The ignition coil converts the vehicle’s 12 volts to the more than 10,000 volts required to produce an effective spark in the spark plugs, which in turn ignite the air-fuel mixture in an engine’s ...

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.

Sometime around 1975, General Motors made a significant advancement in ignition technology: the High Energy Ignition (HEI to you and me). Its best feature was simplicity. The coil was contained within ...

The ignition (or distributor) cap is where ignition wires that run to the spark plugs receive high-voltage current from the ignition coil. Metal contacts in the cap connect with contacts in the ...

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 ...

Combustion requires three elements - fuel, air and an ignition source. Air is a no-brainer, being available pretty much wherever drivers are. For most of the history of the automobile we've mainly ...
