The Role Of The Car Ignition Coil

　　The function of the car ignition coil is to convert the 12V low-voltage electricity of the power supply into 15~20KV high-voltage electricity, and the high-voltage electricity is converted into a high-voltage electric spark through the spark plug to ignite the combustible mixture.

　　Working Principle of Ignition Coil Ignition coil is a part of the ignition system of the car. Its function is to generate high-voltage sparks to detonate the fuel mixture, which is beneficial to burn the fuel in the engine, and then generate energy to drive the car. The following is an introduction to the working principle of the ignition coil.

　　The working principle of the ignition coil is very simple and can be roughly divided into three steps. First, the power supply will generate voltage through the generator and send it to the two ports of the ignition coil. Then, the switch signal sent by the automobile ignition system will control the ignition coil to turn on the power supply for AC control. When the switch reaches a certain voltage, the ignition coil winding can generate high voltage. This AC control method is called "storage control". Finally, when the ignition coil is under a specific high voltage, the spark plug will generate sparks, detonate the fuel mixture through the spark plug, and prompt the car engine to ignite and start.

　　To sum up, the ignition coil is one of the key components in the automobile ignition system. Its working principle is: the voltage is generated through the generator, the switch signal controls the AC control on the ignition coil, and the ignition coil generates sparks under high voltage to detonate the fuel mixture. Prompt the car engine to start. The starting of the ignition coil is the basis of the automobile ignition system and an important guarantee for safe driving.
