摘 要: | 为了解不同影响因素对氮氧化物选择性催化还原开环控制技术误差的影响程度,推导氮氧化物选择性催化还原开环控制技术误差的理论表达式,试验表明原机排放相对误差对氮氧化物选择性催化还原开环控制技术误差的影响比尿素水溶液浓度相对误差和计量装置相对误差产生的影响大。

Abstract: | In order to understand the effect of different relative factors on an open-loop controlled SCR System,an expression on the system error was deduced,and a conclusion that NOx estimation error has a more important effect than the concentration error and the dosing error does was observed with the additional examination data. |
