摘　　要：选择满足国Ⅴ排放标准的中型车用柴油机,燃用国六标准的车用柴油和柴油添加剂开展台架试验,评价了“老机烧新油”的污染排放及使用添加剂的影响。研究表明:“老机烧新油”可以达到排放限值要求,加入柴油添加剂对污染物排放影响有限,部分指标下降的同时其他指标略有上升,总体可满足当前排放标准。加入柴油添加剂可显著降低柴油机喷嘴沉积物,有较好的抑制喷嘴结焦堵塞的性能;同时有较明显的提升动力性能和降低油耗的效果。Our group select medium-sized vehicle diesel engines that meet the National V emission standards,and use National VI vehicle diesel and diesel additives to carry out bench tests,reflecting the phenomenon of“old engines burning new oil”.Studies have shown that“old engine burning new oil”can meet the emission limit requirements.The addition of diesel additives can have a limited impact on pollutant emissions.Some indicators have declined while other indicators have risen slightly,which can generally meet current emission standards.Adding diesel additives can significantly reduce the deposits of diesel engine nozzles,and has better performance in inhibiting nozzle coking and clogging;at the same time,it has obvious effects of improving power performance and reducing fuel consumption.
