ロック。Adjacent cylinder bores are made close to each other to connect the cylinder walls, and a water jacket is provided around the walls, while through bolt holes are provided for integrally tightening the cylinder head and the bearing cap for supporting the crankshaft. In the cylinder block in which a boss part is formed, a drill hole for a cooling water channel is formed by penetrating the connecting part of the cylinder wall from the side of the cylinder block, and a drill hole is formed coaxially with this drill hole between the side of the cylinder block and the boss part. A cylinder block for an internal combustion engine, characterized in that drill holes are formed with smaller diameters on the inner side of the cylinder block, and each of these holes of different diameters is plugged with a sealing plug.
