Automotive Ignition Coil is used in modern engines to ignite the spark plug by generating high power from the working fuel

 

An automotive ignition coil is an electrical induction coil present in a vehicle’s main ignition system, utilized to convert the weak low voltage of the battery to high voltage required for the ignition of the vehicle. Automotive ignition coils play a crucial part in the smooth and efficient operation of the vehicle's engine. For instance, in September 2021, a major car maker in Germany, Mercedes-Benz, unveiled its newest S 680 Guard 4MATIC model which includes 12 ignition coils.

Automotive Ignition Coils is available in two forms, namely, a single conductive path and a multi-conductor. The single conductive path automotive ignition coil uses only one wire to produce a high voltage. On the other hand, the multi-conductor ignition coil uses two wires to generate a better voltage.

Today, there are many companies in the market offering high quality automotive ignition coils. The design of the ignition coil determines its suitability in providing high voltage to the vehicle. There are a few important factors that one must consider while choosing a high voltage automotive igniter.

There are many parts in an automotive ignition coil that need to work in unison to provide the necessary voltage to an electrical circuit. There are two types of parts in an ignition coil, namely primary and secondary coils. The primary coil is placed on the upper side of the engine ash chamber and the other one lies on the bottom side. The primary coil is the main connector for all voltage requirements while the secondary coil is used for testing and regulating the voltage. The automotive ignition coil also includes many turns of insulated conductors that allow power to pass through it easily from the battery to the primary coil.

The electric spark plug comprises the main components of the automotive ignition coil. There are various types of electric spark plugs available, and they vary in the amount of current delivered to the vehicle. While high performance units deliver high current, the medium duty units are used for normal vehicles and low voltage units are used for fleet vehicles.
