Abstract
The invention is directed to an arrangement for sealing a clearance between a cylinder head and a cylinder block of an engine with a metal gasket clamped therebetween. The metal gasket is formed of a metallic base plate which has a plurarity of openings and beads formed therearound. The base plate may include annular shims welded on the base plate around the openings and a resilient sealing member deposited on the base plate surrounding the openings. The gasket may be disposed in such a manner as to place tip ends of the beads toward the cylinder block which causes a smaller displacement relative to the beads in comparison with the cylinder head. The resilient sealing member may be arranged to have a section of different dimension between a portion located at a side facing the beads and other portion at the opposite side thereof, or between a portion located at a junction where two of the beads meet and other portion.
