建立了在铁交换沸石催化剂上NH3- scr过程的详细模型，该模型考虑了典型排气条件下NH3、NO和no2的反应。标准SCR气体混合物的验证实验表明，该模型能够描述该系统在瞬态温度条件下的动态行为。该模型用于氨加药控制器的参数化。为验证该控制器的功能，在合成气试验台上实现了该控制器，并进行了动态温度实验。这种设置允许参数化控制器的评估没有任何干扰从发动机或喷射效应。
The setup of a detailed model for the NH3-SCR process on iron exchanged zeolite catalysts is described, which takes into account the reactions of NH3, NO and NO2occurring under typical exhaust conditions. Validation experiments for a standard SCR gas mixture show that the model is able to describe the dynamic behaviour of this system at transient temperature conditions. The model is used for the parameterization of an ammonia dosing controller. To prove the functionality of this controller it was implemented on a synthetic gas test bench and tested by a dynamic temperature experiment. This setup allows the evaluation of the parameterized controller without any disturbances from engine or injection effects.
