PURPOSE: A method of manufacturing a cylinder block for an engine is provided to improve contact among materials, settle a contact problem made by difference of thermal expansion coefficient, and prevent generation of defect in casting the cylinder block. CONSTITUTION: A method of manufacturing a cylinder block for an engine comprises steps of manufacturing an aluminium alloy cylinder liner, by a spray forming method(S1); installing the aluminum alloy cylinder liner in a metal mold for casting a cylinder block(S2); and casting the cylinder block by injecting aluminum alloy liquid metal under high pressure into the metal mold(S3). Since the cylinder liner of the same material, manufactured by the spray forming method is installed, contact among materials is improved.
