したことを特徴とするエンジン構造。 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 to be deeper in the area between the cylinders and deeper in the area between the cylinders. The engine structure is characterized by a shallow center section.
