摘要:
基于D30 TCI柴油机搭建国6后处理系统的试验台架,进行了不同碳载量下CDPF被动再生平衡点温度试验,研究了入口温度对CDPF被动再生的影响;探究了发动机DTI工况下CDPF主动再生特性并测评了其对载体捕集特性的影响。结果表明:碳载量对CDPF被动再生平衡点温度无明显影响,碳载量的升高可提高载体内部温度的均匀性,加快CDPF被动再生反应速率;入口温度对CDPF被动再生具有显著影响,入口温度由325提高至360 ℃时,再生效率达94%,再生速率为56 g/h,分别约提高1倍和18倍;DTI工况下CDPF主动再生时载体内部温度会出现“尖峰”现象,载体内部温度及温升速率在其后段中心处达到峰值;CDPF经多次DTI主动再生后其PM捕集效率无明显影响,但会导致PN捕集效率下降;4种排气污染物(HC、CO、PM、PN)在WHTC测试循环中均满足国6排放法规限值要求。
