成としたことを特徴とするピストン冷却装置。 In an engine that cools the piston by injecting lubricating oil pumped by an oil pump from an oil passage formed in a connecting rod, the oil passage in the connecting rod is arranged in the opposite direction to the direction of rotation of the crankshaft. The injection port of the oil passage is divided into two fork-shaped oil jets toward the back surface of the top of the piston and the piston skirt, and a variable check valve is provided to open and close the fork-shaped oil jet. Features a piston cooling device.
