ABSTRACT:
A two cycle engine has oil distribution means through the cylinder wall to feed internal oil passages in the associated piston that distribute oil directly to the skirt and cylinder walls, preferably between ports, and/or to the wrist pin and connecting rod bearing to thereby limit oil carryover into the engine charging and scavenging air.
