It seems like such a small thing—that tiny area approximately 0.040 of an inch wide inside each combustion chamber. That area we're talking about is the gap between the electrode and strap on each ...

When General Motors introduced the High Energy Ignition (HEI) distributor in the mid-1970s, it was revolutionary. So much so that it still has a strong following among today's hot rodders. Like other ...

And there's a lot that you can do with only the simplest of tools (Fig. 1) to see that your distributor is in top condition. Think of your distributor as an infinitely accurate electric switch. It is.

How can you say "no" to simplicity, reliability, and an increase in power? Yeah, neither could we. Our old '75 Dodge workhorse with a 440ci engine (the Lawg) was still running the factory ignition ...

The ignition system is a glutton for punishment. As the miles rack up, the distributor wears out, the coil gets abused, and the spark plug wires melt. The steadfast ignition system only gets attention ...

Engines need spark plugs to burn their air/fuel mixture, and the spark plugs need a jolt of electricity to do their work. Older cars with conventional distributor-based ignition systems did it by ...

Q. I've noticed my new car doesn't have a distributor or spark plug wires, unlike every other car or truck I've ever owned. Can you explain how this works? A. This is one of the neatest automotive ...

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 ...

This animated film "Spark In The Firing Line" provides an in-depth look at the ignition system of modern motor vehicles, focusing on the role of spark plugs in igniting fuel within the combustion ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...
