ABSTRACT:
A multi-layered cylinder head gasket for positioning between a cylinder head and a cylinder block of an engine includes upper and lower compression layers and a stopper layer. The compression layers and stopper layer all include apertures that mate together to define a peripheral edge. The stopper layer further includes a folded portion and a main body portion. The folded portion has a plurality of waves that contact the main body portion of the stopper layer to form a stopper when folded over. The stopper is positioned at the peripheral edge of the mated aperture. The waves deform under high compression loads generated by the joining of the cylinder head and the cylinder block. The deformation balances the stresses generated by the compression loads around the mated aperture.
