とを特徴とする、エンジンの冷却装置。 In an engine in which the side surface of the cylinder head is located outward from the contact surface between the cylinder head and the cylinder block, the cooling water passage of the cylinder head is connected between the exhaust port and the cylinder head deck surface.
The cooling water passage extends from the contact surface to the non-contact surface to the vicinity of the valve seat of the exhaust valve, and the thickness between the bottom of the cooling water passage and the cylinder head deck surface is the same as that of the contact surface and the non-contact surface. An engine cooling device characterized in that the contact surface is made thicker than the non-contact surface.
