摘要
利用GT-power软件对氧化催化转化器(DOC)建立模型并进行模拟仿真,得出了DOC主要结构参数流通截面积、载体长度与CO,HC转化率及背压的关系。通过试验验证了仿真模拟可行有效,CO,HC转化率和背压的模拟计算与试验结果较吻合。
In this paper, model of Diesel Oxidation Catalyst （DOC） is founded and simulated by GT-power software. DOC simulation has obtained the relationship between main design parameter Flow Area of the Catalyst and carrier length and CO, HC conversion rate and back pressure. Simulation of DOC model is feasible and effective through the experiment. Simulation results have a good agreement with experimental results on conversion rate of CO, HC and back pressure.
