摘要
本文对车用尿素水溶液中不溶物产生的原因进行了分析,又对GB 29518-2013《柴油发动机氮氧化物还原剂 尿素水溶液(AUS 32)》附录E不溶物含量检测方法中仪器和设备、样品准备、测量3部分进行检测参数优化,使不溶物含量检测结果的重复性更好。In this paper, the causes of insoluble matter in vehicle urea aqueous solution were analyzed, and the detection parameters of instrument and equipment, sample preparation and measurement in Appendix E of GB 29518-2013 “Diesel engine NOx reduction agent—Aqueous urea solution (AUS 32)” in the insoluble matter content detection method were optimized. The repeatability of insoluble content detection results is better.
