How Does Car Ignition Work?

[LaZane]

The function of the ignition system is to supply the spark plug with high-voltage electricity of sufficient energy at the appropriate moment, according to the engine's operating state and sequence, to generate a spark between its electrodes, ensuring the ignition of the air-fuel mixture and enabling the engine to perform work. Below are the components of the ignition system: Hall Effect Distributor: The Hall effect distributor is a contactless distributor installed inside the distributor, consisting of a Hall trigger blade and an integrated circuit for generating Hall voltage. The window of the Hall trigger blade operates at the same speed as the camshaft. According to the Hall principle, the camshaft drives the trigger window, altering the magnetic field of the Hall element, which causes the Hall trigger to generate a weak voltage, known as the Hall voltage. Ignition Coil: The ignition coil is a transformer that produces the high voltage required for ignition. Generally, the ignition coils used in engine ignition systems can be divided into two types based on the magnetic circuit: open magnetic circuit and closed magnetic circuit.
