Claim:
1. An internal combustion engine comprising: an internal combustion engine main body formed with a combustion chamber; and an ignition device that ignites fuel air mixture in the combustion chamber, the ignition device comprising (i) an ignition plug that includes an ignition side electrode exposed toward the combustion chamber to generate a spark discharge, and (ii) a plasma generation part that supplies electric energy to the spark discharge at the ignition side electrode, thereby generating high intensity plasma from the spark discharge, wherein the internal combustion engine repeatedly carries out a combustion cycle, in which the ignition device ignites the fuel air mixture so as to combust the fuel air mixture, the internal combustion engine further comprises an electromagnetic wave emission device provided with an electromagnetic wave oscillator that oscillates an electromagnetic wave, and an antenna that emits the electromagnetic wave supplied from the electromagnetic wave oscillator to the combustion chamber, the electromagnetic wave emission device emits the electromagnetic wave from the antenna so as to create an electric field for accelerating a propagation speed of a flame, and the internal combustion engine further comprises:
