Abstract: A filter assembly comprises a housing open at one end and holding a filter element therein and a plate closing the open end of the housing and enclosing the filter element within the housing. The plate includes at least two first inlet openings, at least two second inlet openings, and a central outlet opening. The filter assembly further includes a fluid flow controller disposed between an end of the filter element and the plate. The flow controller includes a relief valve comprising a first portion cooperating with the first inlet openings and a second portion cooperating with the second inlet openings; and biasing means operatively connected to the relief valve and providing resistance to movement of the second portion of the relief valve.

Abstract: An inlet conduit for an engine air induction system, comprising: a plurality of openings located about the inlet conduit; a hydrocarbon vapor-adsorbent member disposed on an exterior surface of the inlet conduit, the hydrocarbon vapor-adsorbent member covering the plurality of openings; and a covering member secured over the hydrocarbon vapor-adsorbent member, the covering member sealing the hydrocarbon vapor-adsorbent member to the inlet conduit, wherein hydrocarbon vapors present in the air induction system after engine shut-down are substantially retained in the hydrocarbon vapor-adsorbent member until air flows through the air induction system after the engine starts.
