ABSTRACT:
An air intake system for a mobile combustion engine is disclosed. The air intake system comprises a membrane formed from an amorphous polymer of perfluoro-2,2-dimethyl-1,3-dioxole, the membrane exhibiting an oxygen-nitrogen selectivity of at least 1.4:1. Either the permeate section or the feed section of the membrane is adapted to be in fluid flow communication with a combustion zone of the mobile combustion engine. The membrane preferably has an oxygen flus in excess of 100 Barrers, especially in excess of 500 Barrers. The air intake system provides either oxygen-enriched air or oxygen-deplected air for the engine, depending on the mode of operation of the engine.
