Abstract

A coolant outlet system for a cylinder head associated with an engine includes a core hole communicating with an upper surface thereof, wherein the core hole is in fluid communication with a coolant jacket of the cylinder head. The coolant outlet system includes an outlet tube having a first end and a second end, wherein the first end of the outlet tube is coupled to the core hole. The coolant outlet system also includes a jumper elbow coupled to the second end of the outlet tube, wherein the outlet tube and the jumper elbow provide fluid communication between the coolant jacket and an engine crankcase to introduce coolant discharged from the core hole into the engine crankcase.

Claims

1. A coolant outlet system for a cylinder head associated with an engine, wherein the cylinder head includes a core hole communicating with an upper surface thereof, wherein the core hole is in fluid communication with a coolant jacket of the cylinder head, the coolant outlet system comprising:

an outlet tube having a first end and a second end, wherein the first end of the outlet tube is coupled to the core hole; and

a jumper elbow coupled to the second end of the outlet tube, wherein the outlet tube and the jumper elbow provide fluid communication between the coolant jacket and an engine crankcase to introduce coolant discharged from the core hole into the engine crankcase.

2. The coolant outlet system of claim 1, wherein the upper surface includes a recessed and non-peripheral surface of the cylinder head.

3. The coolant outlet system of claim 2 further comprising a sealing member to encapsulate the coolant being transferred between the recessed and non-peripheral surface and the jumper elbow.

4. The coolant outlet system of claim 1, wherein the outlet tube includes at least one of a ridged material, a flexible material, and a combination thereof.

5. The coolant outlet system of claim 1, wherein the jumper elbow is embodied as a unitary component coupled to a flange of the cylinder head.

6. The coolant outlet system of claim 1, wherein the jumper elbow includes a bracket and an elbow piece, wherein the bracket is coupled to a flange of the cylinder head and the elbow piece is coupled to the bracket.

7. The coolant outlet system of claim 1, wherein the cylinder head is associated with a locomotive engine.

8. The coolant outlet system of claim 1, wherein the jumper elbow is mechanically coupled to the cylinder head such that the jumper elbow acts as a locating device to orient a power assembly of the engine in the crankcase.

9. A cylinder head associated with an engine, wherein the cylinder head includes a core hole communicating with an upper surface thereof, the cylinder head comprising:

a coolant jacket formed within the cylinder head, wherein the core hole is in fluid communication with the coolant jacket; and

a coolant outlet system in fluid communication with the coolant jacket for discharging coolant from the core hole into an engine crankcase, the coolant outlet system comprising;

an outlet tube having a first end and a second end, wherein the first end of the outlet tube is coupled to the core hole; and

a jumper elbow coupled to the second end of the outlet tube, wherein the outlet tube and the jumper elbow provide fluid communication between the coolant jacket and the engine crankcase.

10. The cylinder head of claim 9, wherein the upper surface includes a recessed and non-peripheral surface of the cylinder head.

11. The cylinder head of claim 10 further comprising a sealing member to encapsulate the coolant being transferred between the recessed surface and the jumper elbow.

12. The cylinder head of claim 9, wherein the outlet tube includes at least one of a ridged material, a flexible material, and a combination thereof.

13. The cylinder head of claim 9, wherein the jumper elbow is embodied as a unitary component coupled to a flange of the cylinder head.

14. The cylinder head of claim 9, wherein the jumper elbow includes a bracket and an elbow piece, wherein the bracket is coupled to a flange of the cylinder head and the elbow piece is coupled to the bracket.

15. The cylinder head of claim 9, wherein the cylinder head is associated with a locomotive engine.

16. An engine comprising:

a cylinder head including a core hole communicating with a recessed surface thereof, the cylinder head further comprising;

a coolant jacket formed within the cylinder head, wherein the core hole is in fluid communication with the coolant jacket; and

a coolant outlet system in fluid communication with the coolant jacket for allowing an outflow of coolant from the core hole, the coolant outlet system comprising;

an outlet tube having a first end and a second end, wherein the first end of the outlet tube is coupled to the core hole; and

a jumper elbow coupled to the second end of the outlet tube; and

a crankcase in fluid communication with the coolant jacket via the outlet tube and the jumper elbow, wherein the crankcase is adapted to receive the coolant discharged from the core hole of the cylinder head via the outlet tube and the jumper elbow.

17. The engine of claim 16 further comprising a sealing member to encapsulate the coolant being transferred between the recessed surface and the jumper elbow.

18. The engine of claim 16, wherein the outlet tube includes at least one of a ridged material, a flexible material, and a combination thereof.

19. The engine of claim 16, wherein the jumper elbow is embodied as a unitary component coupled to a flange of the cylinder head.

20. The engine of claim 16, wherein the jumper elbow includes a bracket and an elbow piece, and wherein the bracket is coupled to a flange of the cylinder head and the elbow piece is coupled to the bracket.
