構造。 A cooling oil groove is formed on the outer peripheral surface of the liner, and when this liner is inserted into the bore of the cylinder block, a space defined by the inner peripheral surface of the bore of the cylinder block and the groove forms a cooling oil flow path, In the oil cooling structure of the cylinder, the cylinder is cooled by flowing cooling oil from top to bottom in this cooling oil flow path, and the cooling oil is discharged from a discharge path at the lower end of the cooling oil flow path to an oil pan. An oil cooling structure for a cylinder, characterized in that at least the lower part of the discharge passage at the lower end of the passage forms a straight passage parallel to the axis of the cylinder liner, and is oriented toward the main axis of a crankshaft disposed below.
