| Abstract: | A model for simulating the vehicle exhaust catalyst's performance is put forward,which includes the relationship between catalyst'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'ssubstrate are also presented. Finally methods for analyzing the catalyst's performance, the catalyst's durability and causes of deactivity in practice are introduced. |
