<p>The invention relates to a method of die casting a cylinder block of aluminum where cylinder liners of another material are cast-in. A cylindrical insert (14) is placed in the liner, leaving a gap (a) between the outer surface of the insert 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 (15), so that there will be the same pressure on the outside and inside of the liner.</p> |
