Abstract
A method of die casting a cylinder block of aluminum wherein cylinder liners of another material are cast in. A cylinder insert component (14) is placed in the liner, leaving a gap (a) between the outer surface of the insert component and the inner surface of the liner. Pressurized aluminum melt flows against the outside of the liner and is allowed to flow into the gap via a passage (22) between the lower edge of the liner and a lower insert component (15), so that there will be the same pressure on the outside and inside of the liner. The aluminum inside the liner is then machined away.
