    摘要： FIG. 1 is a perspective view of our new design for a filter cartridge, being shown generally toward an inlet end, and toward a cartridge side.
    FIG. 2 is a first side elevational view of the filter cartridge of FIG. 1.
    FIG. 3 is a second side elevational view of the cartridge of FIG. 1, the view of FIG. 3 generally being toward an opposite side to that viewable in FIG. 2.
    FIG. 4 is third side elevational view taken generally toward the right side of the view of FIG. 2.
    FIG. 5 is a fourth side elevational view of the filter cartridge of FIG. 1, taken generally opposite the view of FIG. 4.
    FIG. 6 is an inlet end plan view of the cartridge of FIG. 1, and taken toward the top of FIG. 1; and,
    FIG. 7 is an outlet end plan view of the cartridge of FIG. 1; the end viewable being opposite FIG. 6.
    In the Figures, dotted lines depict portions of the filter cartridge that form no part of the claimed invention.

    摘要： According to the present disclosure, air cleaner assemblies, components, features, and methods relating thereto, are described. These features, in part, relate to configuration of a preferred seal arrangement and seal surface of the cartridge. Particular arrangements are shown, in which: the filter cartridge includes a seal arrangement having a axial pinch seal surface with a projection/recess contour including at least one projection thereon; and, the cartridge includes a seal contour projection stabilizing portion at a location in perimeter alignment with the portion of the seal pinch arrangement including the first housing engagement projection. Additional features are included that relate to clean air separator section tubes of a precleaner arrangement secured to a cartridge. These features can be used in cartridges including features outlined above, or in alternative cartridges. Additional features of air cleaner arrangements and filter cartridges in accord with the above are described.

    摘要： FIG. 1 is a perspective view of a filter cartridge according to the present design;
    FIG. 2 is a first side elevational view of the filter cartridge of FIG. 1;
    FIG. 3 is a second side elevational view of the filter cartridge of FIG. 1, taken toward an opposite side to that viewable in FIG. 2;
    FIG. 4 is third side elevational view of FIG. 2, taken toward the right side of the view of FIG. 2;
    FIG. 5 is a fourth side elevational view of the filter cartridge of FIG. 1, taken opposite to the view of FIG. 4;
    FIG. 6 is an inlet end plan view, taken toward the top of FIG. 1; and,
    FIG. 7 is an outlet end plan view of the filter cartridge of FIG. 1, the end viewable being opposite FIG. 6.
    The broken lines depict portions of the filter cartridge that form no part of the claimed design. In FIGS. 1-5, the filter cartridge is shown with a symbolic break in its length. The appearance of any portion of the article between the break lines forms no part of the claimed design.
