Abstract
A method of manufacturing cylinder blocks. A cylinder block includes cylinder liners, the number of which corresponds to the number of cylinders in the engine, and a block body molded integrally with and about the cylinder liners. A liner assembly is formed by aligning cylinders in a single row and connecting the adjacent cylinder liners. A variable section provided between each pair of cylinders enables the distance between the axes of the outer cylindrical surface of each cylinder liner to be varied. The block body is molded by first arranging the liner assembly in a mold. Molten metal is then charged into the mold. When the metal solidifies, the block body is formed encompassing the liner assembly. A reference point on the block body is used to machine the inner cylindrical surfaces and form the cylinder bores.
