Patent attributes
An internal combustion engine has an internal combustion engine body formed with a combustion chamber and an ignition device that ignites an air-fuel mixture in the combustion chamber. 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 further has an electromagnetic (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 that switches the receiving antenna resonating to the EM radiation emitted to the combustion chamber from the EM wave-emitting device among the plurality of receiving antennas.
