ABSTRACT:
The gasket of the invention is installed in an internal combustion engine having at least one cylinder bore and auxiliary combustion chamber. The gasket comprises first, second and third plates. The first plate includes a curved portion to define a hole for the cylinder bore and a flange extending away from the hole. The second plate is situated under the first plate, and the third plate is located under the second plate. The gasket further includes at least one main sealing device situated adjacent the curved portion, and an auxiliary bead formed on one of the first, second and third plates. The auxiliary bead surrounds the main bead and a portion corresponding to the mouth plate so that gas does not leak outside the auxiliary bead.
