| 摘 要： | 为研究车用尾气催化剂在实际使用中的工作性能，本文建立了用于模拟车用尾气催化剂的转化率－温度特性模型，以及空速对转化率影响的计算模型，利用上述模型可根据不同车辆行驶工况下催化剂的人口温度以及空速情况，计算出相应工况下的催化转化率，这样还可为催化剂的设计提供指导。此外，本文还讨论了所建模型的限制之外。

| Abstract: | In order to study the performance of vehicle exhaust catalyst under different driving conditions, a model for vehicle exhaust catalyst is put forward, which could simulate the catalyst's performance of conversion efficiency vs temperature curve. Formula for calculating effluence of space velocity on conversion efficiency is also provided. By using above model, the conversion efficiency could be calculated on the basis of inlet temperature and space velocity under different driving conditions. Furthermore the limitation of this model is discussed. |
