Capacitor discharge ignition (CDI) is one of the electronic ignition systems and is widely used in motorcycles, lawn mowers, chainsaws, small engines, turbine aircraft and some cars . In order to shorten the secondary voltage generation time of the ignition coil (high voltage coil) and make the ignition system more suitable for use on high-speed engines (such as small engines, motors racing and rotary motors), a capacitor is used to charge and store the required energy, and if necessary, current is released through the ignition coil in a single breath, causing it to generate electricity at high voltage to trigger the ignition of the spark plug.
Basic Principles
Most vehicles use induction discharge ignition systems (transistor ignition systems), which use batteries (or generators).urs) as power sources and use transistor circuits to convert voltage. Amplification is a method of cutting off the primary current to the ignition coil at the moment ignition is required, causing the magnetic field of the ignition coil to collapse, allowing the secondary coil to generate current. high voltage electricity. In the CDI system, the charging circuit charges the capacitor when the ignition trigger signal is transmitted to the CDI, it stops charging and discharges the capacitor, allowing the high voltage current stored in the capacitor to generate high voltage electricity. voltage for ignition. enough coil to trigger the ignition of the candle.
1. The hand rope is broken. If the hand rope is broken, you can replace it directly, which generally costs one or two yuan each.
2. Generator hand-operated plate buckle broke, hand-operated plate damagedwas replaced directly.
3. The hand-pulled plate is inelastic. The above is the reason why the gasoline engine cannot be fired but can be fired by opening the fire valve.
