摘要： A core unit for use in casting a cylinder block of an internal combustion engine which core unit comprises a preformed cylinder liner which includes a cylindrical sidewall defining an interior bore and having a port in the sidewall. A first core unit is formed of a reducible material molded upon the preformed liner, which first core unit includes a first main core portion which partially occupies the bore and a port core portion which extends through the port. A second core unit is formed of the reducible material separately from the first core unit and is assembled upon the cylinder liner, which second core units includes a second main core portion in the bore and in mating alignment with the first main core portion, thereby forming a composite core assemblage. The composite core assemblage is placed into a cylinder block mold, and molten metal is caused to enter the cylinder block mold, thereby forming a cylinder block surrounding the composite core assemblage. The reducible material of the first and second core structures is then reduced to open the interior bore and the associated port, thereby forming a cylinder block having a cast body portion in which the cylinder liner and associated exhaust and transfer passages are all integrally cast.
