Abstract
A method of firing at least one spark plug of an internal combustion engine include supplying AC power to the spark plug in which the AC power has a waveform with a rising edge and a falling edge, activating the spark plug during the rising edge of the waveform, and deactivating the spark plug during the falling edge of the waveform. This method further includes connecting an engine control module and a vehicle power supply to at least one AC ignition coil and connecting the AC ignition coil to the spark plug or spark plugs. The firing duration of the AC ignition coil or transformer mirrors a digital square waveform duration from the engine control module.
