It works on the principle of electromagnetic induction and consists of primary and secondary windings.
The primary winding is connected to the battery and is responsible for producing a magnetic field when the ignition switch is turned on. This magnetic field collapses when the ignition switch is turned off, which induces a high voltage in the secondary winding. This high voltage is then sent to the spark plugs via the distributor or ignition module.
The distributor or ignition module is another important component of the ignition system. Its main function is to distribute the high voltage sparks from the ignition coil to the correct spark plug at the right time. It does this by using a rotor and a set of contacts or cap and rotor assembly.
The rotor is connected to the ignition coil and rotates inside the distributor. As it rotates, it passes by the contacts or cap and rotor assembly, which are connected to the spark plugs. When the rotor passes by a contact or cap and rotor assembly, it sends a high voltage spark to the corresponding spark plug, causing the fuel-air mixture in the combustion chamber to ignite.
In addition to the ignition coil and distributor or ignition module, the ignition system also includes other components such as spark plugs, spark plug wires, and the ignition switch.
