| 摘 要： | 利用GT-Power软件建立DPF喷油催化燃烧再生系统仿真模型,从喷油率和补气策略两方面对DPF提温过程进行优化,优化后的DPF提温时间缩短了37.9%,DPF出口最高温度增加了3.4%.通过建立DPF微粒燃烧模型,分析了再生微粒燃烧过程中载体壁面温度及微粒(PM)层厚度分布情况.计算结果表明,载体温度由前端向后依次升高,最高温度出现在载体后端中心;微粒由载体前端向后逐渐燃烧,后端微粒燃烧速度快于前端.

| Abstract: | A DPF catalyst regeneration simulation model is established and simulated by GT-Power software package. The regeneration process has been optimized in view of the strategies of injection rate and auxiliary air. After the optimization, DPF heating time has been shorten by 37.9%,and the maximum outlet temperature has been increased by 3.4%. The PM combustion model of DPF is set up to analyze the temperature of filter and thickness of PM layer during regeneration process. The calculation results indicate that the temperature is gradually increasing from the front end to the back end of the filter and the maximum temperature appears at the center of back end. The PM is gradually burning from the front end to the back end of filter,and PM at the back end burns faster than that at the front end. |
