The capacitor stores electrical energy and releases it quickly to generate a high-voltage spark. The ignition coil steps up the voltage from the capacitor to the required level for the spark plug. The trigger senses the movement of the piston in the engine and sends a signal to the control unit. The control unit processes the signal and sends a pulse to the ignition coil, which charges the capacitor. When the capacitor is fully charged, the control unit discharges it through the ignition coil, creating a high-voltage spark at the spark plug, igniting the fuel mixture.
CDI systems are widely used in ATV engines because they provide a more reliable and efficient ignition compared to traditional breaker point ignition systems. They also offer increased engine performance, lower maintenance requirements, and improved fuel efficiency.
