ABSTRACT:
A metal gasket of the invention is used for an internal combustion engine, especially for an engine with a cylinder liner. The gasket is formed of a first metal plate having a first hole greater than a hole of the engine, an annular ring and a sealing device. The annular ring has an inner size substantially corresponding to the hole of the engine, an outer size substantially corresponding to the first hole, and a thickness greater than that of the first metal plate. The annular ring is situated inside the first hole and attached to the first metal plate. The sealing device provides a surface pressure on the first plate outside the annular ring. Even if there is a gap between the upper end of the cylinder liner and an upper surface of the cylinder block, the annular ring can seal around the hole together with the sealing device.
