Abstract
A hydrocarbon adsorption assembly for an air induction system is disclosed. The hydrocarbon adsorption assembly includes a fluid conduit having an outer surface and a spaced apart inner surface to form a fluid path therein, the conduit including a recessed area formed in the inner surface thereof. A hydrocarbon trap is disposed in the recessed area of the fluid conduit to adsorb hydrocarbons passing through the conduit. The recessed area and the hydrocarbon trap cooperate to cause a portion of an air flowing through the flow path of the conduit to flow through the hydrocarbon trap to facilitate a purging thereof.
