  • Crankcase-scavenged engine
    Patent number: 4088097
    Abstract: An internal combustion, reciprocating-piston engine which includes a sealed crankcase for inducting and compressing air or an air-fuel mixture into the engine. The compressed gas is then forced into a holding tank for subsequent induction into the cylinder combustion chamber. This pre-compresses or "supercharges" the fuel mixture before compression by the piston. An enclosed lift tube within the connecting rod is provided for conveying lubricating oil through the crankcase to the cylinder walls.
    Type: Grant
