What is the ignition in the car do?

The ignition in a car is responsible for starting the engine by igniting the air-fuel mixture in the combustion chamber. It typically involves an ignition coil that generates a high-voltage spark, which is sent to the spark plugs. When the spark plugs fire, they ignite the fuel, allowing the engine to run. Additionally, the ignition system controls the timing of the spark to ensure optimal engine performance.
