Exploring the Capacitor Discharge Ignition System Diagram
The capacitive discharge process stores energy in a capacitor and then releases it rapidly, creating a high-voltage spark that can reliably ignite the air-fuel mixture in any operating condition. This ensures a more efficient combustion process, leading to improved engine performance, better fuel efficiency, and reduced emissions.
