Abstract

A diesel exhaust fluid (DEF) tank for an off-road vehicle including a first conduit channel molded into an exterior surface of the DEF tank, at a first depth, in which the first conduit channel is configured to guide a first conduit along the exterior surface of the DEF tank. The DEF tank further including a second conduit channel molded into the exterior surface of the DEF tank at a second depth, different than the first depth, in which the second conduit channel is configured to guide a second conduit, and the first depth and the second depth are selected to create a vertical gap between the first conduit and the second conduit at an intersection of the conduits.

First claim

The invention claimed is:

1. A diesel exhaust fluid (DEF) tank configured to be used in an off-road vehicle, comprising:
a first conduit channel molded into an exterior surface of the DEF tank at a first depth, wherein the first conduit channel is configured to guide a first conduit along the exterior surface of the DEF tank; and
a second conduit channel molded into the exterior surface of the DEF tank at a second depth, wherein the second conduit channel intersects the first conduit channel, the second depth is different than the first depth, the second conduit channel is configured to guide a second conduit along the exterior surface of the DEF tank, and the first depth and the second depth are selected to create a first gap between the first conduit and the second conduit at a point where the first conduit and the second conduit would otherwise intersect.

2. The DEF tank of claim 1 , wherein the first conduit comprises a DEF bundle configured to fluidly connect the DEF tank and a supply module, wherein the supply module is configured to be coupled to the exterior surface of the DEF tank.

3. The DEF tank of claim 1 , wherein the second conduit comprises an electrical conduit configured to be electrically connected to an electrical device, wherein the electrical device is configured to be coupled to the exterior surface of the DEF tank.

4. The DEF tank of claim 1 , comprising a metal insert molded into the DEF tank, wherein the metal insert is configured to facilitate coupling an auxiliary component to the DEF tank.

5. The DEF tank of claim 4 , comprising a recess molded into the exterior surface of the DEF tank, wherein:
the recess is configured to accept a clamp, wherein the clamp is configured to secure the first conduit within the first conduit channel; and
the metal insert is threaded and configured to interface with a bolt, wherein the bolt is configured to secure the clamp to the exterior surface of the DEF tank within the recess.

6. The DEF tank of claim 1 , wherein the first conduit channel is sloped.

7. The DEF tank of claim 6 , wherein the first conduit channel is configured to direct the first conduit along a curved path along the exterior surface of the DEF tank.

8. The DEF tank of claim 1 , wherein the first depth is selected to create a second gap between the first conduit and an access door positioned adjacent to the DEF tank, wherein the first conduit comprises a DEF bundle.

9. The DEF tank of claim 8 , comprising an electrical distribution center recess molded into the exterior surface of the DEF tank at a third depth, wherein the electrical distribution center recess is configured to receive an electrical distribution center, and the third depth is selected to create a third gap between the electrical distribution center and the access door.

10. A diesel exhaust fluid (DEF) tank configured to be used in an off-road vehicle, comprising:
a drain channel molded into an exterior surface of the DEF tank comprising an inlet and an outlet, wherein the drain channel is configured to:
provide structural support to the DEF tank; and
guide fluid present on the exterior surface of the DEF tank downwardly through the drain channel along the exterior surface of the DEF tank and through the outlet to a region below the DEF tank; and

a sloped wall molded into the exterior surface of the DEF tank above the drain channel, wherein the sloped wall is configured to funnel the fluid present on the exterior surface of the DEF tank downwardly into the inlet of the drain channel.

11. The DEF tank of claim 10 , comprising a DEF supply module recess molded into the exterior surface of the DEF tank, wherein:
the DEF supply module recess is configured to receive a DEF supply module; and
the sloped wall is configured to funnel the fluid from the DEF supply module recess into the drain channel.

12. The DEF tank of claim 11 , wherein the DEF supply module recess comprises an isolation mount recess configured to accept an isolation mount of the DEF supply module.

13. The DEF tank of claim 10 , comprising a metal insert molded into the DEF tank.

14. The DEF tank of claim 13 , wherein the metal insert comprises a fill neck configured to enable the DEF tank to be filled with DEF, and the sloped wall is configured to funnel the fluid from a portion of the exterior surface of the DEF tank surrounding the fill neck into the drain channel.

15. The DEF tank of claim 10 , wherein the drain channel is formed vertically along a side exterior surface of the DEF tank.
