What is a Volkswagen Ignition Coil?
What is an Ignition Coil?
An ignition coil is an integral component of the vehicle's ignition system. It works as a transformer to convert the car battery's low voltage to the high voltage needed to create an electric spark in the spark plugs. This spark ignites the air-fuel mixture in the engine's combustion chambers, starting the engine and keeping it running.
Ignition coils are typically made up of two coils of wire wrapped around an iron core – the primary coil and the secondary coil. When electricity flows through the primary coil, it creates a magnetic field. When the current is interrupted, the magnetic field collapses, inducing a high voltage in the secondary coil. This high voltage is then channeled to the spark plugs.
In modern vehicles, ignition coils are more crucial than ever. With advancements in engine technology, the demand for precise and efficient ignition has increased. Efficient ignition coils contribute to better fuel economy, lower emissions, and improved engine performance. They are more crucial in vehicles with “coil-on-plug” ignition systems, where each spark plug has its own coil.
