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?).

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 ...

One of the main differences in regular maintenance between a gasoline and a diesel-powered car is replacing the spark plugs. While diesel engines rely on compression to create ignition, and thus ...

At one time or another, we have all been stymied by a gas engine with either a no-start or a hard-start condition, or another performance issue that seems to elude logic. The engine has fuel, spark, ...

The ignition coil converts the vehicle’s 12 volts to the more than 10,000 volts required to produce an effective spark in the spark plugs, which in turn ignite the air-fuel mixture in an engine’s ...
