摘要

为了提高NOx传感器的性能，建立了基于电化学模型和扩散模型的NOx泵送电池组合模型。考虑到少量氧气进入第三腔室，部分NO在第二腔室分解，电化学模型中同时考虑了阴极处NO和氧气的反应，扩散模型中还考虑了氧气的扩散和NO的分解。为了在不同气体浓度下验证模型，将传感器安装在设计的测试台上。然后，将仿真结果与试验台的实验数据进行了比较，得到了较好的一致性。此外，还分析了NOx抽吸池模型中的三个关键参数。文中给出了这三个参数的取值及其变化趋势。

Modeling and analysis of pumping cell of NOx sensor – Part II: NOx pumping cell

To improve the performance of the NOx sensor, a combined model based on the electrochemical model and the diffusion model is developed for the NOx pumping cell of the NOx sensor. Considering that a small amount of oxygen enters the third chamber and part of NO is decomposed in the second chamber, the reactions of both NO and oxygen at cathode are taken into account in the electrochemical model, and the diffusion model additionally takes the diffusion of oxygen and the decomposition of NO into consideration. To validate the model at different gas concentrations, the sensor is mounted on the designed test rig. Then, the simulation results are compared with experimental data from the test rig and good agreement is obtained. In addition, three key parameters in the model of the NOx pumping cell are analyzed. The values and changing trends of these three parameters are given in the paper.
