Abstract
A fugitive hydrocarbon treatment module and system for controlling the emission of hydrocarbons from the air intake system of an engine includes a zeolite adsorber unit positioned in the air intake system such that all gases flowing to and from the engine through the air intake system pass through the adsorber, so as to allow hydrocarbons borne by the gases to be adsorbed upon the substrate of the adsorber unit when the engine is shut down and desorbed from the adsorber unit when the engine is in operation.
