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 ...

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 ...

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?).

We may receive a commission on purchases made from links. Is your car misfiring, having trouble starting, or idling rough? Are you wondering if the problem is one of your coil packs? If you're like ...

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, ...

Back in the day, point-triggered ignition system tune-ups were routine and happened roughly every 12,000 miles, along with a set of spark plugs and an ignition timing adjustment. These days, we’re so ...

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 ...

Just like spark plugs, ignition coils can wear down and become faulty over time. There are many common signs that an ignition coil is getting bad, but one obvious sign is an engine misfire, typically ...

Ignition coils play a crucial role in a vehicle’s ignition system. They serve to convert the battery’s low voltage into the high voltage necessary to fire the spark plugs. If there’s any malfunction ...
