| 摘要 |
This internal combustion engine (10) has an ignition device (12) that ignites an air-fuel mixture more forcefully than a spark discharge in a combustion chamber (20), wherein the discharge of unburned fuel is reduced and the fuel economy of the internal combustion engine (10) is improved. The internal combustion engine (10) is provided with an internal combustion engine body (11) with the combustion chamber (20) formed therein, and the ignition device (12) that ignites the air-fuel mixture in the combustion chamber (20) more forcefully than a spark discharge, as well as an electromagnetic-wave radiation device (13) that radiates, from an antenna (41), electromagnetic waves supplied by an electromagnetic-wave oscillator (32). The electromagnetic-wave radiation device (13) radiates electromagnetic waves from the antenna (41) and forms an electric field that increases the propagation speed of a flame. |
