CYLINDER HEAD GASKET FOR HIGH LOAD AND MOTION APPLICATIONS

摘要

A cylinder head gasket including at least three functional layers and at least two stoppers is provided. The first functional layer includes a first full bead extending around a combustion chamber opening and axially aligned with a second full bead of the second functional layer. The first stopper extends along the first functional layer between the combustion chamber opening and the first full bead for preventing over-compression of the first full bead. The second stopper is located beneath the second full bead of the second functional layer for increasing load on the second full bead, reducing head lift, and promoting an even distribution of the load. The second stopper is not attached to the second functional layer along and adjacent the second full bead, and thus an air gap is present between the second stopper and the second full bead when the gasket is not compressed.
