1、基于不同燃油品质的内河船舶排放特性试验研究楼狄明，施利华，胡志远，谭丕强（同济大学汽车学院，上海201804）摘要：采川车载排放测试系统，对某内河船舶于苏州河某航段进行丫分别燃用B0（纯石化柴油）和B10（生物柴油-柴油混合燃料，生物柴油体积比10%）的实船放对比试验，探究丫燃油品质对内河船舶PN（颗粒物数量）、CO、THC和NOX排放的影响，结果表明：①内河船舶燃川B0和B10时的PN随粒径分布相似，在离港、进港和低发动机负荷工况时呈双峰对数分布，在巡航及中、高发动机负荷工况时呈单峰对数分布；©内河船舶燃用B0和B10时，PN、
2、THC、NOX排放均随负荷变大而升高，而CO排放则先降低后升高；③内河船舶燃用B10时PN、CO和NOX排放因子相对B0有所降低，离港、巡航、进港时PN排放因子分别降低13.82%、8.21%、46.44%,CO排放因子分别降低20.87%、12.66%、7.52%,NOX排放因子分别降低21.91%、21.63%、39.20%,B10的THC排放因子高于B0,离港、巡航、进港时分別提高33.68%、20.46%、26.62%。关键词：内河船舶；燃油品质；排放特性；车载排放测试系统中图分类号：U661.43文献标识码：AExper
