Abstract
A method of firing a spark plug of an internal combustion engine includes 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 to an ignition coil and connecting the engine coil to the spark plug. The firing of the ignition coil mirrors the square waveform of AC power from the engine control module. A battery is connected to the engine control module.
