An ignition system is a crucial component in internal combustion engines, responsible for igniting the air-fuel mixture within the engine's cylinders. It typically consists of several parts, including the spark plug, ignition coil, and distributor. When the engine is running, the ignition system generates a high-voltage spark that ignites the fuel, enabling the engine to produce power. Modern ignition systems can be either conventional or electronic. Conventional systems use mechanical components to time the spark, while electronic systems utilize sensors and computer controls for more precise ignition timing. This advancement improves engine efficiency, performance, and emissions control.
