Abstract
Official abstract text for this publication.
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.
