1. An internal combustion engine including an internal combustion engine body formed with a combustion chamber and an ignition device igniting an air-fuel mixture in the combustion chamber, wherein repetitive combustion cycles, including ignition of the air-fuel mixture by the ignition device and combustion of the air-fuel mixture, are executed, the internal combustion engine comprising:
an EM wave-emitting device that emits EM radiation to the combustion chamber, a plurality of receiving antennas located on a zoning material that defines the combustion chamber, where the antennas resonate to the EM radiation emitted to the combustion chamber from the EM wave-emitting device, and a switching means which switches the receiving antenna resonating to the EM radiation emitted to the combustion chamber from the EM wave-emitting device among a plurality of receiving antennas. |
