Patent ID: 8277546

Claim:
A hydrocarbon adsorption trap for adsorption of hydrocarbon vapors within an air intake tract, comprising: a hydrocarbon vapor adsorbent member including: two or more media retention layers, wherein media retention layers are arranged in a spaced proximate facing relationship, wherein said media retention layers are formed by one or more media retention sheets; and wherein adjacent pairs of said proximately arranged facing layers form at least one gap therebetween; a granular hydrocarbon vapor adsorbent media arranged in said gap, wherein said media retention layers close about said gap to supportively retain said granular hydrocarbon vapor adsorbent media therein; wherein said granular hydrocarbon vapor adsorbent media is arranged in proximity to a major portion of a media facing surface of said media retention layers, said media retention layers configured to supportively retain said granular hydrocarbon vapor adsorbent media positionally proximate to said media facing surface; wherein said hydrocarbon adsorbent media is adhesively secured to at least one of said media retention layers; an air permeable media support body including: a first support member including a first media receiving area sized and adapted to supportively receive a first face of said hydrocarbon vapor adsorbent member, said first support member overlaying and extending across said first face; and a second support member including a second media receiving area sized and adapted to supportively receive an opposing second face of said hydrocarbon vapor adsorbent member, said second support member overlaying and extending across said second face; wherein said first and second support members are configured and adapted to supportively retain said hydrocarbon vapor adsorbent media therebetween.
