Abstract
The invention concerns a cylinder head gasket for sealing the region between cylinder head and a cylinder block having a cylinder liner of an internal combustion engine, comprised of at least one sealing sheet that has at least one combustion chamber passage opening and a combustion chamber crimp running around the combustion chamber passage opening, where a stop serving as a path limiter for the combustion chamber crimp is provided on the side of the combustion chamber crimp facing away from the combustion.chamber passage opening and which stop encloses the combustion chamber crimp laterally, where at least one sealing sheet has at least two concentric combustion chamber crimps, which are enclosed laterally by the stop.
Claims16
A cylinder head gasket for sealing a region between a cylinder head and a cylinder block of an internal combustion engine having a cylinder liner, comprising:
- at least one sealing sheet including at least on combustion chamber passage opening, and at least two combustion chamber crimps enclosing the passage opening;
- and
- a stop including a filled support crimp that includes a hardcoating material,
- wherein the at least two crimps are located between the passage opening and the stop, and
- wherein the stop encloses the at least two crimps.
A cylinder head gasket, comprising:
- at least two sealing sheets including at least one combustion chamber passage opening and at least two combustion chamber crimps enclosing the passage opening, and
- a spacer sheet located between the at least two sealing sheets, wherein the spacer sheet includes a filled support crimp which encloses the at least two combustion chamber crimps,
- wherein the at least two combustion chamber crimps are located between the passage opening and the filled support crimp and wherein the filled support crimp includes a hardcoating material.
A cylinder head gasket, comprising:
- at least two sealing sheets including at least one combustion chamber passage opening, at least two combustion chamber crimps enclosing the passage opening, and an edge crimp enclosing the at least two combustion chamber crimps, and
- a spacer sheet located between the at least two sealing sheets, wherein the spacer sheet includes a filled support crimp which is located between the at least two combustion chamber crimps and the edge crimp and wherein the filled support crimp includes a hardcoating material.
