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 une unité d'adsorption d'hydrocarbures permettant de recycler des hydrocarbures volatils issus de plusieurs sources, qui pourraient être libérés dans l'atmosphère par le filtre à air d'un moteur automobile lorsque ce dernier est éteint. Cette unité est positionnée dans le système d'admission d'air de façon que l'air qui passe dans le moteur traverse ladite unité. Ladite unité comprend un logement qui possède une entrée d'air et une sortie d'air. Le logement contient un substrat et un matériau adsorbant d'hydrocarbures volatils revêtu sur la surface du substrat. Le matériau adsorbant peut être un gel de silice, un tamis moléculaire et/ou un carbone activé. Ledit matériau contient également un liant qui permet de le faire adhérer à la surface du substrat.
