Capacitor discharge ignition (CDI) systems operate on the principle of efficiently charging and discharging a capacitor. This system is designed to provide a rapid burst of energy to the ignition coil, causing the spark plug to spark and start the engine. Let's dive into each step to better understand how this happens in real-time.
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, gas turbine -powered aircraft, and some cars.
The capacitive-discharge ignition uses capacitor to discharge current to the ignition coil to fire the spark plugs. The history of the capacitor discharge ignition system can be traced back to the 1890s when it is believed that Nikola Tesla was the first to propose such an ignition system.
Capacitor discharge ignition systems (CDI) are mainly divided into two types: alternating current CDI (AC-CDI) and direct current CDI (DC-CDI). Each type has its specific working principles, suitable environments, and user experience. Below, we explore these differences more practically.
On the other hand, capacitors in CDI systems are used to store and swiftly release electrical charge at the right moment for ignition. Despite their differences, both are essential for the ignition process.
No, ignition coils and capacitors serve different functions in an ignition system. An ignition coil transforms low voltage, often from a battery, into the thousands of volts needed to create an electrical spark in the spark plugs for igniting the engine's fuel mixture.
