基于车用催化剂热失活机理，在发动机台架和 R － FOCAS 台架上分析不同的老化方法对催化剂劣化强度的影响。利用断油和 ARL －102老化循环对四只相同的催化器样件进行50h 的快速老化试验。通过老化后催化剂性能测试，依据催化剂劣化强度的评价指标考察三效催化剂性能的变化。

Based on the mechanism of automotive catalyst deactivation at high temperature ,different ag-ing method effecting on catalyst deactivation degree between engine and R - FOCAS bench is analyzed in this paper .An 50h accelerated aging experiment on the same four catalytic converter was carried out between engine and R .FOCAS bench using fuel - cut and ARL - 102 method .After the performance e-valuations of aging catalyst ,changes in performance of the three - way catalyst were observed according to the evaluation method of deactivation degree for catalyst .
