Abstract :
An oxygen-enriched intake air system (OIAS) which based on the gas membrane separation technology was built. The experimental study of hydrocarbon (HC) emissions of gasoline engine was conducted by using this OIAS. The results show that the OIAS can provide the oxygen-enriched intake air with 21%, 23%, 25%, 27% and 29% oxygen (O2) concentration. Within the first 60 seconds of -7°C cold-start, after using OIAS, the HC emissions of gasoline engine reduced obviously, the maximum reduction is 79%. The result shows that OIAS is equipment which can reduce HC emissions of gasoline engine during -7°C cold-start effectively.
