1.Engine
The engine acts as the power unit. There are two types of engine: gasoline engine (also called a spark-ignition engine) and diesel engine (also called a compression-ignition engine). All engines have fuel, exhaust, cooling, and lubrication systems. Gasoline engines also have an ignition system. The ignition system supplies the electric spark needed to ignite the air-fuel mixture in the cylinders. The fuel system stores liquid fuel and delivers it to the engine. The fuel is mixed with air to form a combustible mixture in the carburetor, the manifold, or the cylinders themselves. The cooling system removes excessive heat from the engine. Air and a coolant are used to carry away the heat. The lubrication system is important in keeping the engine running smoothly. Motor oil is the lubricant used in the system.

Section 1 Automotive Basics Section 4 Automotive design and Manufacturing
The power train system comprises clutch, transmission, propeller shaft, rear axle and differential and the driving road wheels. The clutch or torque converter has the task of disconnecting and connecting the engine's power from and to the driving wheels of the vehicle. The main purpose of the transmission or gearbox is to provide a selection of gear ratios between the engine and driving wheels, so that the vehicle can operate satisfactorily under all driving conditions. Gear selection may be done manually by the driver or automatically by a hydraulic control system.

知识拓展
要点分析： driving wheels 参考译文：驱动轮
从动轮是什么？是Driven wheels !
Driven wheels 还有“驱动轮”（被发动机驱 动）的意思。
只有联系上下文确定其具体指什么。

1.1 Basic Parts of Automobile
The function of the propeller (drive) shaft is to transmit the drive from the gearbox to the input shaft of the rear axle and differential assembly. Flexible joints allow the rear axle and wheels to move up and down without affecting operation. The rear axle and differential unit transmits the engine's rotational power through 90° from propeller shaft to axle shaft to road wheels. A further function is to allow each driving wheel to turn at a different speed when cornering. A third function is to introduce another gear ratio for torque multiplication.

2. Body
An automobile body (Fig.1-2) provides a protective covering for the engine, passengers, and cargo. The body is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modern appearance for the vehicle. It is streamlined to lessen wind resistance and to keep the car from swaying at the driving speeds.
