Abstract:
A pin including recesses extending longitudinally between opposite ends, and a piston assembly including the pin, for a two-stroke engine, is provided. The recesses preferably have a radius of curvature less than a radius of curvature of the remaining outer surface of the pin. The pin is rotationally fixed relative to the connecting rod. As the connecting rod swings back and forth during operation, some of the recesses rotate beyond the load bearing region of the pin joint where oil is located, allowing oil to fill the recesses. As the pin swings back, these recesses carrying the oil enter the load bearing region of the pin joint, transferring the oil with them. Preferably, at least one of the recesses aligns with an oil opening in the pin, which aligns with an oil hole in the connecting rod, to receive and distribute oil along the full length of the pin.

Claim (Index 17):
A method of manufacturing a piston assembly for a two-stroke internal combustion engine, comprising the steps of:\n disposing a pin in a first rod bore of a connecting rod; the pin extending longitudinally along a pin axis from a first pin end to a second pin end, the pin having an outer surface extending around the pin axis, the outer surface including a plurality of recesses and a cylindrical portion, the recesses being spaced from one another by the cylindrical portion, the cylindrical portion presenting a cylindrical shape, the recesses extending longitudinally between the first end and the second end, each of the recesses extending inwardly from the cylindrical portion toward the pin axis, and each of the recesses having a curved shape.
