Abstract
A simplified method was developed to obtain three-way catalyst performance data to be used for predicting vehicle CVS-H emissions. This method involves engine dynamometer aging of catalysts and characterization of their performance as a function of four variables, namely, redox potential, temperature, space velocity and a modulation parameter. In the process of reducing the number of variables, several simplifications were made. The simplifications, their limitations and the characteristic trends in the performance of a 11 Pt/Rh catalyst are discussed.
