2. Directions: Read the following sample dialogue and try to perform your own task.
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。

2.1 Main Types of New Energy Automobile
New energy vehicles include hybrid electric vehicles, pure electric vehicles (including solar cars), fuel cell electric vehicles, hydrogen engine cars and other new energy vehicles, etc.
2.2 The Development of New Energy Vehicle History
The definition of new energy vehicles, electric vehicles is a kind of new energy vehicles. The types of new energy vehicles from the original pure electric vehicles to several kinds of new energy vehicles today has experienced a long process, in world history, the invention of the electric car than internal combustion engine car. Therefore, new energy vehicles is one of the most ancient car. The development of new energy vehicles has the following several major stages.

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.

There are two types of piston engines-spark ignition (SI) and compression ignition (CI) .
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.

UNIT 2 AUTOMOTIVE ENGINE
Some cars have the engine mounted in back of the front seat. This is called a mid-engine arrangement. Other cars have been built with the engine mounted at the rear, in back of rear seat. The Volkswagen“ beetle” is an example of rear.

UNIT 2 AUTOMOTIVE ENGINE
1 . Purpose and Locations of Engines
The purpose of an automotive engine is to supply the power needed to move the vehicle. The engine produces this power by burning fuel inside it. Because the engine burns fuel inside, or internally, the engine is known as an internal combustion engine ( ICE)
UNIT 2 AUTOMOTIVE ENGINE
3 . Basic Engine Systems
A spark-ignition engine requires four basic systems to run. Diesel engines require three of these systems. They are fuel system, ignition system (except diesel) , lubricating system and cooling system.
UNIT 2 AUTOMOTIVE ENGINE
Most automotive engines are located at the front of the vehicle. Many engines drive the rear wheels. This requires a long drive shaft extending from the front wheels to the rear wheels. Other engines drive the front wheels. In the rear-wheel-drive arrangement, the engine sits longitudinally. Its long dimension is from front to back.
