摘　　要：阐述了SCR系统的工作原理及其组成,对尿素泵根据指令喷射出的尿素水溶液进行测量,并将实际喷射量与预期喷射量进行对比,计算相对误差,验证尿素泵的控制精度。试验结果表明,利用开环控制策略下的尿素泵能达到SCR系统工作要求。The principle of SCR system and its components were firstly introduced in this paper. Secondly, corresponding aqueous urea solutions were measured jetted from urea pump based on instruction, and it calculated the relative error by the comparison between actual emitted dose and expected emitted dose, which tested the control precision of urea pump. The result of test showed that the SCR system can meet the demands of working by the strategy of open-loop control.
