摘　　要：通过试验对SCRF进行特性研究,并通过逐步积碳做背压试验,研究SCRF与背压的关系;通过整体布置,研究温度对SCRF的影响;通过在不同碳载量下喷射尿素,研究碳载量与尿素转化效率的关系;在SCRF满碳状态下,分别设定喷尿素和不喷尿素情况,逐渐提高SCRF温度,研究尿素对被动再生影响;将SCRF积碳到不同程度下,计算箱体内的氨储,研究碳载量与氨储的关系。在试验完成后,整理试验数据,并分析理论与试验结果,按照理论指导试验,试验验证理论的指导方针,对SCRF的特性指标进行深度分析。The paper illustrates SCRF character by experiment firstly , and studied the relation of SCRF and backpressure by accumulating soot; at the same time studied the influence of temperature by overall layout; studied the relation of soot load and conversion efficiency by urea mass at different soot load; at the condition of full soot, increasing SCRF temperature and setting the situation of urea injection, studied urea influence on passive regeneration; in different soot mass, calculating NH3 stor-age ,studied the relation of soot load and NH3 storage. Secondly, after finishing the experiment, pro-cessed data and analyzed results by theory and vice versa, deeply analyzed the character index in the end.
