Abstract:
1. A hydrocarbon trapping device for an air intake system, the hydrocarbon trapping device comprising: a conduit in fluid connection with, and configured to deliver air to, the air intake system, the conduit including a wall having a wall thickness, an inner surface, and a longitudinal axis; and an adsorbing element positioned within the conduit and including a hydrocarbon adsorbing material, the adsorbing element having an adsorbing element thickness generally equal to or less than the wall thickness, the adsorbing element having a leading edge a trailing edge and side edges that define a flow path extending between the leading edge and the trailing edge in a direction substantially parallel to the longitudinal axis; a retainer extending from the inner surface of the conduit and retainingly engaging the side edges of the adsorbing element; wherein the adsorbing element extends substantially completely around an inner perimeter of the conduit adjacent to the inner surface.
