    摘要: A filter (10), including an inside-out reverse flow air filter, has an annular filter element (20) with an upper end cap (24) provided by a resiliently compressible trifunctional member having: (a) a wall (50) deflecting debris radially outwardly within the housing away from the central opening (26) of the hollow filter interior (22); (b) an air entrance guide throat (52) directing air to the central opening (26) with reduced restriction; and (c) a sealing surface (54) sealed to the housing and blocking air flow from the inlet (28) to the outlet (34) otherwise bypassing the filter element. In further embodiments, simplified and cost reduced sealing is provided by a configured end cap.

    摘要: An apparatus for reducing crankcase emissions generated by an engine is described. The apparatus generally includes a separator that removes particulate matter from the crankcase emissions and a treatment component that removes odor and gases from the crankcase emissions. The apparatus is configured where the treatment component is disposed downstream of the separator, the separator first removes particulate matter from the crankcase emissions and the treatment component then removes odor and certain gases from the crankcase emissions.
