Ignition came from a word ignite which means to set on fire. This system provides spark by the use of spark plug to burn the air and fuel mixture in the combustion chamber of an engine. The system operates by transforming 12 volts battery power to thousands of volts, enough to produce spark at the spark plug gap.
Components of Ignition System
Battery is the source of electrical power. The battery continually supplies electrical power needed by the system.
Ignition switch control the ignition system and other electrical circuits. Also called an automobile main switch.
Ignition coil is a transformer type device that transform the 12 volts battery power to 30,000 up to 60,000 volts. The coil is composed of two winding, the primary and secondary winding.
Distributor assembly is a device that distribute high voltage to the different spark plugs. It has also mechanism that advances the delivery of spark when engine is at higher RPM. The distributor also shaft opens and closes the contact point.
Contact point closes and opens the primary circuit to the ground so that the ignition coil can increase the voltage supplied by the battery.
Condenser is a device that absorbs and reduce electric arc when contact point closes.
High Tension Cables is the high voltage path from ignition coil secondary terminal to distributor cap center tower to different spark plug.
Spark plug is the device installed at the engine body and deliver high voltage to the combustion chamber by spark to ignite the air and fuel mixture.
