what do ignition coils do
Basics to High Performance. The job of an ignition system is to generate the spark energy needed to ignite the air/fuel mixture in an engine's cylinder. The main components of this system consist of an ignition coil, coil driver, distributor, spark plug wires, and spark plugs. This page will concentrate on the generation of the high voltage needed to produce a spark, and will begin with a basic ignition style and progress to performance types. Magnetos.
