An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...

A windings road:It all starts with the concepts of inductance and electromagnetism. Inside an ignition coil there are two sets of wire windings (aka coils, that's why it's called a "coil," get it?).

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

As long as there have been internal combustion engines, there has been a need for an ignition system to ignite the air and fuel mixture in the cylinders. From the earliest days of automotive ignitions ...

A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

Engines need spark plugs to burn their air/fuel mixture, and the spark plugs need a jolt of electricity to do their work. Older cars with conventional distributor-based ignition systems did it by ...

An ignition coil takes voltage from the battery and multiplies it to create a spark at the spark plugs, which in turn ignites the engine. Cars have been using some form of the coil ignition system for ...
