Abstract: To alleviate or eliminate a problem of unburned fuel discharged to the outside of a cylinder in a case in which an air fuel mixture is insufficiently combusted in a combustion chamber. During the expansion stroke in which a high voltage is applied to an ignition plug via an ignition coil, and a spark discharge is caused to occur at the ignition plug, thereby the air fuel mixture in the combustion chamber is ignited and combusted, in a case in which deterioration of combustion state is detected, a microwave electric field is created in the combustion chamber prior to an opening timing of an exhaust valve at an end stage of the expansion stroke, thereby plasma is generated and enlarged in the combustion chamber.

Abstract: It is configured such that plasma generated at a time of ignition should diffuse over an entire combustion chamber in a spark ignition type internal combustion engine in order to improve fuel efficiency. An ignition device for a spark ignition type internal combustion engine is provided including an ignition plug and a transmission antenna provided in the vicinity of the ignition plug and adapted to transmit an electromagnetic wave to a combustion chamber. The ignition device allows a spark discharge generated between a central electrode and a ground electrode of the ignition plug to react with an electric field created via the transmission antenna in the combustion chamber so as to generate plasma and ignite fuel air mixture. A receiving antenna is arranged on a combustion chamber -facing surface of at least one of an intake valve and an exhaust valve, and is adapted to receive the electromagnetic wave transmitted from the transmission antenna.
