What are the components and working principles of an automotive ignition system?

[OMaddox]

An ignition system consists of a power source (battery or generator), ignition coil, distributor, spark plug, ignition switch, and control circuit. Principle: During engine operation, the breaker contacts continuously open and close. When the breaker contacts are closed, the current from the battery flows from the positive terminal through the ignition switch, the primary winding of the ignition coil, etc., and returns to the negative terminal of the battery. Relevant information is introduced as follows: The automotive ignition system is designed for spark-ignition engines to operate normally. It supplies the spark plugs with a sufficiently high-energy high-voltage current (approximately 15,000~30,000V) in the ignition order of each cylinder, enabling the spark plugs to generate a strong enough spark to ignite the combustible mixture.
