How Does A Capacitor Discharge Ignition Work

A capacitor discharge ignition is an electronic ignition device that stores an electrical charge and then discharges it through an ignition coil in order to produce a powerful spark from the spark plugs in a petrol engine. Capacitor discharge ignition cdi or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors motorcycles lawn mowers chainsaws small engines turbine powered aircraft and some carsit was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition idi systems.
