Abstract
A hydrocarbon adsorption trap for adsorption of evaporated fuel vapors includes a first fuel vapor permeable media retention layer, a second media retention layer positioned in a spaced parallel relationship to the first layer forming a gap therebetween and a hydrocarbon vapor adsorbent media disposed in the gap between the first and second layers for adsorbing evaporated fuel vapors from the intake tract when the engine is not operating. A mounting member is secured to peripheral edge portions of the layers and closes the gap between the layers while providing a means of securing the trap into an air intake tract.
