A method of manufacturing integrated aluminum liners for light engine blocks using hypereutectic Al-Si alloys is provided to obtain light-weighted compact engine structures, and enable the integrated cylindrical liners to be applied to both aluminum blocks and magnesium blocks by integrally manufacturing individual cylindrical liners using hypereutectic Al-Si alloys. A method of manufacturing an integrated aluminum liner for a light engine block using a hypereutectic Al-Si alloy comprises the steps of: providing an A390 alloy(Al-17%Si-4Cu) workpiece; manufacturing a mold having a cavity that is capable of forming a structure while outer diameter surfaces of four cylindrical liners for in-line 4 cylinder engines or three liners arranged at left and right sides of V6 type engines come in contact with one another; injecting molten A390 alloy(Al-17%Si-4Cu) into the cavity of the mold by gas pressure; and integrally manufacturing respective cylindrical liners by the mold to obtain an aluminum liner, and disposing the aluminum liner in an aluminum block high pressure casting equipment to integrally form the aluminum liner on an aluminum cylinder block.
