PURPOSE:To suppress deformation of liner and reduce the man-hours for processing by casting cylinder liner made of cast iron of austenite type in the cylinder body of aluminum alloy in such a way as in a single piece. CONSTITUTION:A cylinder liner 3 made of cast iron of austenite type is cast in the cylinder body 2 of aluminum alloy in such a way as in a single piece. This lessens the difference in thermal expansion between the cylinder body and the cylinder liner, which ensures that the cylinder liner has less bore deformation at the time of cylinder cooling to lead to elimination of necessity for genuine roundness processing. |
