摘　　要：在一台直喷式涡轮增压柴油机上分别燃用4种不同含硫量的柴油,研究了燃油含硫量对柴油机排放特性的影响。研究结果表明,随着燃油含硫量的降低,柴油机的HC、CO和烟度排放按所列顺序明显下降;NOx排放也随燃油含硫量的降低而下降,但变化很小;SO2排放随柴油机负荷的增加显著上升,随燃油含硫量的降低而显著下降,表明燃油含硫量与柴油机SO2排放之间有高度相关性。A direct injection turbocharged diesel engine, fueled with four diesel fuels with different sulfur content is tested to study the effects of sulfur content in the fuel on the emission characteristics of diesel engine. Resuits show that with the reduction of sulfur content in the fuel, HC, CO and smoke emissions markedly decrease in that order; NOx emission also reduces with the decrease in sulfur content, but having only minor changes; while SO2 emission obviously rises with the increase in engine load and apparently decreases with the drop in sulfur content, showing high correlation between sulfur content and SO2 emission.
