摘　　要：在186FA柴油机上,进行了燃用柴油、生物柴油和甲醇—生物柴油混合燃料的性能试验,分析了生物柴油掺烧甲醇对柴油机性能的影响规律。试验结果表明:与燃用生物柴油相比,生物柴油掺烧5%和10%(质量比)的甲醇时,柴油机的标定功率分别降低7.4%和17.8%,标定工况时能量消耗率增加5.7%和15.0%,CO排放升高40.0%和80.0%,HC排放升高66.7%和155.6%,NOx排放降低15.0%和33.3%,排气烟度降低3.8%和23.1%。On an 186FA diesel engine,the experiments of diesel,biodiesel and methanol-biodiesel were carried out and the influences of methanol-biodiesel on engine performance were analyzed.The results show that,compared with pure biodiesel,biodiesel blended with 5% and 10%,which refer to the mass ratio,methanol respectively leads to 7.4% and 17.8% decrease of rated power,5.7% and 15.0% increase of brake specific fuel consumption,40.0% and 80.0% increase of CO emission,66.7% and 155.6% increase of HC emission,15.0% and 33.3% decrease of NOx emission and 3.8% and 23.1% decrease of exhaust smoking.
