ABSTRACT:
An ignition system for igniting fuel within an engine, comprising at least one ignition plug disposed in the engine, wherein the ignition plug has a pair of electrodes. A high voltage generator is connected to the ignition plug for applying a gated high voltage high frequency AC signal across the pair of electrodes so as to initiate ionization of the air/fuel mixture and create an infant plasma channel between the pair of electrodes. A plasma arc current generator is connected to the ignition plug for generating a predetermined magnitude of alternating current for a predetermined period of time so as to sustain the plasma channel and ignite the fuel, and a controller is provided for selectively enabling and disabling the high voltage generator and the plasma arc current generator at predetermined times.
