摘要
在一台S1100A2型单缸柴油机上,通过在柴油中添加乙醇、甲缩醛(DMM)、碳酸二甲脂(DMC)等3种含氧添加剂,研究了在常用工况下混合燃料的含氧量对柴油机排放特性的影响。试验结果表明,含氧混合燃料可以有效改善柴油机的烟度和CO排放,在大负荷下尤为明显,而对NOx和HC的排放影响较小。
With a single-cylinder diesel engine,through adding the oxygen containing additives,i.e.alcohol,dimethonymethan （DMM）and dimethyl carbonate （DMCJ）,influences of oxygen contents of blend fuels on diesel engine emission performances under typical operating conditions were studied.Test results indicate that oxygen containing blended fuels can effectively improve smoke and CO emission of diesel engines,especially under great load,however it has less influence on NOx and HC emissions.
