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.
