ン構造。 A partition is provided to divide the cooling water passage surrounding the cylinder of the cylinder block body into a first water passage near the cylinder head side and a second water passage near the crankcase side, and the cooling water is directed to the first water passage side. A forced convection section for forcing the cooling water to flow is formed, and a natural convection section for natural convection of the cooling water is formed on the side of the second water channel, and the depth of the forced convection section is set such that the depth of the forced convection section is set on the cooling water inlet side of the cooling water passage. An engine structure characterized by a structure that is gradually deepened from the top to the cooling water outlet side.
