20230003181 · 2023-01-05 ·

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.

Air flow conditioning device

A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

System and method for improving mass air flow signal quality

A filter assembly includes a conditioning device that conditions a flow of air upstream of a mass air flow sensor. The filter assembly includes a support frame. The filter assembly further includes a filter media coupled to the support frame, the filter media having a dirty side configured to receive a stream of air and a clean side configured to output a stream of air that has been filtered through the filter media. The filter assembly includes a conditioning device coupled to the support frame, the conditioning device positioned in a downstream direction from the clean side of the filter media with respect to the stream of air, the conditioning device offset from the clean side of the filter media by a separation distance.

Engine air precleaner system

An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.

HIGH PERFORMANCE DENSITY ELEMENT WITH ANGLE BETWEEN INLET FLOW AND OUTLET FLOW

Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.

Air intake system for an engine

In one example, an air intake system is provided. The air intake system includes a first air inlet duct providing intake air to an engine intake conduit, the first air inlet duct including an opening positioned external to an engine compartment. The air intake system also includes a second air inlet duct positioned upstream of the engine intake conduit and external to the engine compartment, the second air inlet duct including a porous material spanning an opening in the second air inlet duct, the porous material having a plurality of defined openings sized to prevent snow from traveling therethrough and collect on the porous material thereby impeding airflow through the second air inlet duct during snowy and icy conditions.
