| Abstract: | A multi rapid aging cycle, which is widely used abroad, was used to develop the theory and technology for testing automotive catalysts in China. The locally produced low precious metal three way catalysts (TWC) was evaluated by this method and the fuel cut method. The new mode mechanism and its comparison with other modes have not been reported till now. The results show that the multi stage aging cycle has both deactivation effects of high temperature oxidation and cyclical rich lean air/fuel ratio shocking. The mode has a higher aging intensity than the fuel cut aging mode. |
