ABSTRACT:
An internal combustion engine includes a cylinder head, a cylinder having an opposed surface opposed to the cylinder head and including a water jacket, which is concave in an axial direction of the cylinder, and a piston provided in the cylinder. An oil ring is provided on the piston on a side that is farthest from the cylinder head. At least a portion between a cylinder inner surface and the water jacket in the cylinder is made of a material having a higher thermal conductivity than that of iron. A bottom wall of the water jacket is positioned in the cylinder axial direction between the opposed surface of the cylinder and a lower end of the oil ring when the piston is disposed at a top dead center position.
