11、tem 中译:汽车综合控制系统四、翻译Translate the following sentences into Chinese。1. 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 and diesel .Both engines are called heat engines; the burning fuel g

12、enerates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the power train .内燃机是最常见的,其动力来自气缸里液体燃料的燃烧。发动机有汽油机和柴油机两种,都称为热机。燃料燃烧产生热量,气缸内气体压力升高,从而提供动力,带动连接传动系的轴旋转。2. The engine acts as the power unit. The internal combustion engine is

13、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 a compression-ignition engine. Both engines are called heat engines; the burning fuel generates heat which cau

14、ses the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the power train.发动机作为动力设备,常见的类型是内燃机,其原理是通过发动机缸内的液体燃料燃烧而产生能量。发动机可分为两类:汽油机(点燃式和柴油机(压燃式,都属于热力发动机。燃料燃烧产生热量使缸内气压上升,产生的能量驱动轴旋转,并传递给动力传动系。3.The basic steering system in most cars is the same. The steeri

15、ng gear of steering box is the heart of the steering system. This usually is next to the engine. A shaft extends from the back of the steering gear. This shaft is connected to the steering column or steering shaft. The steering wheel is at the top of the steering column. Another shaft comes from the

16、 bottom of the steering gear. This shaft connects to the arms, rods, and links. This parts assembly, called the steering linkage, connects the steering gear to the parts at the wheels. The wheels and tires mount to the steering knuckles. The knuckles are pivoted at the top and bottom. Thus, the whee

17、ls and tires can turn from side to side.在大多数汽车转向系统基本是相同的。转向箱转向齿轮转向系统的核心。这通常是旁边的发动机。轴与转向齿轮的背面延伸。该轴连接到转向柱和转向轴。方向盘在转向柱的顶部。来自另一个轴的转向器底部的。该轴连接到臂,杆,和链接。这零件装配,称为转向传动机构,与转向齿轮零件在车轮。车轮和轮胎安装在转向节。指节铰接在顶部和底部。因此,车轮和轮胎可以从一边到另一边。4. In the recirculating ball steering gear, the wormshaft is the input shaft. The worms

18、haft connects to the steering column in such a way that a mechanic can remove the steering gear or steering column independently of one another. The sector shaft (also called the pitman shaft is like the output shaft of the steering gear. The main parts of the steering gear are the balls, ball nut, and the gear teeth on the ball nut.As the wormshaft turns, the balls move the ball nut up and down along the wormshaft. This turns the s
