    摘要: An underhood air cleaner (20) for a vehicle (22) has an inlet shroud seal (72) self-mounted to the filter housing (60) at the filter inlet (68) and engaging the hood (28) at the exit opening (36) of the hood air channel (30). The self-mounting is accomplished without extra parts or fasteners such as bolts and clamps. Both axial (198) and radial (200) retention is provided for the shroud seal (72) on the filter housing (60), as well as reduced inflow restriction.

    摘要: An air filter housing (12) includes twist and lock structure (46) having a first position (FIGS. 5, 6) permitting axial movement (120) of a cover (44) and base (38) relative to each other, and being rotatable in a first direction (48) from the first position (FIG. 6) to the second position (FIG. 7), and in the second position (FIG. 7) preventing axial movement of the base (38) and cover (44) relative to each other, and being rotatable in a second opposite direction (78) from the second position (FIG. 7) to the first position (FIG. 6). Anti-rotation lock structure (80) provides a rotational retention force holding the twist and lock structure (46) in the second position (FIG. 7).

    摘要: A dual stage coalescer includes a separator in a separator chamber separating gas and liquid by inertial impaction, and a coalescer filter element in a coalescer chamber separating gas and liquid by coalescence. A transfer tube extends between the separator chamber and a downstream subchamber in the coalescer chamber at the downstream face of the coalescer filter element, and supplies pre-separated liquid from the separator chamber through the transfer tube to the noted downstream subchamber as driven by pressure differential between the separator chamber and the downstream subchamber, to eliminate a dedicated housing drain outlet from the separator chamber. The coalescer may provide a crankcase ventilation filter for an internal combustion engine having blowby gas containing an air-oil mixture.
