Abstract
A method for producing a cylinder block for an internal combustion engine having a sealing surface on which a gasket is mounted, a number of cylinder bores arranged side by side, each cylinder bore opening to the sealing surface, a water jacket surrounding the cylinder bores, and a cooling passage located between the cylinder bores. A liner assembly is first formed by joining a set of cylinder liners with each other side by side. At least one of the liners has a recess that forms a space located between adjacent cylinder liners when the liners are joined. A cast body having the water jacket is molded by pouring molten metal into a mold after the liner assembly is positioned in the mold. The molten metal is prevented from entering the space during the molding process. The space is communicated with the water jacket to form the cooling passage.
