Just remember a capacitor takes time to charge (and discharge). 1. DISCHARGING A CAPACITOR. The discharge time for a capacitor is exactly the same as the charge-time. If it take 5 seconds for capacitor to charge from 1v to 7v, it will take 5 seconds to discharge back to 1v. The discharge curve is shown in the following …
OverviewHistoryThe basic principleSimilar Non-CDI Ignition SystemsAdvantages and disadvantages of CDI
Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making t…
