It mainly consists of the battery, ignition switches, ignition coils and spark plugs and other components. Battery ignition system supplying power required. Ignition switch is turned on or off the ignition system power. Ignition coil ignition energy storage, and battery voltage into a high voltage ignition. Distributor and spark advance by the breaker mechanism and other components. Breaker function is switched on or off the ignition coil primary circuit; distributor's role is to generate the ignition high voltage ignition coil, delivered to each cylinder spark plug in accordance with the working order of the engine; the role of institutions is to spark advance with the engine speed, load and gasoline octane adjust ignition timing changes. High voltage ignition spark plug into the cylinder combustion chamber and spark between the electrodes ignite the mixture.
