Ignition coils last far longer than spark plugs and only need replacement when symptoms appear. Here’s how to tell if coils ...

This article deals with flame rectification as it applies to direct spark ignition (DSI) modules. They are manufactured by a few different companies — Fenwal, Honeywell, Robertshaw, and White Rodgers, ...

In conventional engines, spark plugs send high-voltage electricity sparking across the electrode gaps in a combustion engine: This results in a controlled explosion in the engine, which drives the ...

Learn how to use dielectric grease on spark plug boots to prevent voltage leaks and corrosion. Follow our guide to protect ...

The pollutant emissions and high-energy consumption of combustion engines using conventional spark plugs have long been serious environmental problems. Now, it has been demonstrated that lasers can ...

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 ...

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 ...

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 ...

Some four-cylinder engines use eight spark plugs for better fuel economy, efficiency, and emissions, though they can be ...

Yesterday at the Tokyo Motor Show, Mazda released new info on its highly anticipated compression-ignition Skyactiv-X engine. It's all a bit daunting if you're not an engineer, but helpfully, Mazda put ...
