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.
