摘　　要：基于某款国六重型柴油机,搭载全流发动机台架,分别采用3种不同典型硫含量的柴油,对比世界统一瞬态循环(WHTC)下NO_(x)、HC和CO排放的差异。结果表明:随着柴油含硫量的升高,NO_(x)排放量也会显著升高,但HC、CO的排放量一直维持在较低水平,无明显变化。Based on a ChinaⅥheavy-duty diesel engine equipped with a full-flow engine plat⁃form,three kinds of diesel with different typical sulfur contents were burned respectively,and the differ⁃ences of NO_(x),HC and CO emissions under the world uniform transient cycle(WHTC)were compared.The results show that with the increase of diesel sulfur content,NO_(x)emission will also increase signifi⁃cantly,but HC and CO emissions have been maintained at a low level without significant change.
