Abstract: An ignition system improves an air-fuel-ratio, i.e., good mileage and lean burn without changing a gasoline engine structure significantly. The ignition system comprises an electromagnetic wave generator including a first output part and a second output part configured to output an electromagnetic wave, a discharge device comprising a booster and a discharger provided at an output side of the booster, the booster having a resonance structure configured to boost an electromagnetic wave inputted from the first output part so as to cause a discharge from the discharger, and an electromagnetic wave emitter configured to emit an electromagnetic wave inputted from the second output part. The electromagnetic wave generator decreases an output power from the first output part, while the electromagnetic wave generator increases the output power from the second output part when an amount of a reflected wave from the discharge device exceeds a predetermined value.

Abstract: To emit an electromagnetic wave at an appropriate timing from an electromagnetic wave emission device 30 attached to an engine 20 to a combustion chamber 10 of the engine 20 using an engine control device 13 that cannot output a control signal to the electromagnetic wave emission device 30. A signal processing device 40 is connected to the engine control device 13 that outputs an ignition signal for instructing an ignition device 12 of the engine 20 to ignite fuel air mixture in the combustion chamber 10 of the engine 20. The signal processing device 40, upon receiving the ignition signal, outputs to the electromagnetic wave emission device 30 an electromagnetic wave drive signal that determines based on the ignition signal an emission period, which is a period for the electromagnetic wave emission device 30 to emit an electromagnetic wave to the combustion chamber 10, so that an ignition operation is performed during the emission period of the electromagnetic wave.
