Experimental Research on Oxygen-enriched Air Supply System for Gasoline Engine

The paper designs and establishes a set of membrane oxygen-enriched air supply system. Experimental research is conducted for LTV-PS roll-type oxygen-enriched membrane module, results of which show that oxygen-enriched concentration is on the rise with the increase of pressure and air flow. Under normal operating temperature, the concentration of O2 in membrane enriched air can reach 28.3 % when the operating pressure and air flow are respectively 102.7 kPa and 24 m3/h
