专家长期研究的结果表明,在纯氨、氮基甲酸铵和尿素溶液(AdBlue)中,尿素溶液是最容易转换的,因此最后规定32.5%的尿素水溶液为SCR系统的还原剂。目前SCR系统中的尿素计量系统已经成熟,加注站等后勤设备也已开始建设。为什么要选择32.5%的尿素溶液呢?主要是因为这个浓度时尿素溶
The result of expert’s long-term research shows that urea solution is the most easily convertible in pure ammonia, ammonium azide and urea solution (AdBlue), so the final requirement is that 32.5% urea solution is the reducer for SCR system. At present, the urea measurement system in the SCR system has matured, and logistics equipment such as filling stations have also started to be constructed. Why choose 32.5% urea solution? Mainly because of the concentration of urea dissolved
