Abstract:
1. An evaporative emissions filter for an engine air induction system having a direct air flow path, the air induction system including a housing containing an air filter, the evaporative emissions filter comprising: a hydrocarbon vapor-adsorbent member disposed within the air induction system substantially outside of the direct air flow path, and disposed above the direct air flow path, wherein the hydrocarbon vapor-adsorbent member is disposed only on a portion of a section of the air induction system defining the direct air flow path; and a fastener for mounting the evaporative emissions filter within the air filter housing; wherein 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.
