ABSTRACT:
An evaporative emissions filter for an engine air induction system. The evaporative emissions filter includes a hydrocarbon vapor-adsorbent member disposed within the air induction system. Hydrocarbon vapors present in the air induction system after engine shut-down are substantially retained in the adsorbent member until air flows through the air induction system after the engine starts.
