8-STROKE INTERNAL COMBUSTION ENGINE

摘要

Abstract: The present invention concerns an 8-stroke internal combustion engine. Soon after 4 strokes for fuel combustion, the combustion gas is recirculated then water is sprayed thereon in the state of intake and compression of the combustion gas again into the cylinder block. Therefore, 4 strokes for the fuel combustion and, 4 strokes for vaporization and volume expansion of the sprayed water are alternatively repeated and high efficient power generation is enabled.
