を特徴とする内燃機関のピストン。 In a piston of an internal combustion engine in which oil is injected from an oil jet to the inner wall surface of the piston, the oil relief hole has one end opening below the oil ring groove of the piston and the other end opening on the inner wall surface of the piston. An internal combustion engine characterized in that at least the opening of the oil relief hole in the inner wall surface area of the piston with which the oil injected from the oil jet collides is formed toward the downstream direction of the oil injected from the oil jet. piston.
