Exploring the Capacitor Discharge Ignition System Diagram
When the trigger module receives the electrical pulse from the stator, it triggers the discharge phase, allowing the capacitor to quickly discharge its stored energy into the ignition coil. This creates a high-voltage spark that is sent to the spark plug to ignite the air-fuel mixture in the combustion chamber.
