第4讲 Engine Ignition, Starting and Charging System
（发动机点火、起动和充电系统）
1. Engine Ignition System
The ignition system is used to ignite the air and fuel in the cylinder. In order to do this a very high voltage is needed to force the electrical current to jump across the spark plug gap and cause an electrical spark. However, there is only 12-volt battery within the automobile. The ignition system is designed to increase the voltage to the necessary amount at the right time for the spark to occur. In addition, the time of spark must be altered as speed and load increase or decrease.

（2） The Cylinder Head The cylinder head is bolted to the cylinder block. The top of the cylinder block is covered with the cylinder head which contains the combustion chamber （Fig.2-1）.
（2） Flywheel The flywheel is a comparatively heavy wheel, bolted to the flywheel flange on the rear end of the crankshaft. The inertia of the flywheel tends to keep it rotating at a constant speed. The flywheel also has several other functions, for example, the flywheel has ring gear in its outer circumference,which mesh with teeth located on the starting motor drive pinion in order to crank the engine over. In addition, the rear surface of the flywheel serves as the driving member of the clutch assembly （Fig.2-2）.

2．Tappet, Pushrods and Rocker Arms Tappet rests on a cam of the camshaft. The pushrod is a metal rod that fits between the tappet and the rocker arm. Its function is to transmit cam lobe lift to the rocker arm assembly. The rocker arm is nothing more than a lever. Its function is to convert the up wardmotion of a pushrod into downward motion that compresses the spring and opens the valve.
