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.

Hydrocarbon adsorber for air induction systems

An inlet conduit for an engine air induction system is provided, the inlet conduit having a plurality of openings located about a portion of the inlet conduit, the plurality of openings being disposed in a cavity of the inlet conduit; a hydrocarbon vapor-adsorbent member disposed in the cavity, the hydrocarbon vapor-adsorbent member covering the plurality of openings; and a covering member secured to the inlet conduit, the covering member being configured to cover and seal the hydrocarbon vapor-adsorbent member within the cavity, the covering member having an interior surface and an exterior surface, the interior surface facing the hydrocarbon vapor-adsorbent member while the exterior surface is flush with an exterior surface of the inlet conduit when the covering member is secured to the inlet conduit and 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.
