摘要:
An emission control device for an air induction system of an internal combustion engine having high adsorption capacity, yet low flow resistance is disclosed. The AIS emission control device comprises a first case including an outlet-opening connected to an intake manifold of the engine; a second case including an inlet-opening for the intake air; and an adsorbent element positioned in a plane across the intake airflow, wherein the adsorbent element has an opening area such that the control device has a pressure drop of less than about 1 inch H2O at the air flow rate of about 300 cfm and % reduction in vapor emission of at least about 75% after one day of the vapor generation rate of about 220 mg/day.
