A flame-retardant hydrocarbon adsorption trap is adapted for mounting within an air intake tract. The traps includes a hydrocarbon vapor adsorbent media adapted to adsorb hydrocarbon vapors from an intake tract when an engine is not operating then later releasing the vapors when the engine runs. The trap includes at least two air permeable HCA media retention layers positioned in a spaced parallel relationship and forming a gap there-between into which hydrocarbon vapor adsorbent media is received. The retention layers are formed of a synthetic fiber media adapted to provide flame-resistant properties. |
