The ignition coils in your car provide the high voltage electrical current that allows your spark plug to create its spark. These parts are humble looking, and they make use of relatively simple ...

Okada Projects of Japan recently introduced an innovative, highly effective and easy-to-install ignition Plasma Direct system, replacing the factory coils while promising to increase both horsepower ...

It's easy to forget about maintenance intervals, even for car people like us. Believe it or not, non-moving parts do wear. Maybe not as fast as moving parts (serpentine belts, brake rotors, and so on) ...

High-voltage experimenters have been using automotive ignition coils to generate impressive sparks in the home lab for decades, and why not? They’re cheap, easily obtainable, and at the end of the day ...

Newer engines like as the Coyote, LS, and G3 Hemi have an ignition coil for each cylinder. This modern approach is called "coil near plug" or CNP, and it replaces the distributor with eight small ...

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 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. I’ve always thought it would be funny to build scale-size ...

The ignition control module is a crucial component of a vehicle's ignition system. It is a control unit responsible for regulating the ignition timing and generating sparks to ignite the fuel-air ...

Precise ignition timing is essential for high-performance engine tuning and ensuring your small-block or big-block is delivering every horsepower within its capability. Since the era of poodle skirts, ...

The spark plug was a key invention in the history of the internal combustion engine, allowing combustion to be easily controlled and engines to rev faster than messy earlier designs. Mid-century cars ...

I have had to replace a number of the ignition coils on my VZ Commodore wagon over the last six months. The “check power train” warning alert activates and the car starts running roughly. Six months ...

Combustion requires three elements - fuel, air and an ignition source. Air is a no-brainer, being available pretty much wherever drivers are. For most of the history of the automobile we've mainly ...
