A magnet is attached to the engine’s crankshaft to time the voltage spikes, these spikes are fed directly into the spark plugs to cause ignition, this is why you don’t need a battery.

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 ...

A backfiring car is more than a noisy annoyance, it can mean problems with your engine. Here's what can cause engine ...

Most people think you can check a small engine’s ignition system by removing the spark plug and grounding it while cranking the engine and watching for a spark. Nope. That just confirms that the ...

Older vehicles with distributor-type ignition systems use ignition (or spark plug) wires to send electrical current from the distributor to individual spark plugs, with the timing based on their ...

The ignition system’s job is to ignite the air-fuel mixture in a gasoline engine. In addition to the spark plugs that spark in the combustion chambers, the ignition system consists of an ...

This enables greater efficiencies because less fuel is burned per cycle, but has the trade-off of being more difficult to ignite using conventional spark plugs. Not so with laser ignition ...
