Cylinder head gasket assembly
A cylinder head gasket assembly includes a gasket and a wire. The gasket has a first side, a second side, and a cylinder bore opening extending through the first side and the second side. The gasket has a wall on the first side. The wall extends axially along the cylinder bore opening. The gasket has a ledge extending from the wall into the cylinder bore opening at the second side. The wire is ring-shaped. The wire is on the ledge and extends along the wall. Wax adheres the wire to the ledge.
1. A cylinder head gasket assembly comprising:
a gasket having a first side, a second side, and a cylinder bore opening extending through the first side and the second side;
the gasket having a wall on the first side, the wall extending axially along the cylinder bore opening;
the gasket having a ledge extending from the wall into the cylinder bore opening at the second side;
a wire that is ring-shaped, the wire being on the ledge and extending along the wall; and
wax adhering the wire to the ledge;
the cylinder bore opening has an axis;
the wall extends around the axis of the cylinder bore opening;
the gasket has an inner wall extending around the axis of the cylinder bore opening;
the ledge has a surface extending radially from the wall to the inner wall and terminating at the wall and the inner wall; and
the wire is on the surface and the wax adheres the wire to the surface.
2. The cylinder head gasket assembly of claim 1 , wherein the wax encases the wire.
3. The cylinder head gasket assembly of claim 1 , wherein the wall has a height axially along the cylinder bore opening and the wire has a height axially along the cylinder bore opening greater than the height of the wall.
4. The cylinder head gasket assembly of claim 1 , wherein the ledge has a groove receiving the wire.
5. The cylinder head gasket assembly of claim 1 , wherein:
the surface has a groove receiving the wire; and
the surface is planar from the groove to the wall and from the groove to the inner wall.
6. The cylinder head gasket assembly of claim 5 , wherein the inner wall is perpendicular to the surface.
7. The cylinder head gasket assembly of claim 5 , wherein the wall is perpendicular to the surface.
8. The cylinder head gasket assembly of claim 4 , wherein the wire has a round cross-section and the groove has a round cross-section sized to nest the wire.
9. The cylinder head gasket assembly of claim 1 , wherein the gasket has a first layer on the first side and a second layer on the second side, the first layer including the wall and the second layer including the ledge.
10. The cylinder head gasket assembly of claim 9 , wherein the first layer has a distal layer spaced from the second layer and a proximate layer between the second layer and the distal layer.
11. The cylinder head gasket assembly of claim 10 , wherein the proximate layer abuts the distal layer and the second layer.
12. The cylinder head gasket assembly of claim 9 , wherein the ledge has a groove receiving the wire and the wax.
13. The cylinder head gasket assembly of claim 9 , wherein the first layer and the second layer are metal.
14. The cylinder head gasket assembly of claim 1 , wherein the cylinder bore opening is perpendicular to the ledge at the ledge.
15. The cylinder head gasket assembly of claim 14 , wherein the first side and the second side are planar.
16. The cylinder head gasket assembly of claim 1 , wherein the wire is metal.
17. The cylinder head gasket assembly of claim 16 , wherein the gasket is metal.
18. The cylinder head gasket assembly of claim 1 , wherein the wall and the inner wall are concentric.
19. The cylinder head gasket assembly of claim 1 , wherein the wax is designed to dissolve at an engine-operating temperature.
20. The cylinder head gasket assembly of claim 1 , wherein the wall extends in one direction from the surface along the axis of the cylinder bore opening and the inner wall extends in an opposite direction from the surface along the axis of the cylinder bore opening.
