Abstract:
1. A hydrocarbon adsorption trap for adsorption of evaporated fuel vapors within an air intake tract of an internal combustion engine, comprising: a first fuel vapor permeable media retention layer; a second media retention layer positioned in a spaced parallel relationship to said first layer forming a gap therebetween, wherein at least one of said layers is a woven or non-woven synthetic fiber sheet; a hydrocarbon vapor adsorbent media disposed in said gap between said first and second layers for adsorbing evaporated fuel vapors from said intake tract when said engine is not operating, wherein said first and second layers and said adsorbent media form a flexible sheet-like hydrocarbon adsorption trap; and a mounting member secured onto and overlaying peripheral edge portions of said first and second layer and projecting outwards beyond said first and second layers, said mounting member sealing said gap at said layer edge portions, operatively closing edges of said gap, retaining said adsorbent media between said layers; wherein said mounting member circumferentially extends along, secures and closes over at least one of said edge portions of said layers, wherein said mounting member includes a mounting lip arranged on opposing sides of said trap, said mounting lip arranged outwardly beyond said first and second layers, said mounting lip having at least one through-hole extending therethrough, wherein said mounting lip having said at least one through-hole is configured and adapted for mounting said adsorption trap within said air intake tract.
