Abstract
A gasket assembly for an internal combustion engine having a cylinder head gasket and an exhaust manifold gasket. The cylinder head gasket and the exhaust manifold gasket have a common layer of gasket material. The gasket assembly is formed by stamping a cylinder head gasket portion for the engine in one region of a common layer of gasket material concurrently with stamping an exhaust gasket portion for the engine in an adjacent region of the common layer of material.
Description
- This is a divisional of application Ser. No. 11/677,090 filed Feb. 21, 2007.
- This invention relates generally to internal combustion engine exhaust manifold and cylinder head gaskets.
- As is known in the art, V-Engine, 14 and Diesel engines currently design unique gaskets for both the cylinder head and exhaust manifold. Both gaskets are separately manufactured, packaged, and shipped to engine assembly plants.
- In accordance with the present invention, a gasket assembly for an internal combustion engine is provided having a combined cylinder head gasket and an exhaust gasket. The cylinder head gasket and the exhaust gasket have a common layer of gasket material. The gasket assembly is formed by stamping a cylinder head gasket portion for the engine in one region of a common layer of gasket material concurrently with stamping an exhaust gasket portion for the engine in an adjacent region of the common layer of material.
- With such invention, an exhaust manifold gasket is formed as an integral appendage to a cylinder head gasket. The cylinder head gasket and the exhaust manifold gasket unit comprises a common layer of gasket base material, the cylinder head gasket having at least one additional layer of a different material bonded to the common gasket base material. The entire integrated gasket would be shipped as one piece to an engine plant and be installed prior to the cylinder head installation. At that point the exhaust manifold gasket would be a protruding appendage from the head deck joint. It could then: 1) be folded 90 degrees against the cylinder head exhaust face; or 2) be sheared from a perforation and installed against the cylinder head exhaust ports. Installation of the exhaust manifold would be conventional. The invention results in significant savings from supply base reduction, packaging, shipping, material handling.
- The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.
-
FIG. 1 is across section sketch of a portion of a V-6 or V-8 internal combustion engine having an integral cylinder head and exhaust manifold gasket according to the invention; -
FIG. 2 is an enlarged portion of the engine of FIG, 1, such enlarged portion being encircled by thecircle 2 inFIG. 2 ; -
FIG. 3 is a sketch of a common material used for both the cylinder head gasket and the exhaust manifold gasket ofFIG. 1 ; and -
FIG. 4 is an enlarged view of a portion ofFIG. 3 , such portion being enclosed by the circleFIG. 3 inFIG. 3 . - Like reference symbols in the various drawings indicate like elements.
- Referring now to
FIGS. 1 and 2 , a portion of aninternal combustion engine 10 is shown. Here theengine 10 is either a V-8 or V-6 engine having within anengine block 12 thereof a pair ofpistons 14 disposed within a pair ofcylinders 16 formed within theengine block 12. - A pair of
cylinder heads 20 is mounded to thecylinder block 12 over thecylinders 16. Ahead gasket 22, to be described in more detail below provides a seal between thecylinder block 12 and thecylinder head 20. - An exhaust manifold, 24 shown here for only one of the two
cylinders 16, it being understood that bothcylinders 16 would have such anexhaust manifold 24, is mounted to thecylinder head 20 with anexhaust gasket 28, to be described, being used to seal theexhaust manifold 24 and thecylinder head 20. - As shown more clearly in
FIG. 2 , thehead gasket 22 and theexhaust manifold gasket 28 are formed as anintegral unit 35. More particularly, a common gasket base material 30 (typically a 300 series hardened stainless steel) is used for both thecylinder head gasket 22 and theexhaust gasket 28. The cylinder head gasket 22 and theexhaust manifold gasket 28 thus have the common, single active base layer,gasket base material 30 with thecylinder head gasket 22 having at least one additional layer, here twolayers common material layer 30, bonded to the commongasket base material 30. It is noted that thecommon material layer 30 is a common sheet with the cylinder head gasket portion of thematerial 30 and the exhaust gasket portion of thematerial 30 being hinged together atregion 40. - Referring now also to
FIG. 3 , thecommon material 30 portion of theentire gasket unit 35 is formed in one stamping and then shipped as one piece to an engine plant for installation prior to cylinder head installation (assembly of the cylinder head to the engine block). At that point the exhaust manifold gasket is a protruding appendage from the head deck joint atregion 40. Thecommon material 30 could then: 1) be folded 90 degrees against the cylinder head exhaust face as shown inFIG. 1-4 , or 2) be sheared from a perforation alongregion 40 and installed against the cylinder head exhaust ports. Theadditional layers FIG. 2 ) are formed either as part of the base material forming operation or in separate dies (i.e., similar material, which can be mechanically staked, riveted, or spot-welded to the base layer in subsequent operations). - A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
