    Abstract: A removable and replaceable end cap that selectively lockingly engages a seat ring of a filter housing. The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element. The filter element, which may be coupled to the end cap, may be adapted to remove particulate or contaminate from the received fluid.

    Abstract: A dosing and mixing arrangement includes a mixing tube having a constant diameter along its length. At least a first portion of the mixing tube includes a plurality of apertures. The arrangement also includes a swirl structure for causing exhaust flow to swirl outside of the first portion of the mixing tube in one direction along a flow path that extends at least 270 degrees around a central axis of the mixing tube. The arrangement is configured such that the exhaust enters an interior of the mixing tube through the apertures as the exhaust swirls along the flow path. The exhaust entering the interior of the mixing tube through the apertures has a tangential component that causes the exhaust to swirl around the central axis within the interior of the mixing tube. The arrangement also includes a doser for dispensing a reactant into the interior of the mixing tube.

    Abstract: Air filter cartridges for use in air cleaner assemblies are described. The air filter cartridges typically comprise a stack of strips of fluted media, having an inlet flow face and an outlet flow face. A projection is provided extending outwardly from adjacent the outlet flow face of the media pack, as a projection supporting a seal arrangement. The seal arrangement is typically rectangular, with four straight and four rounded corners. The projection can be configured with open corners, and in some instances comprises tabs, to facilitate flexing of the projection to accommodate variations in a housing seal surface, with which the cartridge is installed. Air cleaner assemblies and components therefor, using cartridges in accord with the descriptions herein, are described.

    Abstract: Pleated filtration media, media packs, filter elements, and methods for filtering fluid are provided which contain three dimensional tapered flutes in the media surface, the flutes configured to improve filter performance. In certain embodiments the flutes have defined peaks that reduce masking between adjacent pleats, the flutes have ridges along their length to modify flute cross sectional geometry, and/or the flutes provide for volume asymmetry across the media.

    Abstract: Liquid filter assemblies, features, components and methods are described. In general, a liquid filter cartridge is provided which includes features that help ensure that when the assembly is serviced, the cartridge positioned within the assembly is a proper one, in proper sealing orientation, for appropriate use. Features that can be used to provide for this include: a seal on the filter cartridge that defines a seal pattern non-orthogonal to a plane perpendicular to a central axis of the filter cartridge; and, a member of a projection/receiver arrangement on the filter cartridge which is orientated to engage a portion of a liquid filter assembly, for example a liquid flow collar, to allow sealing when the cartridge is a properly positioned cartridge and a properly configured cartridge. Assembly features are described. Also, a flexible radial projection arrangement providing snap-fit interaction between a cartridge and housing is provided. Methods of assembly and use as described.
