How Does Capacitor Discharge Ignition Work?
Capacitor Discharge Ignition Defined A capacitor discharge ignition is a type of ignition system used in both small and high-speed motors. They power motorcycles, lawnmowers, and some cars and aircraft. A capacitor discharge ignition uses a condenser, or capacitor, to discharge a quick jolt of electricity, which powers the spark plug and ignites the fuel in the cylinder. The Transformer Electric power flows from a car’s alternator into a step-up transformer. A transformer has two coils next to each other. When a moving current is applied to one coil, it creates a magnetic field that induces a current in the second coil. In a step-up transformer, the secondary coil has more turns than the primary. This increases the voltage. In the case of a capacitor ignition system, the transformer increases the voltage from about 12 volts to between 400 and 600 volts. Charging the Capacitor Electricity flows into a charging circuit, which charges a capacitor. A capacitor works like a very small batte
