The present invention relates to a hood (40) of a multi cyclone block (12) and an air cleaner (10). The cyclone block (12) has a plurality of cyclone cells (28). The hood (40) having at least one hood-inlet (50) and at least one hood-outlet (52) for air to be fed to the cyclone cells (28). The at least one hood-outlet (52) is designed for surrounding, a plurality of cell-inlets (36) of the cyclone cells (28) of the cyclone block (12). A wall (70) of the hood (40) defines a distributor volume (72) inside the hood (40), which is located between the at least one hood-inlet (50) and the at least one hood-outlet (52). The wall (70) has at least one line or area of inflection (74), where at least one inner surface of the wall (70) changes its curvature.

A vehicle component including a component body defining an aperture and including an outer textured surface surrounding the aperture on an exterior side of the component body; and a mesh extending over the aperture, a portion of the mesh being molded into at least a portion of the component surrounding the aperture, a surface of the portion of the mesh abutting the outer textured surface surrounding the aperture. A method includes disposing a mesh in a mold shaped for forming the plastic item, a portion of the mesh being disposed on portions of the mold having a textured surface surrounding at least a part of an aperture defining portion, the mesh being disposed in the mold over the aperture defining portion; and filling the mold with plastic, the mesh being molded in a textured surface of the plastic item formed by the textured surface of the mold.

An air cleaner has a body, an intake part to take air into the body, an exhaust pipe to exhaust the air from the body, a mounting section to mount an air flow meter to the exhaust pipe, a rib disposed on an inner surface of the body, and a straightening element disposed on an inner surface of the exhaust pipe. The rib extends toward the exhaust pipe and the straightening element extends in a same direction where the rib extends. The straightening element is located closer to the body than the mounting section.

An intake device includes an air filter that filters intake air for an internal combustion engine, a filter casing housing the air filter, and an air physical quantity sensor. The filter casing includes an intake passage to allow the intake air to pass from upstream to downstream of the air filter. The filter casing has a passage wall portion that is electrically conductive and exposed to the intake passage on a downstream side of the air filter. The air physical quantity sensor has: a sensor element that detects a specific physical quantity related to the intake air on a downstream side of the air filter; and a grounding structure electrically connected to the passage wall portion for grounding the sensor element.

Various embodiments relate to a filter housing seal member. The filter housing seal member includes a first member end and a second member end disposed axially away from the first member end. A first member portion is disposed between the first member end and the second member end. A second member portion is disposed between the first member end and the second member end. The second member portion is disposed radially away from the first member portion. An undercut is positioned along the first member portion, the undercut configured to receive and form a seal with a filter seal member of a filter element.

Methods and systems are provided for an airbox. In one example, the airbox is a single piece comprising features to receive and retain a platform for an air filter. The airbox comprises curved elastomers which engage with coupling elements of the platform.

A filter element includes first filter media, second filter media, a frame, and a seal member. The frame is coupled to the first filter media and the second filter media, the frame securing the first filter media and the second filter media into a V-shape. The seal member is attached to and extends from the frame. The seal member includes a U-shaped channel structured to receive a ridge of a housing when the filter element is installed in the housing. The seal member is structured to form a seal between the filter element and the housing when the filter element is installed in the housing.

An air cleaner includes a housing having an air inlet and an air outlet. The air cleaner further includes a filter media coupled to the housing and positioned between the air inlet and the air outlet, the filter media configured to filter an air flow that enters the housing through the air inlet and exits the housing through the air outlet. The air cleaner includes a rectifier coupled to the housing and positioned at a location downstream of the filter media, the rectifier including an outer ring that is orthogonally oriented with respect to the air flow.

The present invention relates to a hood (40) of a multi cyclone block (12) and an air cleaner (10). The cyclone block (12) has a plurality of cyclone cells (28). The hood (40) having at least one hood-inlet (50) and at least one hood-outlet (52) for air to be fed to the cyclone cells (28). The at least one hood-outlet (52) is designed for surrounding, a plurality of cell-inlets (36) of the cyclone cells (28) of the cyclone block (12). A wall (70) of the hood (40) defines a distributor volume (72) inside the hood (40), which is located between the at least one hood-inlet (50) and the at least one hood-outlet (52). The wall (70) has at least one line or area of inflection (74), where at least one inner surface of the wall (70) changes its curvature.

Disclosed herein are air intake assemblies for internal combustion engines. In some embodiments, an air intake assembly includes an air filter configured to produce filtered air, a sealed filter housing configured to house the air filter therein, and an intake tube configured to convey the filtered air to an internal combustion engine. The filter housing includes an air intake port configured to provide intake air to the air filter.
