ンの冷却構造。 A piston cooling structure for an internal combustion engine having a single piston pin boss protruding from the inner wall of the top of the piston and disposed in a piston pin receiving part at an upper end of a connecting rod. It has a cup shape that surrounds the pin boss part, and has a communicating passage that opens between the crankshaft receiving part at the lower end of the connecting rod and the piston pin receiving part, and the connecting passage is provided in the crankshaft receiving part through the back side of the Atsuppa bearing metal. and a lower oil passage passing through the sliding surface side of the lower bearing metal and communicating with the oil passage of the crankshaft, so that the atupa oil passage and the lower oil passage communicate with each other. Cooling structure for internal combustion engine pistons.
