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 ...

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 ...

[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 ...

If you're a follower of the "How It Works" series, you've been learning the principles of what makes a car run. You've boned up on the four-stroke cycle, valvetrains, cooling, lubrication, and ...

Traditional aircraft magnetos, a WWII-era technology, are mechanical, have many moving parts prone to failure, and offer fixed settings and a weaker spark, leading to inefficient combustion.

Mazda took the industry by storm when earlier this month it announced plans to introduce gasoline-powered Homogeneous Charge Compression Ignition (HCCI) engines in 2019. HCCI engines are typically ...

The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

Here’s something you’re supposed to do about once every millenium or so on your trusty BMW Airhead – apply heat sink compound to the underside of the electronic ignition module. Thanks to Matt ...
