Abstract

A vehicle including a powertrain assembly supported by the frame and an air intake assembly operably coupled to the powertrain assembly. The air intake assembly includes at least one inlet configured to direct air to different portions of an intake housing and filter positioned therein. The filter contains multiple sealing surfaces and a central air outlet.

First claim

What is claimed is:

1. A vehicle intake for a vehicle extending along a longitudinal centerline, comprising:
an air filter housing having a housing inlet and a housing portion;
a flat panel air filter having a filter inlet and a filter outlet; and
an airflow path through the filter inlet is substantially parallel to an airflow path through the filter outlet;
wherein the housing inlet is open to a direction of vehicle travel; and
a distance between the housing portion and the flat panel air filter at a forward portion of the air filter housing is greater than a distance between the housing portion and the filter at a rearwardmost portion of the air filter housing.

2. The vehicle intake of claim 1 , wherein an airflow path through the housing inlet is substantially perpendicular to the airflow path through the filter inlet.

3. The vehicle intake of claim 2 , wherein the airflow path through the housing inlet is substantially parallel to a direction of vehicle travel.

4. The vehicle intake of claim 1 , wherein the housing inlet is positioned at a first distance relative to the longitudinal centerline of the vehicle and the filter outlet is positioned at a second distance relative to the longitudinal centerline, and the first distance is less than the second distance.

5. The vehicle intake of claim 1 , wherein the housing includes a clean air volume downstream of the filter and configured to receive filtered air from the filter, and the filter is positioned laterally intermediate the housing inlet and the clean air volume.

6. The vehicle intake of claim 1 , wherein the housing includes a clean air volume downstream of the filter and configured to receive filtered air from the filter, and the filter is positioned laterally intermediate the longitudinal centerline and the clean air volume.

7. The vehicle intake of claim 1 , wherein the filter housing further contains a cover.

8. The vehicle intake of claim 1 , wherein the rearwardmost portion of the housing is positioned laterally outward of the forward portion of the housing.

9. The vehicle intake of claim 1 , wherein the housing portion contains a partition wall at the rearward portion of the housing partitioning a portion of the housing into an upper section and a lower section.

10. The vehicle intake of claim 7 , wherein the housing portion and the cover are removably coupled to each other, and removal of the cover exposes the filter.

11. The vehicle intake of claim 1 , wherein the air filter contains an arcuate lip at the filter outlet.

12. The vehicle intake of claim 11 , wherein the arcuate lip seals the filter at an interface of the housing.

13. The vehicle intake of claim 1 , wherein the housing inlet is defined by an arcuate surface.

14. The vehicle intake of claim 1 , wherein a projection of the filter on a vertical plane disposed longitudinally is greater than a projection of the filter on a vertical plane disposed laterally.

15. An air box configured to be fluidly coupled to an engine of a vehicle, the air box comprising:
a housing having a housing inlet; and
a filter positioned within the housing, the housing inlet contains a plurality of intake passages configured to direct air to different portions of the filter;
wherein the plurality of intake passages are forward facing when coupled to the vehicle.

16. The air box of claim 15 , wherein the housing inlet contains a plurality of walls defining the intake passages.

17. The air box of claim 16 , wherein the plurality of walls includes a first wall and a second wall and the second wall has a length greater than a length of the first wall.

18. The air box of claim 17 , wherein the first wall has a forwardmost extent positioned forward of that of the second wall.

19. The air box of claim 17 , wherein a first wall has a rearwardmost extent positioned forward of that of the second wall.

20. The air box of claim 19 , wherein the first wall is located a first distance relative to a vertical midpoint of the air box and the second wall is located a second distance relative to the vertical midpoint, and the first distance is less than the second distance.

21. The air box of claim 17 , wherein the filter is a flat panel filter.

22. The air box of claim 21 , wherein the first wall intersects the filter when viewed from a side perspective view.

23. The air box of claim 15 , wherein the housing contains a partition wall at a rear of the housing partitioning a portion of the housing into upper and lower sections.

24. An air box configured to be fluidly coupled to an engine of a vehicle, the air box comprising:
a housing; and
a filter positioned within the housing and having a filter media, a first portion defining an outer surface of the filter and a second portion defining an inner portion of the filter, and the filter media is positioned intermediate the first and second portions, and the second portion being positioned radially inward of the first portion, the second portion including an opening defining an outlet of the filter housing, the filter media is radially inward of the first portion;
wherein the first portion contains a first sealing surface and the second portion contains a second sealing surface and a third sealing surface.

25. The air box of claim 24 , wherein the opening is in fluid communication with the engine of the vehicle and configured to provide filtered air to the engine.

26. The air box of claim 24 , wherein the second portion is radially inward of the filter media.

27. The air box of claim 24 , wherein the filter includes an air opening configured to receive filtered away from the filter media, and the air opening is longitudinally offset from a true center of the filter.

28. The air box of claim 24 , wherein the second portion further contains a fourth sealing surface.

29. The air box of claim 24 , wherein the first sealing surface seals the filter against the housing and the second sealing surface seals the filter against an air valve of the engine.

30. The air box of claim 28 , wherein the third sealing surface seals the filter against a first portion of the housing and the fourth sealing surface seals the filter against a second portion of the housing.

31. An air box configured to be fluidly coupled to an engine of a vehicle, the air box comprising:
a flat-panel filter having a frame and a filter media positioned within the frame, and the frame includes an opening positioned radially inward of the frame and configured to provide filtered air to a throttle body of the engine;
wherein the filter frame contains an arcuate lip at the opening.

32. The air box of claim 31 , wherein an air path through the filter media is substantially parallel to an opening of the throttle body.

33. The air box of claim 31 , wherein the filter has a first dimension defining the filter height, a second dimension defining the filter width, and a third dimension defining the filter thickness, and the first and second dimension are larger than the third dimension.

34. The air box of claim 31 , wherein the opening is positioned radially inward of at least a portion of the filter media.

35. The vehicle intake of claim 1 , wherein an inner surface of the housing has tapered configuration extending from the forward
