ABSTRACT:
It is a reciprocating type of internal combustion engine, of which the inside of piston is furnished with a gasifying chamber; the outlet of the gasifying chamber can, during the piston moving reciprocatingly, be in alignment with the spraying nozzle on the cylinder and the third scavenging passage in sequence so as to let the spraying nozzle directly spray fuel into the gasifying chamber, and to let the fuel absorb the high temperature heat of the piston top to cause the fuel to be gasified completely. The gasified fuel flows into the third scavenging passage during the piston moving downwards and is to be stored therein temporarily; then, the gasified fuel is compressed into the cylinder by means of the compressed air in the crankcase so as to mix with the fresh air entered into the cylinder via other scavenging passages. The gas mixture is to be compressed with the upward moving piston, and to be exploded to generate a mechanical power.
