Ignition Coil is (also called a spark coil) an induction coil which is used to increase the low voltage of the battery (12 Volt) to A very high voltage (About 50000 Volt) to produce spark within the engine cylinder for the combustion of fuel. It is used in the automobile ignition system. We can also say that it is a short step-up transformer. Working Principle Ignition coil mainly consists of the primary winding, Secondary winding and an iron core. When the current through the primary winding Makes and breaks repeatedly by contact breaker, It induces a very high voltage in the secondary winding (About 50000 V). This high voltage from the secondary winding is transferred to the Spark plugs through … Continue reading Ignition Coil – Main Parts, Working Principle and Application
