What is the principle of an ignition coil?

[JaceRose]

The principle of an ignition coil is: The working method of an ignition coil differs from that of a regular transformer. A regular transformer operates continuously, while an ignition coil operates intermittently, repeatedly storing and releasing energy at varying frequencies depending on the engine's speed. As automotive gasoline engines evolve towards higher speeds, higher compression ratios, greater power, lower fuel consumption, and reduced emissions, traditional ignition systems no longer meet the requirements. The core components of an ignition system are the ignition coil and the switching device. By increasing the energy of the ignition coil, the spark plug can generate sparks with sufficient energy, which is a fundamental condition for the ignition system to adapt to the operation of modern engines.
