What is Ignition Coil ?

Ignition coils are an electronic engine management component that are a part of the vehicle’s ignition system. The ignition coil functions as an induction coil that converts the vehicle’s 12 volts into the several thousand that are required to jump the spark plug gap and ignite the engine’s fuel mixture. Some ignition systems will use one coil to provide the spark for all of the cylinders, however most newer designs use an individual coil for each cylinder.

As the ignition coil is the component responsible for generating the engine spark, any problems with it can quickly lead to engine performace issues. Usually a faulty ignition coil will produce a few symptoms that can alert the driver of a potential issue.

How does an Automobile Ignition System Work?

The essential function of the ignition coil is the provision of high voltage, which jumps between the centre and earth electrode on the spark plug in the cylinder and thereby generates the ignition spark. In the process, the ignition coil plays an essential role in providing a reliable ignition and thus the smooth and efficient operation of the engine.

Symptoms of a Bad or Failing Ignition Coil:

Common signs include the Check Engine Light coming on, engine misfiring, rough idle, a reduction in power, and the car not starting.
