In a gasoline engine, the combustible mixture in the cylinder is ignited by an electric spark. For this purpose, a spark plug is mounted on the cylinder head of the gasoline engine, and the head of the spark plug extends into the combustion chamber. All devices that are capable of generating sparks between the spark plug electrodes on time are called ignition systems. The traditional ignition system consists of a battery, a generator, an ignition coil, a distributor, a spark plug, and the like. The conventional and conventional ignition systems are similar except that the distributor is replaced by electronic components. The electronic ignition type is all-electronic ignition system, completely eliminating the mechanical device, and the electronic system controls the ignition timing, including battery, generator, ignition coil, spark plug and electronic control system.
