Abstract

A system and attendant assembly for incorporating at least one alternate fuel supply, such as of the type used in combination with a conventional distillate fuel, to power a heavy duty industrial vehicle, such as a mine haul dump truck. The system and attendant assembly includes a mounting assembly structured for containment and support of a primary fuel tank and an auxiliary fuel tank. The mounting assembly is disposed on a mounting area laterally adjacent between the two tires on a side of the truck, wherein the mounting assembly and mounting area are cooperatively disposed and structured to facilitate storage of the alternate fuel and operative communication and distribution thereof with the powering operations of the vehicle.

Claims

1. A hybrid fuel assembly for modifying an industrial vehicle to include at least one alternate fuel supply, said assembly comprising:

a mounting area disposed on the industrial vehicle, said mounting area sufficiently dimensioned and structured to operatively retain a mounting assembly,

said mounting assembly cooperatively structured to operatively engage said mounting area, wherein said mounting assembly comprises;

a primary fuel tank formed along a hollow interior within said mounting assembly for holding hydraulic fluid,

an auxiliary fuel area sufficiently dimensioned and structured to operatively retain an auxiliary fuel tank for holding liquefied nitrogen gas,

said auxiliary fuel tank cooperatively structured to operatively engage said auxiliary fuel area,

a shield assembly structured to enclose and secure the auxiliary fuel tank within said auxiliary fuel area on said mounting assembly,

said mounting assembly further structured and disposed to facilitate operative communication of said primary fuel tank with a hydraulic lift bed of the vehicle, and

said mounting assembly further structured and disposed to facilitate operative communication of said auxiliary fuel tank with a powering engine of the vehicle.

2. The assembly as recited in claim 1 further comprising a vaporizer structured and configured to convert the liquefied natural gas into a gaseous state for use by a powering engine of the vehicle.

3. The assembly as recited in claim 2 wherein said vaporizer is mounted in an area substantially beneath said mounting assembly.

4. The assembly as recited in claim 2 wherein said mounting assembly further comprises a vaporizer access sufficiently dimensioned to facilitate the maintenance of said vaporizer by an operator.

5. The assembly as recited in claim 4 wherein said vaporizer access comprises an opening substantially beneath said mounting assembly.

6. The assembly as recited in claim 1 wherein said auxiliary fuel area further comprises an auxiliary fuel platform formed along a lower interior of said mounting assembly.

7. The assembly as recited in claim 6 wherein said vaporizer is disposed in underlying relation to said auxiliary fuel platform.

8. The assembly as recited in claim 1 wherein said auxiliary fuel area comprises at least one auxiliary fuel retainer formed along a rear interior of said mounting assembly, said auxiliary fuel retainer shaped to conform to an exterior of said auxiliary fuel tank.

9. The assembly as recited in claim 8 wherein said auxiliary fuel retainer comprises a partially arching structure formed to engage said auxiliary fuel tank in abutting and partially surrounding relations, when said auxiliary fuel tank is disposed in an operative engagement with said auxiliary fuel area.

10. The assembly as recited in claim 1 wherein said mounting assembly comprises at least one hydraulic refill port in fluid communication with said primary fuel tank.

11. The assembly as recited in claim 1 wherein said mounting assembly further comprises a diesel access port in fluid communication with a fluid interconnect.

12. The assembly as recited in claim 11 wherein said fluid interconnect is in fluid communication with said diesel access port and a second hybrid fuel assembly.

13. The assembly as recited in claim 1 wherein said mounting assembly further comprises a liquefied nitrogen gas access port in fluid communication with said auxiliary fuel tank.

14. The assembly as recited in claim 1 wherein said primary fuel tank comprises at least one baffle formed along an interior of said primary fuel tank, said at least one baffle structured and disposed to partition said primary fuel tank into a plurality of primary fuel compartments.

15. The assembly as recited in claim 14 wherein said plurality of primary fuel compartments are sufficiently shaped and dimensioned to reduce the slosh dynamics of said primary fuel compartment.

16. The assembly as recited in claim 14 wherein said primary fuel tank comprises a first baffle in juxtaposing disposition and perpendicularly disposed relative to a second baffle.

17. The assembly as recited in claim 1 wherein said mounting assembly further comprises a plurality of shock absorber bushings.

18. The assembly as recited in claim 1 wherein said mounting assembly further comprises at least one mounting structure.

19. The assembly as recited in claim 1 wherein said mounting assembly further comprises an access ladder disposed on a side of said mounting assembly, and sufficiently dimensioned as to allow an operator to gain access to a bed hoist cylinder of the vehicle.

20. The assembly as recited in claim 1 wherein said auxiliary fuel tank comprises between approximately 250 to 350 gallons of liquefied natural gas.

21. The assembly as recited in claim 1 wherein said primary fuel tank comprises between approximately 200 to 300 gallons of hydraulic fluid.

22. The assembly as recited in claim 1 wherein the mounting area is disposed laterally adjacent between two tires on a side of the vehicle.

23. The assembly as recited in claim 1 wherein said auxiliary fuel tank comprises a liquid volume greater than a liquid volume of said primary fuel tank.

24. The assembly as recited in claim 1 wherein the vehicle is a heavy duty industrial vehicle.

25. The assembly as recited in claim 1 wherein the vehicle comprises a mine haul dump truck.
