The role of the ignition system

The ignition system is an important part of the gasoline engine. The performance of the ignition system has a great influence on the engine power, fuel consumption and exhaust pollution. All equipment capable of generating an electric spark between the two electrodes of the spark plug is referred to as an engine "ignition system." It usually consists of a battery, a generator, a distributor, an ignition coil, and a spark plug.

When the gasoline engine is close to the top dead center, the combustible mixture is ignited by the spark plug, so that the combustion works externally. For this reason, the gasoline engine has a spark plug in the combustion chamber. The function of the ignition system is to generate an electric spark of sufficient energy between the two electrodes of the spark plug in accordance with the working sequence of the cylinder.
