[0045] Referring now to the drawings, particularly by their reference numbers, FIG. 1 illustrates a vehicle 100 depicted in a side perspective view, in accordance with an embodiment of the present claimed subject matter. The vehicle 100 includes a chassis 102, a frame 104, and an air filter assembly 106. As shown, the chassis 102 and the frame 104 are attached together.

[0046] FIG. 1A illustrates an isometric view of an air conduit 101 in an air intake system 100″ in accordance with an embodiment of the present invention. A person skilled in the art may understand the air intake system 100″ as an assembly of a snorkel, pre-cleaner, a cleaner and the air conduit 101. Further, a combination of the pre-cleaner and the cleaner would be referred to as air filter 108 for purpose of the present claimed subject matter.

[0047] In another embodiment, the air conduit 101 may include an inlet end 103 and an outlet end 105. The inlet end 103 may be coupled to the air filter 108 of the air intake system 100″. Further, the outlet end 105 may be opposite to the inlet end 103, such that the filtered air from the air filter 108 enters the air conduit 101 via the inlet end 103 and exits via the outlet end 105. Additionally, the outlet end 105 may be coupled to a turbocharger. In an embodiment of the present invention, the air conduit 101 may extend horizontally between the inlet end 103 and the outlet end 105.

[0048] In another embodiment, the inlet end 103 may be coupled to the air filter 108 via a straight hose. Further, the outlet end 105 may be coupled to the turbocharger via a hose reducer. In an embodiment of the present invention, the air conduit 101 may be mounted on a chassis of a vehicle by way of one or more brackets and one or more dampers. The bracket is fastened by screw with the chassis. Additionally, a damper may be fastened between the bracket and the chassis. The damper provides a cushioning effect and reduces the vibration of the air conduit 101. The bracket and damper together constitute a mounting assembly. In an embodiment of the present invention, without any limitation the damper may be made of a rubber material and a plastic material. Further, the air conduit 101 may be made of a plastic material, an aluminum material and a steel material.

[0049] In another embodiment, the air conduit 101 may be cylindrical in shape. In another embodiment of the present invention, the air conduit 101 may be in shape of a polygon, such as a square or a rectangle.

[0050] In another embodiment, the air conduit 101 may include a plurality of segments. In an exemplary embodiment, the air conduit 101 may be a single structure with a plurality of demarcations, each demarcation of the plurality of demarcations corresponds to at least one segment of the plurality of segments. Accordingly, it may be apparent to a person skilled in the art that the air conduit 101 may be molded and manufactured as a single structure, without requirement of any intermediate connectors for intra-conduit coupling. Thus, physically the air conduit 101 may be understood as a single structure without any physically separate connectors or segments. But, for the sake of reference and understanding, the air conduit 101 may have the plurality of demarcations, such that the plurality of demarcations may represent various sections or portions of the single structured air conduit 101. In an example, the demarcations may be represented by actual markings on the air conduit 101. In another example, the demarcations may be represented by imaginary or notional markings on the air conduit 101. Further, each demarcation of the plurality of demarcations may correspond to at least one segment of the plurality of segments. Since, the air conduit 101 may be a single structure, the plurality of segments may be understood as notional segments, such that physically the plurality of segments are not separate structures but representative of various sections or portions of single structured air conduit 101. Thus, in a scenario when the air conduit 101 is a single structure, the at least one segment of the plurality of segments may be understood as a notional segment.

[0051] In another embodiment, the air conduit 101 comprises a plurality of physical segments detachably coupled to each other. Accordingly, it may be apparent to a person skilled in the art that the air conduit 101 may be formed by multiple structures connected to each other by intermediate connectors for intra-conduit coupling. Thus, operationally the air conduit 101 may be understood as a single structure but with physically separate connectors and segments. Thus, in a scenario when the air conduit 101 is not a single structure physically, the at least one segment of the plurality of segments may be understood as a physical segment separate from other segments.

[0052] In another embodiment, a first segment of the plurality of segments bends at one or more predefined angles to couple to a second segment of the plurality of segments. Here, the segments may be one of notional and physical segment. In an embodiment of the present invention, the one or more predefined angles are in a range from 20 degrees to 120 degrees. Further, the one or more predefined angles facilitate flow of air in the air conduit 101 at a predefined pressure within a range from 8 inches of water column to 20 inches of water column. Also, the first segment of plurality of segments is coupled to the second segment of plurality of segments by one of: a hump hose and a straight hose, when the segments are physical segments.

[0053] In another embodiment, one of: the first segment and the second segment of the plurality of segments has a length in a range from 300 mm to 1000 mm. Further, one of: the first segment and the second segment of the plurality of segments has a diameter in a range from 100 mm to 200 mm.

[0054] In another embodiment, at least one segment of the plurality of segments is in one of: “Z” shape, “L” shape, “S” shape, and skewed “S” shape. Further, at least one segment of the plurality of segments extends along one of: X axis, Y axis, and Z axis of the air conduit 101. Here, the segments may be one of notional and physical segment. Also, at least one segment of the plurality of segments has one or more sensors and one or more compressor ports mounted thereon. The one or more sensors include at least one of: a mass flow sensor, a pressure sensor and a temperature sensor.

[0055] Thus, the present invention discloses a structure of the air conduit 101, placed below the cabin that maintains the air pressure in the air conduit 101, while safely housing the air conduit 101 in confined space. Specifically, the length, diameter and angle of bending of various segments of the air conduit 101 contribute to a low resistance passage for the filtered air, amounting to maintenance of air pressure. Additionally, the structure disclosed by the present invention is formed to accommodate in confined space between the air filter 108 and the turbocharger, below the cabin of the vehicle. Therefore, the air conduit 101 disclosed in the present invention provides a two-fold advantage of maintaining an optimum pressure of the filtered air and accommodating the air conduit 101 in a confined space.
