Ignition Cartridge

An ignition cartridge, also known as an ignition module or ignition control module, is an electronic device used in automotive ignition systems. It is responsible for controlling the timing and firing of the spark plugs in the engine.

The ignition cartridge works by receiving signals from various sensors in the engine, such as the crankshaft position sensor and the camshaft position sensor. Based on these signals, it determines the optimal timing for the spark plugs to ignite the air-fuel mixture in the combustion chamber.

The ignition cartridge also regulates the voltage supplied to the ignition coil, which generates the high voltage needed to create a spark at the spark plugs. By controlling the timing and voltage, the ignition cartridge ensures that the engine runs smoothly and efficiently.

In some vehicles, the ignition cartridge is a separate component that can be replaced independently. In others, it is integrated into the engine control unit (ECU) or the distributor. If the ignition cartridge fails, it can cause issues such as misfires, poor fuel economy, and difficulty starting the engine.

It is important to regularly maintain and replace the ignition cartridge as recommended by the vehicle manufacturer to ensure proper engine performance and reliability.
