Abstract
PURPOSE: To reinforce a core by inserting reinforcing materials to the top and under of the cooling water passages between cylinders as well as to improve cooling effect by narrowing the width of the cooling water passages.
CONSTITUTION: Reinforcing materials 12 made by bending platelike members of metals into a channel shape in section are inserted to the top end and bottom end outside circumferential faces of the cooling water passage portions 11 between the respective cylinders of a core 10 of a cylinder block. The strength of the portions 11 of the cooling passages, particularly the upper portions of thin wall thickness on account of draft are reinforced. Next, when casting is performed by using the above-described core 10, respective cylinders 13 are made respectively independent and the reinforcing materials 12 are inserted to the top and under of the outside wall surfaces of the cylinders 13, thus the cylinder block of extremely narrowed width of the passages 14 of cooling water is obtained.
