Robert: Driving is probably tf us will ever do. So we must drive carefully.
Lucy: The problem is now on a truly global scale. I don’t believe that any single country can do anything about it.
Jack: I think you’re right. There needs to be an international response to this problem.
Lucy: Yes, I agree. The air here is much more polluted than in my country. Of course, my country is more agricultural and has much less industry.
Jack: We have reduced emission of air pollutants in recent years, but cars are still a major source of them. Factories have become cleaner as stricter environment pollution laws have been introduced.
Tom: Yes, even if you drive responsibly and defensively, you still need to know what to do just in case you end up in a collision.

UNIT TWO P18An automobile probably has about 7,000 different parts in it. Some of them make it more comfortable or better looking, but most of them are to make it run.一台车可能有７０００多个不同的零件。
一些使它更舒适或外观更好看。
但大部分是使它能运转的。
The three basic components of the automobile are the engine, chassis and body.汽车基本三大组成部分是发动机，底盘和车身．The engine converts the fuel energy into mechanical power. An internal combustion engine powers our modern automobile. The engine burns its fuel within the engine proper, as compared to a steam engine where the fuel is burned externally. The gasoline and air mixture of the internal combustion engine is compressed by a piston inside an airtight cylinder and ignited by a spark. The trapped air-fuel mixture burns fiercely, causing tremendous heat which expands the trapped gases and pushes the piston down. This is the motive power of the automobile. The automobile engine is essentially a heat engine. It requires fuel to burn, a spark to ignite, lubrication to minimize friction, and a cooling system to dissipate unwanted heat.发动机把燃油的能量转化成机械能．内燃机给现代的汽车提供动力。

The engine gives the power to the automobile. And without the engine, the automobile will not move, so the engine is often called the ―heart‖ of the automobile. It turns fuel into the energy of autopower. According to the different types of fuel used, the engine can be classified as being either a gasoline engine or a diesel engine. The most common automobile engine is the gasoline engine.

TCS 牵引力控制系统
TCS是英文Traction Control System 三个字的简写，中文为「循迹控制系 统」就是防止轮胎打滑空转控制系统。 即牵引力控制系统。汽车在光滑路面 制动时，车轮会打滑，甚至使方向失 控。同样，汽车在起步或急加速时， 驱动轮也有可能打滑，在冰雪等光滑 路面上还会使方向失控而出危险。 TCS就是针对此问题而设计的。TCS 依靠传感器探测到从动轮速度低于驱 动轮时（这是打滑的特征），就会发 出一个信号，调节点火时间、减小气 门开度、减小油门、降挡或制动车轮， 从而使车轮不再打滑。防止车辆失控 甩尾。 TCS可以提高汽车行驶稳定 性，提高加速性，提高爬坡能力。原 来只是豪华轿车上才安装TCS，现在 许多普通轿车上也有。TCS如果和 ABS相互配合使用，将进一步增强汽 车的安全性能。

Spark-ignition engines use an electric ignition system with spark plugs. Electric sparks at the spark plugs ignite, or set fire, the fuel in the engine cylinders. The compression-ignition engine uses the heat of compression to ignite the fuel. When air is compressed, it gets very hot. The diesel fuel is sprayed into this very hot air and is ignited by the heat.
UNIT 2 AUTOMOTIVE ENGINE
2 . Engine engines are used in automotive vehicles. The two major types are:
(a) The piston engine in which pistons move up and down, or reciprocate, in the engine cylinders. This is the engine used in all cars today, except for some models of Mazda.
Each performs a basic job in making the engine run. These are described briefly below.
UNIT 2 AUTOMOTIVE ENGINE
3 . 1 Fuel system
• The fuel system supplies gasoline or diesel fuel to the engine. • This fuel is mixed with air to make a combustible mixture (a mixture that will burn) . • Each cylinder is repeatedly filled with the mixture. Then, the mixture is ignited and burned, producing high pressure. • The high pressure makes the pistons move (or rotors spin) . • This turns shafts that rotate the wheels, causing the vehicle to move.
(b) The Wankel rotary engine in which rotors rotate, or spin. The Mazda Motor Corporation of Japan is the major manufacturer of this engine.
