Abstract:
A multi-layer cylinder head gasket providing improved sealing performance, stability, and a more rigid joint between two components is provided. The gasket includes a plurality of functional layers each including a full bead located between an inner edge and outer edge and surrounding a combustion chamber opening. A stopper is disposed between the functional layers and is located radially between the combustion chamber opening and the full bead. A coating material is applied to at least one surface of at least one functional layer and extends along a majority of the length of the functional layer. To achieve the improved performance, a region along the surface located between the inner edge and the full bead remains uncoated, or includes a reduced amount of the coating material. Alternatively, the stopper can be located between the combustion chamber opening and the inner edges of the functional layers to provide the uncoated region.
