Working principle a CDI System

A capacitor discharge ignition works by passing an electrical current over a capacitor. This type of ignition builds up a charge quickly. A CDI ignition starts by generating a charge and storing it up before sending it out to the spark plug in order to ignite the engine.This power passes through a capacitor and is transferred to an ignition coil that helps boost the power by acting as a transformer and allowing the energy pass through it instead of catching any of it.Capacitor Discharge Ignition consists of several parts and is integrated with the ignition system of a vehicle. The foremost parts of a CDI include the stator, charging coil, hall sensor, flywheel and the timing mark.
