What is the structure and working principle of the ignition system?

The ignition system consists of power supply, ignition coil, distributor, spark plug, ignition switch and control circuit. The principle of the ignition system is to make the contacts of the circuit breaker constantly open and close during the running of the engine. When the contacts of the circuit breaker are closed, the current of the battery starts from the positive pole of the battery and flows back to the negative pole of the battery through the ignition switch and the primary winding of the ignition coil. Classification of ignition system: 1. Traditional ignition system: the power supply is battery, and the voltage is 12V or 24V. The ignition coil and the circuit breaker * * * together generate a high voltage above 10000 volts ... which is divided into primary loop and secondary loop. The ignition coil is actually a transformer, which is mainly composed of a primary winding, a secondary winding and an iron core. 2. Electronic ignition system: The electronic ignition system has strong capability and reliable ignition.
