| Abstract: | A model for simulating the vehicle exhaust catalyst′s performance is put forward, which includes the relationship between cata lyst′s conversion efficiency and inlet temperature, the relationship between catalyst′s conversion efficiency and A/F ratio,as well as the effluence of space velocity on conversion efficiency and light off temperature. Formula for calculating parameters such as clear cross section,internal surface area and pressure drop in catalyst′s substrate are also presented.Finally methods for analyzing the catalyst′s performance and the catalyst′s durability in practice are introduced. |
