The objective of the present invention is to increase the propagation velocity of flames in an area near the outer periphery of a combustion chamber in an internal combustion engine which is provided with an internal combustion engine body in which a combustion chamber is formed, and an ignition device for igniting an air-fuel mixture in the central part of the combustion chamber, and in which a combustion cycle is repeated in which the air-fuel mixture is ignited by the ignition device and combusted. The internal combustion engine is provided with: an electromagnetic wave radiation device for radiating electromagnetic waves from a radiating antenna to the combustion chamber; a receiving antenna, which is provided on the partition member, to the portion of the partition member (piston) partitioning the combustion chamber, said partition member partitioning an area near the outer periphery of the combustion chamber, and the antenna resonating with the electromagnetic waves radiated from the radiating antenna to the combustion chamber; and a control device, which controls the electromagnetic wave radiation device such that the electromagnetic waves are radiated from the radiating antenna to the combustion chamber during the propagation of the flames, after the air-fuel mixture has been ignited by the ignition device. |
