Summary:A hydrocarbon adsorption unit for recovery of volatile hydrocarbons which emanate from several sources and which would otherwise be released into the atmosphere through the air cleaner of an automobile engine when the engine is shut­ off. The unit is positioned in the air intake system such that all air flowing through the engine passes through the unit. The unit comprises a housing having an air inlet and an air outlet. The housing contains a substrate and a volatile hydrocarbon adsorber material coated on the surface of the substrate. The adsorber material may be silica gel, a molecular sieve and/or activated carbon. The material further contains a binder that will cause the material to adhere to the surface of the substrate. L'invention concerne un module d'absorption d'hydrocarbures permettant de récupérer des hydrocarbures volatiles qui émanent de plusieurs sources et qui pourraient être rejetés dans l'atmosphère par le biais d'un filtre à air d'un moteur automobile, lorsque le moteur est arrêté. Ce module est placé dans le système d'admission d'air, de telle manière que tout l'air s'écoulant à travers le moteur passe à travers le module. Ce denier comporte un logement pourvu d'une admission d'air et d'une sortie d'air. Ledit logement comprend un substrat et une matière d'absorption d'hydrocarbures volatiles recouvrant la surface du substrat, la matière d'absorption pouvant être un gel de silice, un tamis moléculaire et/ou un carbone activé. Cette matière renferme également un liant qui permet à la matière d'adhérer à la surface du substrat.
