Ignition Coils
Ignition coils are an essential component in automotive ignition systems, responsible for converting low voltage from the battery into the high voltage required to generate an electric spark in the spark plugs. This electromagnetic induction process enables the efficient combustion of air-fuel mixtures within the engine cylinders, ultimately powering the vehicle. Ignition coils are typically composed of a primary winding, a secondary winding, and a core made of iron or ferrite material to concentrate the magnetic field. The primary winding has fewer turns and is connected directly to the battery, while the secondary winding has thousands of turns and produces the high voltage required for spark generation. In modern vehicles, ignition coils are often integrated into individual ignition modules, which are responsible for controlling the precise timing and duration of the sparks generated in each cylinder.
