What are the two major tasks performed by an ignition system?

The two major tasks performed by an ignition system are generating a high-voltage spark to ignite the air-fuel mixture in the engine's combustion chamber and ensuring the precise timing of this ignition event for optimal engine performance. The system typically consists of components like the ignition coil, distributor, and spark plugs, which work together to create and deliver the spark at the right moment during the engine's cycle. Proper functioning of the ignition system is crucial for efficient combustion and overall engine efficiency.
