See full text

A lubricating mechanism of a pin connection pair of an internal combustion engine having a piston, a pin, and a connecting rod. The pin may be mounted in two pin seat portions of the piston such that the pin and one of the two pin seat portions form the pin connection pair. The lubricating mechanism may include a lubricating passage through which a lubricating medium is flowable and an oil outlet orifice communicating with the lubricating passage. The lubricating passage and the oil outlet orifice may be disposed in a piston top portion of the piston. An opening of the oil outlet orifice may face in an axial direction and may be disposed directly below a corresponding portion of the lubricating passage such that the lubricating medium is flowable via the opening directly to a gap defined between the connecting rod and a pin seat portion.
