Patent ID: 8273163

Claim:
A flame-retardant hydrocarbon adsorption trap for adsorption of hydrocarbon vapors within an air intake tract, comprising: a hydrocarbon vapor adsorbent media for adsorbing hydrocarbon vapors from said intake tract when an engine is not operating then releasing said vapors when said engine runs; and at least two air permeable HCA media retention layers positioned in a spaced parallel relationship and forming a gap there-between into which said hydrocarbon vapor adsorbent media is received, wherein said retention layers include synthetic fiber media, said fiber media has flame-proof or flame-resistant properties; wherein said trap is adapted for mounting into said air intake tract; wherein at least one of said retention layers is a woven or non-woven sheet of synthetic fibers; wherein retention layers and said hydrocarbon vapor adsorbent media form a flexible sheet-like hydrocarbon adsorption trap; a mounting member secured to peripheral edge portions of said media retention layers and projecting outwards therefrom, 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 includes a mounting lip arranged on opposing sides of said trap; wherein said mounting member is configured and adapted for supportively mounting said adsorption trap within said air intake tract; wherein said mounting member has flame-resistant properties.
