A gasket for preventing high-temperature fluid of an internal combustion engine from leaking is located between an adjacent pair of components of the engine. The gasket includes a gasket plate made of an electrically insulating material. The gasket plate has a hole. An annular sealing member is made of a material having a higher heat resistance than the gasket plate. The annular sealing member covers part of the gasket plate that defines the hole. Therefore, the gasket is capable of, for an extended period, preventing metal components in an internal combustion engine from directly contacting each other.

Method of manufacturing a gasket

A cylinder head gasket for sealing between a cylinder block and a cylinder head, composed of a composite base plate, the composite base plate comprising a core material plate and a compound layer formed on the front and back surfaces of the core material plate, the compound layer being formed by coating compound materials which contain a rubber and a fiber material. The cylinder head gasket is comprised of an annular groove which is formed by pressing the corresponding region around the cylinder bore of the compound layer, and a bead projecting from the surface of the compound layer which is formed by inserting the rubber material into the annular groove.

Cylinder head gasket

In order to prevent fuel leakage from a high pressure fuel pipe at a low temperature, a sealing capacity of a seal member provided in a fuel transfer portion of a high pressure fuel pipe is estimated in accordance with various conditions and the fuel pressure within the high pressure fuel pipe is controlled on the basis of the estimated sealing capacity so as to secure a sealing property in the fuel transfer portion.
