A filter cartridge configured to be removably positionable within an inner opening of a housing, wherein the filter cartridge includes a media pack having an inlet end, an outlet end, and an outer surface having an outer peripheral shape, at least one of: (a) a frame member at least partially surrounding the media pack, the frame member including a frame wall having a shape that is different from the outer perimeter shape of the media pack; and (b) a shell at least partially surrounding the media pack, the shell including a shell wall having a shape that is different from the outer perimeter shape of the media pack, and a sealing member extending at least partially around the inlet end of the media pack, wherein the sealing member connects the media pack to at least one of the frame member and the shell.

An air cleaner assembly including a tray including a cleat receptacle at a back side of the assembly and a cover including a cleat at the back side. The assembly further includes guide features arranged at a front side of the assembly. The guide feature are designed to contact one another continuously and guide the cover rearward, from an unseated position to a fully seated position where the cleat is seated within the cleat receptacle.

According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

A circular air filter for vehicle is provided. The circular air filter is mounted in an air cleaner body disposed between an air inlet configured to suction air from an exterior and an air duct configured to provide filtered air to an engine. A frame is formed in a cylinder shape and has a penetration aperture to provide air flow along a circumference thereof. An engaging portion is formed at a first end of the frame and coupled to a first side of the air cleaner body. A non-woven fabric is disposed on an exterior of the frame and is coupled to the engaging portion for filtering foreign materials.

An air cleaner structure for blocking an inflow of debris to prevent the debris from inflowing into an engine intake passage of an air cleaner housing when replacing a filter includes a rotator fixing the filter and a filter cover to the air cleaner housing and generating a rotating force to open and close the engine intake passage. An engine intake passage door opens and closes the engine intake passage by the rotating force of the rotator. A connector has one end connected to the rotator and another end connected to the engine intake passage door to deliver the rotating force to the engine intake passage door.

Air cleaner assemblies, components, features and methods of assembly and use are described. Example air cleaner assemblies are depicted and described in which a main filter cartridge sealing surface is recessed from an open end of a housing body. An access cover of the housing is configured with a portion extending inwardly to engage a main filter cartridge portion and bias it against the main filter cartridge sealing surface. In selected assemblies, the portion of the access cover extending inwardly toward the main filter cartridge, is a precleaner having flow separator tubes therein.

A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

An air cleaner includes a filter element, a case having an opening and being configured to accommodate the filter element, and a lid configured to close the opening. The case includes a wall including a first surface and a second surface that are formed on at least one of an outer surface and an inner surface of the case and are continuous with each other in an opening direction of the opening through intermediation of a stepped portion. The case further includes a rib formed on at least one of the first surface and the second surface to extend in the opening direction.

A vehicle includes an air cleaner box assembly disposed within an engine compartment. The air cleaner box assembly includes a moveable shell portion and a stationary shell portion. The moveable shell portion includes an upper surface disposed adjacent a hood, and defines a filtered air chamber. The stationary shell portion is attached to a structure, and defines an unfiltered air chamber. A filter element is attached to and supported by the moveable shell portion. The filter element separates the filtered air chamber and the un-filtered air chamber. Each of a plurality of spring loaded guide members slideably connect the moveable shell portion and the stationary shell portion, and guide the moveable shell portion along a path relative to the stationary shell portion, between an expanded position and a compressed position.

Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which primary and secondary filter cartridges, having a media pack and a seal arrangement surrounding the media pack, can be installed. The filter cartridges can include an open end cap with an axially deviating seal arrangement and a plurality of axially extending channels for engaging with ribs on the housing. The filter cartridges can also include extension members extending from the open end cap that include the axially extending channels, entirely or partially. The filter cartridges can also include a guide member extending from the extension members for providing a low friction surface against the housing during installation that allows axial force exerted by the installer to be translated into a rotational force that rotates the filter cartridge during installation.
