Abstract
An air intake system for an off-road vehicle includes an intake conduit upstream of a segmented debris removal device and a mail filter element. A baffle is disposed in the intake conduit and extends into the incoming air stream to avoid swirl in the air stream and provide more even air flow distribution into the segments of the segmented debris removal device. The baffle may have two generally parallel elements spaced from one another to reduce mixing of air regions separated by the baffle. The baffle reduces or eliminates vortices that adversely affect air flow into the segmented debris removal device.
Claims14
An air intake system for off-road vehicles, comprising:
- a filter element;
- a segmented debris removal assembly upstream of the filter element;
- a conduit upstream of the segmented debris removal assembly;
- and
- a baffle disposed in the conduit and configured to reduce swirl of an incoming air stream to substantially uniformly introduce the air stream into segments of the segmented debris removal assembly, the baffle including first and second generally parallel baffle elements extending into the incoming air stream, the first baffle element positioned to extend farther into the incoming air stream than the second baffle element.
An air intake system for off-road vehicles, comprising:
- a filter element;
- a segmented debris removal assembly upstream of the filter element;
- a conduit upstream of the segmented debris removal assembly;
- and
- a baffle disposed in the conduit and configured to reduce swirl of an incoming air stream to substantially uniformly introduce the air stream into segments of the segmented debris removal assembly, wherein the baffle comprises first and second generally parallel baffle elements extending into the incoming air stream, wherein the first and second baffle elements are joined to one another by a web, and wherein the first and second baffle elements and the web comprise a single piece of bent metal.
An air intake system for off-road vehicles, comprising:
- a filter element;
- a segmented debris removal assembly upstream of the filter element;
- a conduit upstream of the segmented debris removal assembly;
- and
- a baffle disposed in the conduit and having first and second baffle elements spaced from one another and extending in a direction generally transverse to a direction of an incoming air stream to reduce swirl of an incoming air stream to substantially uniformly introduce the air stream into segments of the segmented debris removal assembly, the first baffle element positioned to extend farther into the incoming air stream than the second baffle element.
An air intake system for off-road vehicles, comprising:
- a filter element;
- a segmented debris removal assembly upstream of the filter element;
- a conduit upstream of the segmented debris removal assembly;
- and
- a baffle disposed in the conduit and having first and second baffle elements spaced from one another and extending in a direction generally transverse to a direction of an incoming air stream to reduce swirl of an incoming air stream to substantially uniformly introduce the air stream into segments of the segmented debris removal assembly, wherein the first and second baffle elements are joined to one another by a web, and wherein the first and second baffle elements and the web comprise a single piece of bent metal.
An air intake system for off-road vehicles, comprising:
- a baffle configured to be disposed in a vehicle air intake conduit and having first and second baffle elements of different lengths, spaced from one another and extending in a direction generally transverse to a direction of an incoming air stream to reduce swirl of an incoming air stream to substantially uniformly introduce the air stream into segments of a segmented debris removal assembly, wherein the first baffle element is disposed to be upstream of the second baffle element when the baffle is placed in the vehicle air intake, and wherein the first baffle element extends farther into the incoming air stream than the second baffle element.
