1.Todays,a average car contains more than 15000 separate, individual parts that must work together. T hese parts can be grouped into four major categories: body,engine,chassis and electrical system.
当今汽车的零部件总数通常多达15000种以上，它们协同工作。汽车零部件分成4大主要类别：车身、发动机、底盘和电子电器系统。
2. Gasoline and Diesel are called heat engines, the burning fuel generates heat which causes the gas in side the cylinder to increase its pressure and supply power to rotate a shaft connected to the power trai n.
汽油机和柴油机被称为热机，车用燃料产生热量使得气缸里的气体压力升高，为传动系统的曲轴提供动力。
3. An automatic transmission performs similar functions to a manual transmission except that gear sele ction is controlled either htdraulically or electronically.
自动变速器选择档位由液压或者电控方式控制，其余方面，自动变速器和手动变速器的功能类似。
4. The purpose of the complete suspension system is to isolate the vehicle body from road shocks and vibrations, which will otherwise be transferred to the passengers and load.
悬架系统的功能是隔离、缓减路面冲击和振动,避免传递到车身,影响乘客和货物的舒适性和安全性。
5. All vehicles must fitted with at least 2 independent brake systems. They were once called the servic
e brake and the emergency brake.
所有汽车都必须配备两套独立的制动系统，即行车制动和紧急制动。
6. The pressure developed within the combustion chamber is applied to the head of a piston to produce
a usable mechanical force.
燃烧室内的压力作用在活塞顶部产生有用的机械功。
7. The valve system is made up of those parts needed to open and close the valves at just the right time . 气门系统由那些在正确时间开启和关闭气门的零部件组成。
8. The burned gases removed from the combustion chamber contain such harmful emissions as hydroc arbons,carbon monoxide and nitrous oxides.从燃烧室里排除的废气含有有害的成分：HC、CO和NOx
9. The location of the driving axle determines whether the vehicle is classified as rear-wheel drive,fron t-wheel drive,four-wheel drive or all-wheel drive.
驱动桥的位置决定驱动方式的类型：后驱、前驱、四轮驱动和全轮驱动。
