| Abstract: | This paper describes the effect of fast aging and evaluation conditions on catalytic converter performance (mainly the light-off temperature and conversion efficiency). Based on a homemade catalytic converter and a SANTANA 2000 Gsi car the effect of fast aging duration on catalytic converter performance is studied. The results show it's a typical performance when the converter is aged for 30h. A few conclusions and suggestions are given based on the test data. |
