摘要

基于车用催化剂的老化机理，建立车用催化剂综合性能试验台架，对催化剂进行160 h的快速老化，比较其老化前后的性能，分析催化剂台架快速老化和实车道路老化的工况法排放结果及相关性.试验结果表明：催化剂经160 h的台架快速老化后，对CO、THC、NO

的起燃温度分别上升了38.5%、28.4%和37.3%；装有160 h台架快速老化后的催化剂相比于装有160 000 km实车老化后的催化剂的整车工况法排放，其THC、CO、NO

和NMHC的排放结果分别增加了8.6%、11.3%、3.8%和13.7%.

Abstract

Based on the aging mechanism of automotive catalyst

a comprehensive performance test bench for automotive catalysts is established to have a 160-hour accelerated aging on the catalyst. The performance of catalyst before and after accelerated aging is compared

and an analysis of correlation and emission by European test cycle for a vehicle after its catalyst being aging on the bench and real vehicle is made. The results show that the light-off temperature of CO

THC

rises by 38.5%

28.4% and 37.3% respectively after rapid aging of the catalyst on the bench for 160 hours. In addition

compared with the real vehicle catalyst aged after 160 000 km

the emission of THC

NMHC among the vehicle with the 160 h-rapid aging catalyst on the test bench increases respectively by 8.6%

11.3%

3.8% and 13.7%.
