Abstract

PURPOSE:To carry out effectively the cooling between cylinders, by inserting the cooling pipe between cylinders with casting. CONSTITUTION:A S-shape cooling pipe 4a, 4b made of anticorrosive alloy having an inlet (a) and an outlet (b) is formed. When a crank-case 1 core (sand-mold) is casted, the cooling pipe 4a, 4b is set through that its center is on the center line X-X on the direction of the crank shaft, a half of the pipe is around one cylinder 2 and other half of the pipe is around other cylinder 2 between cylinders 2, 2, for making X- shape in the whole. The pipes are casted between cylinders 2, 2 in a body at the same time of casting the crank-case 1. Thereby the cooling water in the cooling jacket 3 flows to the direction of arrow W, when the case 1 and the cylinder 2 are cooled, the cooling water flows into the cooling pipe 4a, 4b from the inlet (a), flowing positively, flowing out of the outlet (b), cooling between cylinders around the center line X-X to the direction of the crankshaft.
