Title: FLAT GASKET AND INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to a flat gasket (1) and to an internal combustion engine. Such flat gaskets (1) are particularly used in the hot gas region of an internal combustion engine. This flat gasket (1) is characterised in that the layered edge (4) of a first metal layer (10), surrounding the through-openings (2a, 2b), is embodied as a half-bead (II) surrounding the length of the layered edge (14) and facing away from a second layer (20), and in that the layered edge (24a, 24b) of the second metal layer (20), surrounding said through-openings (2a, 2b), is embodied as a full bead (21) surrounding the length of said layered edge (24a, 24b), facing away from the first layer (10) and consisting of two half-beads (27, 27'), and the layered edge (24a, 24b) of the second metal layer (20), surrounding said through-openings (2a, 2b), projects past the adjacently extending layered edge (14) of the first metal layer (10), at least in some areas, with the flank of the half-bead (27a, 27b) thereof which is adjacent to the through-opening (2a, 2b).
