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 ...

[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower ...

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?).

The P0351 code means your engine control module (ECM) has detected a malfunction in the ignition coil “A” primary/secondary circuit, which corresponds to cylinder 1 on most engines. When this circuit ...

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, ...

Around 1975, General Motors made a significant advancement in stock passenger ignition technology: the High Energy Ignition (HEI). One of its major features was installation simplicity. The coil was ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

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 ...

Ignition coils play a crucial role in a vehicle's ignition system as essential components that facilitate the engine's combustion process. They are responsible for converting the low voltage supplied ...

The ignition is easily the most misunderstood system in any car. Most enthusiasts treat ignitions like some sort of weird, black magic/voodoo curse best left alone until it fails. Either that or they ...

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 ...
