An all-round connecting stay (6) is provided between the cylinder tubes (3-5) and the cylinder block housing (2), which divides the oil jacket and the cooling water jacket (7). The connecting stay in the area of the water jacket is provided with ribs (13,16) between the cylinder tube and the cylinder block housing, the height of which is less than 0.5 times the height of the cooling water jacket. In the area of the oil jacket, the connecting stay may also be provided with ribs between the cylinder tube and the cylinder block housing, the height of which is smaller than 0.5 times the height of the oil jacket. All the ribs are at least partly triangular and increase from the cylinder tube to the cylinder block housing.
