Unlike older vehicles, which needed ignition tune-ups at least once a year, most vehicles on the road today have electronic ignition systems that are built to go for years without the need for them.

The purpose of the ignition system is to ignite, or fire, the spark plugs in order to generate power to run the engine. To do so, the battery sends current to the ignition coil. Then that high voltage ...

ABSTRACT A series of ignition systems were evaluated for their suitability for high-EGR SI engine applications. Testing was performed in a constant-volume combustion chamber and in a single-cylinder ...

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 ...

When you’re trying to learn about older cars, you might as well be signing up for the debate club. Every question, especially when it comes to breaker points, electronic, and multiple spark discharge ...

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.

At 7,000 rpm, a spark plug ignites the air/fuel mixture nearly 60 times per second. Any one of those 60 sparks going amiss can at best be mildly annoying, and at worst cost you a race or an engine.

Corvettes have had electronic ignition systems for over 40 years, starting with the powerful, dependable Delco HEI (high energy ignition) system in 1975 models. Prior to that, nearly all Corvettes, ...

The Mopar electronic ignition system introduced in 1972 was cutting edge in its day. While everyone else was using the ancient points-type ignitions, Chrysler scooped 'em all with the electronic unit.
