A plasma ignition system has an electromagnetic noise reduction circuit in addition to a discharge power circuit, a plasma generating power circuit, a plasma ignition plug, a discharging wire and a plasma generating wire. The noise reduction circuit includes a first rectifier connected to the discharging wire, a second rectifier connected to the plasma generating wire, and a noise reducing capacitor connected in parallel to the second rectifier. The noise reduction circuit is disposed close to the ignition plug so that the noise reducing capacitor bypasses only high frequency noise currents generated when the ignition plug discharges. |
