PURPOSE: To realize structure eliminating oscillation and noise of an engine and reducing output loss by providing a combustion chamber furnished with an injection nozzle symmetrically in the radial direction of the outside with a rotation output axis as its center.
CONSTITUTION: A fuel pump 2 to supply fuel, an air compressor 3 and a cooling water pump 4 are provided, and simultaneously, a speed reducer 5 and a cooling fan 6 are installed on a rotation output axis 9. Additionally, a compression and scavenging switch valve 14 for compression and scavenge strokes, an expansion injection and scavenge switch valve 17 for expansion injection and scavenge strokes, a fuel suction switch valve 18 for suction stroke and a fuel injection control valve 19 are respectively provided, and simultaneously, a rotary valve 15 to supply air for control to control switch valves 14, 17-19 of each process is provided. Thereafter, an ignition plug 13 to ignite air-fuel mixture is provided, the air-fuel mixture supplied to the inside of a combustion chamber 12 is ignited and burnt, and the rotation output shaft 9 is rotated by reaction force at the time of injecting combustion gas from an injection nozzle 16.
