ABSTRACT:
A plasma ignition system includes an ignition plug attached to an engine and having a center electrode, a ground electrode, and a discharge space, a discharge power source circuit, a plasma generation power source circuit, a resistance element between the discharge power source circuit and the center electrode, a rectifying device between the plasma generation power source circuit and the center electrode, and an element receiving portion in a periphery of the center electrode. The plug puts gas in the discharge space into a plasma state to ignite a fuel/air mixture in the engine, as a result of application of high voltage to the plug by the discharge power source circuit and supply of high current to the plug by the plasma generation power source circuit. The resistance element and the rectifying device are placed in the receiving portion.
