| 摘要 |
The present invention is directed to an internal combustion engine for making suction, compression, explosion, expansion and exhaust strokes in an operating chamber of variable volume defined between a housing and a piston. The internal combustion engine includes: an independent combustion chamber of fixed volume, formed in the housing and provided with a fuel supply device, for independently producing combustion therein; at least one communication passage for communicating the independent combustion chamber with the operating chamber of variable volume; and a control valve for allowing introduction of compressed air from the operating chamber into the independent combustion chamber and providing injection of combustion gas from the independent combustion chamber into the operating chamber at specified timing. The internal combustion engine is configured to independently produce main combustion without communication with the operating chamber. Thus, the internal combustion engine can achieve a high compression ratio without causing damage to engine components due to knocking.
