Cylinder head cover with integral sleeve

1. A system, comprising: a cylinder head for a reciprocating engine; and a cylinder head cover configured to couple to the cylinder head, wherein the cylinder head cover comprises an ignition plug sleeve extension configured to house a portion of an ignition plug within the cylinder head cover, and the ignition plug sleeve extension is integral to the cylinder head cover, wherein the ignition plug sleeve extension comprises a first lower end and an ignition plug sleeve comprises a second upper end, and wherein the first lower end and the second upper end are vertically disposed directly opposite of each other and directly contact each other at a horizontal interface, and the first upper end and the second lower end is collinear.

2. The system of claim 1 , wherein the cylinder head cover and the ignition plug sleeve extension are cast.

3. The system of claim 1 , wherein the ignition plug sleeve extension defines an inner annular wall of the cylinder head cover.

4. The system of claim 3 , wherein the inner annular wall is centrally located within the cylinder head cover.

5. The system of claim 4 , wherein a portion of the inner annular wall extends into the cylinder head.

6. The system of claim 3 , wherein the inner annular wall defines a first bore portion having a first inner diameter and a second bore portion having a second inner diameter, and the first inner diameter is greater than the second inner diameter.

7. The system of claim 1 , wherein the cylinder head comprises the ignition plug sleeve, and the ignition plug sleeve extension and ignition plug sleeve directly contact each other.

8. The system of claim 7 , wherein the horizontal interface occurs outside the cylinder head cover.

9. The system of claim 7 , wherein the horizontal interface occurs inside the cylinder head cover.

10. The system of claim 1 , comprising the reciprocating engine having the cylinder head and the cylinder head cover.

11. A system, comprising: a cylinder head cover configured to couple to a cylinder head of a reciprocating engine, wherein the cylinder head cover comprises an ignition plug sleeve extension that forms an inner annular wall within the cylinder head cover that is configured to house a portion of an ignition plug within the cylinder head cover, and the ignition plug sleeve extension and the cylinder head cover comprise a single piece, wherein the ignition plug sleeve extension comprises a first lower end, an ignition plug sleeve comprises a second upper end, and wherein the first lower end and the second upper end are vertically disposed directly opposite of each other and directly contact each other at a horizontal interface, and the first lower end and second lower end is collinear.

12. The system of claim 11 , wherein the cylinder head cover and the ignition plug sleeve extension are cast.

13. The system of claim 11 , wherein the inner annular wall is centrally located within the cylinder head cover.

14. The system of claim 11 , wherein the cylinder head cover comprises an outer wall having a first length extending between a third end and a fourth end, the fourth end being configured to interface with the cylinder head, the ignition plug sleeve extension comprises a second length, and the first and second lengths are equal.

15. The system of claim 11 , wherein the cylinder head cover comprises an outer wall having a first length extending between a third end and a fourth end, the fourth end being configured to interface with the cylinder head, the ignition plug sleeve extension comprises a second length, and the second length is greater than the first length.

16. The system of claim 11 , wherein the inner annular wall forms an annular shoulder.

17. The system of claim 11 , wherein cylinder head cover and the ignition plug sleeve extension are made of an aluminum alloy.

18. A method, comprising; casting a cylinder head cover for coupling to a cylinder head, wherein the cylinder head cover comprises an ignition plug sleeve extension configured to house a portion of an ignition plug within the cylinder head cover, and the ignition plug sleeve extension is integral to the cylinder head cover; and coupling the cylinder head cover to the cylinder head to form a horizontal interface between a first lower end of the ignition plug sleeve extension and a second upper end of an ignition plug sleeve disposed within the cylinder head so that the first lower end is directly opposite from the second upper end in a vertical direction and the first lower end contacts the second upper end, the first upper end and the second lower end is collinear.

19. The method of claim 18 , disposing a portion of an ignition plug within the ignition plug sleeve extension.

20. The method of claim 18 , wherein the horizontal interface occurs outside the cylinder head cover.
