Abstract: A sealing system for an engine comprising a single layer of sheet material, the sheet having an upper surface adapted to sealably contact a first engine component and a lower surface adapted to sealably contact a second engine component, and bead portions profiled on the gasket, where the gasket profile is optimized with varying heights and widths so as to create portions of varying stiffness adjacent to one another. The bead portions are profiled so as to be concentric with a combustion or cylinder chamber of the engine, and the bead portions include a portion of high stiffness adjacent to a portion of high recovery, the portion of high stiffness having a sharper angle protruding away from the plane comprising the single layer gasket than for the adjacent portion of high recovery. The optimized profile allows use of single layer gaskets to replace multiple layer gaskets.
