Abstract

An off-road vehicle includes an air intake system that comprises an opening that, in operation, receives air, and an exhaust system that includes an exhaust stack positioned in the opening of the air intake system.

First claim

The invention claimed is:

1. An off-road vehicle comprising:
an air intake system comprising a housing having an opening that, in operation, receives air, wherein the housing is located outside an engine compartment of the off-road vehicle;
an exhaust system mounted on an inner surface of the housing of the air intake system, wherein the exhaust system comprises an exhaust stack that is positioned in the opening of the air intake system and transects a plane of the opening of the air intake system.

2. The off-road vehicle of claim 1 , wherein at least a portion of the inner surface of the housing is sloped, wherein the exhaust stack is mounted at least partially on the portion.

3. The off-road vehicle of claim 1 , wherein a fairing is coupled to the exhaust stack at a location where the exhaust stack is mounted on the inner surface of the housing.

4. The off-road vehicle of claim 1 , wherein the exhaust stack is located outside an engine compartment of the off-road vehicle.

5. The off-road vehicle of claim 1 , wherein the off-road vehicle is autonomous.

6. An off-road vehicle comprising:
an air intake system comprising:
an intake that, in operation, receives air via an intake flow path; and
a housing comprising an opening that receives the air via the intake flow path, wherein the housing is located outside an engine compartment of the off-road vehicle;

an exhaust system comprising an exhaust stack positioned in the opening of the housing, wherein the exhaust stack transects a plane of the opening of the housing.

7. The off-road vehicle of claim 6 , wherein the exhaust stack is mounted on an inner surface of the housing of the air intake system.

8. The off-road vehicle of claim 7 , wherein a fairing is coupled to the exhaust stack at a location where the exhaust stack is mounted on the inner surface of the housing.

9. The off-road vehicle of claim 6 , wherein the air intake system comprises a baffle to receive the air via the intake flow path.

10. The off-road vehicle of claim 9 , wherein the baffle is located laterally to an engine compartment of the off-road vehicle.

11. The off-road vehicle of claim 6 , wherein the air intake system comprises a screen positioned in the intake flow path.

12. The off-road vehicle of claim 11 , wherein the screen is positioned along the plane of the opening of the housing.

13. An air intake system comprising:
a housing comprising an opening, wherein the opening, in operation, receives air, wherein the housing is located outside an engine compartment of an off-road vehicle;
an exhaust stack mounted on an inner surface of the housing, wherein the exhaust stack extends through the opening of the housing and transects a plane of the opening of the housing.

14. The air intake system of claim 13 , wherein the air intake system comprises a screen mounted along the plane of the opening of the housing.

15. The air intake system of claim 14 , wherein the screen comprises an aperture that, in operation, enables the exhaust stack to extend through the aperture.

16. The air intake system of claim 13 , wherein the air intake system comprises a screen mounted within the housing.

17. The air intake system of claim 14 , wherein the screen is mounted on the inner surface of the housing.

18. The air intake system of claim 13 , wherein the air intake system comprises a fairing coupled to the exhaust stack at a location where the exhaust stack is mounted on the inner surface of the housing.
