摘要
DPF作为柴油机尾气后处理技术的关键部分,国内外学者对其一直有大量研究。本文研究了在2500r/min、75%负荷下DPF对柴油机不同粒径的PM捕集效果,研究结果表明,随着试验时间的延长,DPF对柴油机PM的捕集率有所提高,且DPF对大粒径聚集态颗粒物的捕集率要高于对核态颗粒物的捕集率。
DPF is a key part of diesel exhaust post-treatment technology,which has been studied extensively by domestic and foreign scholars.In this paper,the capture effect of DPF on PM of diesel engine with different particle sizes was studied under 2500 r/min and 75%load.The results show that,with the extension of test time,the capture rate of DPF on PM of diesel engine is improved,and the capture rate of DPF on large particle size aggregated particles is higher than that on nuclear particles.
