Car Ignition Parts
The mainly working principle of the automobile ignition system is ignition coils and spark plugs.
An ignition coil can generate a high voltage enough to ignite a spark between the spark plug electrodes. Both the primary coil and the secondary coil surround the iron core. The number of turns of the secondary coil is approximately 100 times that of the primary coil. One end of the primary coil is connected to the igniter, and one end of the secondary coil is connected to the spark plug. The other end of each of the two coils is connected to the battery.
When the engine is running, according to the ignition timing signal (IGT) output by the engine ECU, the battery current flows to the primary coil through the igniter. As a result, magnetic lines of force are generated around the coil, which contains a magnetic core in the center.
