Abstract

Official abstract text for this publication.

Methods and systems are provided for an air intake apparatus. In one example, a system comprises an air filter box rotatably mounted to an intake manifold. The air filter box rotates about an axis angled to a direction of forward vehicle travel.

First claim

Opening claim text (preview).

The invention claimed is: 1. A system, comprising: an air intake apparatus comprising an intake manifold and an air filter box, wherein the air filter box is mounted to the intake manifold via a rotatable bearing configured to rotate the air filter box about an axis of rotation angled to a forward direction of vehicle travel. 2. The system of claim 1 , wherein the intake manifold comprises a first rigid portion and a second deformable portion, wherein a rigidity of the first rigid portion is greater than a rigidity of the second deformable portion, and wherein the rotatable bearing is physically coupled to the first rigid portion of the intake manifold. 3. The system of claim 2 , wherein the air filter box comprises a first rigid portion and a second deformable portion, wherein the rigidity of the first rigid portion is greater than a rigidity of the second deformable portion, and wherein the rotatable bearing is physically coupled to the first rigid portion of the air filter box. 4. The system of claim 3 , wherein the second deformable portion of the intake manifold and the air filter box face a direction parallel to a direction of forward vehicle travel, and wherein the first rigid portion of the intake manifold and the air filter box face a direction opposite the direction of forward vehicle travel. 5. The system of claim 1 , wherein the axis of rotation is normal to the direction of forward vehicle travel. 6. The system of claim 1 , wherein the air filter box rotates in a first direction in response to a force exceeding a predetermined force, wherein the force and the first direction are opposite the direction of forward vehicle travel. 7. The system of claim 1 , wherein the rotatable bearing comprises a stop element configured to engage with a component to stop a rotation of the air filter box. 8. The system of claim 7 , wherein the component is an engine head. 9. An engine system, comprising: an engine; an intake manifold; and an air filter box rotatably coupled to the intake manifold via a rotatable bearing, wherein the rotatable bearing comprises a stop element configured to contact an engine head of the engine during a rotation of the air filter box. 10. The engine system of claim 9 , wherein the air filter box comprises a deformable portion and a rigid portion, wherein the deformable portion is configured to compress in response to a force greater than a threshold force, and wherein the force causes the air filter box to rotate. 11. The engine system of claim 9 , wherein the stop element contacts the engine head following a threshold rotation of the air filter box, wherein the threshold rotation is less than 90 degrees about an axis of rotation. 12. The engine system of claim 11 , wherein the axis of rotation is normal to a forward direction of vehicle travel, and wherein the threshold rotation is less than 45 degrees. 13. The engine system of claim 9 , wherein portions of the air filter box and the intake manifold facing a direction of forward vehicle travel are configured to deform in response to a force greater than a threshold force, and wherein portions of the air filter box and the intake manifold to which the rotatable bearing is coupled are configured not to deform in response to the force greater than the threshold force. 14. The engine system of claim 9 , wherein the rotatable bearing is a first rotatable bearing, and wherein an air duct is coupled to the air filter box via a second rotatable bearing. 15. The engine system of claim 14 , wherein a portion of the air duct proximal to the second rotatable bearing is configured to deform in response to a force greater than a threshold force, and wherein the first rotatable bearing is configured to rotate the air filter box about a first axis of rotation in a first direction, and wherein the second rotatable bearing is configured to rotate the air duct about a second axis of rotation in a second direction, opposite the first direction. 16. A system, comprising: an engine; an intake manifold; an air filter box rotatably coupled to the intake manifold via a first rotatable bearing, wherein the first rotatable bearing comprises a stop element configured to contact an engine head of the engine during a rotation of the air filter box; and an air duct rotatably coupled to the air filter box via a second rotatable bearing at a portion of the air filter box distal to the first rotatable bearing, wherein the first rotatable bearing is configured to rotate the air filter box in a first direction, and wherein the second rotatable bearing is configured to rotate the air duct in a second direction, opposite the first direction. 17. The system of claim 16 , wherein one or more of the air filter box and the air duct comprise a deformable section that comprises a lower structural rigidity that a remainder of the air filter box or the air duct. 18. The system of claim 16 , wherein the air duct is arranged in front of the air filter box relative to a direction of forward vehicle travel. 19. The system of claim 16 , wherein the air filter box and the air duct are configured to rotate in response to a force exceeding a threshold force, wherein the force is applied in a direction opposite a direction of forward vehicle travel.
