

3.According to the fuel energy used,the internal combustion engines are also

divided into gasoline engines,and diesel engine.

4.The piston converts the potential energy of the fuel into the kinetic energy.

5.The power production cycle consists of four strokes of the position in a

reciprocating engine.

6.The engine is generally considered the “heart” of an automobile

7.This four strokes cycle of piston within the cylinder is repeated time and again to

push the vehicle foreard.

8.There are actually various types of engines such an electric engines,steam

engines,and internal combustion engines.

1. compression ratio : the total volume divided bv the compression volume

2. internal combustion engine : burning their fuel inside their cylinders

3. engine : a heart of an automobile

4. stroke : the movement of the piston within the cylinder and the distance of piston travel

5. reciprocating : the up and down action of a piston in the cylinder

6. gasoline : a mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum.

四．

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和汽油机是一样的）

2.The engine is the source of power that makes the car and the truck move.(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.(每次都到停车)

4.Some of parts make the car move comfortable or better looking, but most of

them are to make it run.(有些部件使得汽车更舒适或更美观)

5.Not all of this heat can be used, and if allowed to remain in the engine, it would

soon destroy it.(如果让其热量保留在发动机中)

一、

1.gasoline engine 汽油机

2.in low-speed driving condition在低速行车条件下

3.achieve a variety of different objectives 达到各种不同的目的

4.higher energy density高能量密度

5.electric motor 电动机

6.air conditioning空调装置

7.regenerative braking 反馈制动

8.power source动力源

9.resource consumption 资源消耗

10.dashboard display汽车仪表板显示

二、

1.The engine converts the expanding force of combustion into rotary force used to

propel the vehicle.

2.The gasoline engine and electric motor shut off automatically so that energy is

not wasted in idling.

3.Clean cities uses hybrid electric vehicles as a way for coalitions to reduce

petroleum consumption.

4.Any vehicle without a transmission could be made to move but not smoothly.

5.The electric motor applies resistance to the drive-train causing the wheels to

slow down.

6.The engine turns a high-speed generator, producing electricity.

7.An intelligent power-control system determines the most efficient operation of

the engine and energy storage system.

8.If 10000 hybrid-electric vehicles were on the road rather than current standard

vehicles, substantial reductions in emissions and fuel use would occur annually.
