Abstract

Implementations described herein relate to features for a single module aftertreatment system. The single module aftertreatment system includes a casing, a catalyst within the casing, and a sensor mount coupled to the casing. The sensor mount is angled relative to a portion of the casing at a position where the sensor mount is coupled to the casing. The sensor mount includes a first attachment leg, a second attachment leg, and an angled mounting portion. The angled mounting portion connects the first attachment leg to the second attachment leg. The sensor mount is coupled to the casing by the first attachment leg and the second attachment leg such that the first attachment leg, the second attachment leg, and the angled mounting portion form an air gap relative to the casing.

First claim

What is claimed is:

1. A single module aftertreatment system comprising:
a casing;
a catalyst within the casing; and
a sensor mount coupled to the casing,
wherein the sensor mount comprises a first attachment leg, a second attachment leg, and an angled mounting portion, the angled mounting portion connecting the first attachment leg to the second attachment leg; and
wherein the sensor mount is coupled to the casing by the first attachment leg and the second attachment leg, and wherein the first attachment leg, the second attachment leg, and the angled mounting portion form an air gap relative to the casing.

2. The single module aftertreatment system of claim 1 , wherein the first attachment leg includes a first vertical portion and a first attachment portion, wherein the second attachment leg includes a second vertical portion and a second attachment portion, and wherein the second vertical portion of the second attachment leg is shorter than the first vertical portion of the first attachment leg.

3. The single module aftertreatment system of claim 2 , wherein the first attachment portion includes a first extension and a second extension, the first extension and the second extension coupling the sensor mount to the casing and reducing conductive heat transfer from the casing to the sensor mount.

4. The single module aftertreatment system of claim 3 , wherein the first extension and the second extension are curved so as to conform to a curvature of the casing.

5. The single module aftertreatment system of claim 4 further comprising insulation positioned within at least a portion of the air gap formed by the first attachment leg, the second attachment leg, and the angled mounting portion.

6. A sensor mount for mounting components of an aftertreatment system, the sensor mount comprising:
a first attachment leg comprising a first vertical portion and a first attachment portion;
a second attachment leg;
an angled mounting portion connecting the first attachment leg to the second attachment leg,
wherein the first attachment portion of the first attachment leg comprises a first extension and a second extension;
wherein the sensor mount is coupled to a casing of the aftertreatment system by the first extension, the second extension, and the second attachment leg;
wherein the first extension and the second extension reduce conductive heat transfer from the casing to the sensor mount; and
wherein the first attachment leg, the second attachment leg, and the angled mounting portion form an air gap relative to the casing.

7. The sensor mount of claim 6 , wherein the second attachment leg comprises a second vertical portion and a second attachment portion, and wherein the second attachment portion comprises a first extension and a second extension.

8. The sensor mount of claim 7 , wherein the second vertical portion is shorter than the first vertical portion.

9. The sensor mount of claim 6 , wherein insulation is positioned within the air gap.

10. The sensor mount of claim 6 , wherein the first extension and the second extension are curved to conform to a curvature of the casing.

11. A sensor mount for mounting components of an aftertreatment system, the sensor mount comprising,
a first attachment leg comprising a first vertical portion and a first attachment portion extending from the first vertical portion; and
a second attachment leg comprising a second vertical portion and a second attachment portion extending from the second vertical portion,
wherein each of the first attachment portion and the second attachment portion comprises a first extension and a second extension, and
wherein the first extension and the second extension are curved to conform to a curvature of a casing of the aftertreatment system for mounting the sensor mount to the casing.

12. The sensor mount of claim 11 , further comprising a mounting portion that connects the first attachment leg to the second attachment leg.

13. The sensor mount of claim 12 , wherein the first attachment leg, the second attachment leg, and the mounting portion define an air gap, and wherein insulation is positioned within the air gap.

14. The sensor mount of claim 12 , wherein the mounting portion is angled relative to the casing, the first attachment leg, and the second attachment leg.

15. The sensor mount of claim 11 , wherein each of the first vertical portion and the second vertical portion extends radially from a surface of the casing, and wherein the first attachment portion and the second attachment portion extend at an angle from the first vertical portion and the second vertical portion, respectively.

16. The sensor mount of claim 11 , wherein the second vertical portion is shorter than the first vertical portion.
