If your spark plugs are worn out, it forces the ignition coils to operate at a much higher output. Keeping your spark plugs in optimum condition can reduce your chances of experiencing an ignition coil failure. Some simple regular maintenance will save you a lot of money in the long run.

An ignition coil is a key component in a vehicle's ignition system. Generating thousands of volts, the ignition coil sends energy in the form of an electric spark to the spark plugs. This spark is what is used to ignite the air and fuel mixture and start the engine and keep it running. In early automobile designs, a single ignition coil was used to create the spark for all of the engine's spark plugs—modern engine designs use a separate coil on plug ignition coil system. This means that each spark plug in the engine has its own ignition coil mounted on the valve cover which powers only the one spark plug.

Points-type ignition systems used a set of breaker points to determine when the ignition coil would send its electric charge to the spark plugs. Modern ignition timing is controlled by the vehicle's computer system, which is controlled by a computer program. Performance-enhancing chips that reconfigure the computer's programming can be purchased and installed. This alters and creates new timing parameters as well as fuel mixtures and shift points to create a more performance-orientated vehicle.

The coil is a simple device - essentially a high-voltage transformer made up of two coils of wire. One coil of wire is called the primary coil. Wrapped around it is the secondary coil. The secondary coil normally has hundreds of times more turns of wire than the primary coil.Current flows from the battery through the primary winding of the coil.The primary coil's current can be suddenly disrupted by the breaker points, or by a solid-state device in an electronic ignition.If you think the coil looks like an, you're right - but it is also an inductor. The key to the coil's operation is what happens when the circuit is suddenly broken by the points. The magnetic field of the primary coil collapses rapidly. The secondary coil is engulfed by a powerful and changing magnetic field.

This field induces a current in the coils - a very high-voltage current (up to 100,000 volts) because of the number of coils in the secondary winding. The secondary coil feeds this voltage to the distributor via a very well insulated, high-voltage wire.Finally, an ignition system needs a distributor.
