Distributors used to be a fixture on car engines, but they were replaced by coil packs somewhere in the 1980s. Here's why ...

The ignition system’s job is to ignite the air-fuel mixture in a gasoline engine. In addition to the spark plugs that spark in the combustion chambers, the ignition system consists of an ignition coil ...

The purpose of the ignition system is to ignite, or fire, the spark plugs in order to generate power to run the engine. Most vehicles built prior to 1974 use a non-electronic distributor ignition ...

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, ...

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 ...

For optimum engine performance, it is necessary to have an ignition system that is on point. You see the whole purpose of your ignition system is to transform your battery's low voltage into the ...

Out of the many different aspects of the Pontiac hobby, ignition-system function is often the most misunderstood. Since it deals with an intangible (i.e., electricity), it's very easy to assume one ...

Over the past few years, we have run across some teams who, for the goal of attaining maximum power, chose to run without an alternator. We started thinking about that and decided to see if there were ...

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 ...

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 ...
