摘要
选取了船用生物柴油的部分理化指标如表面张力和粘度对橡胶件及铜片的影响进行了研究,并在YC6J190柴油机上进行了燃用船用生物柴油的台架试验.结果表明,船用生物柴油的掺混比例取0～20%时较为合适.船用生物柴油对橡胶件有溶胀作用,对铜片有腐蚀作用.燃用船用B20混合燃料后,柴油机在全负荷时,有效功率平均下降1.8%;燃油消耗率平均上升0.07%;HC排放平均下降19.17%,排气烟度平均下降25%.在1 500 r/min部分负荷时,HC平均下降23.4%,排气烟度平均下降23%.在自由加速时,炭烟排放平均下降28.8%.
Several physical and chemical indicators of marine biodiesel such as surface tension,viscosity,its influence on rubber and copper were studied in this paper.The bench tests were carried out from a YC6J190 diesel engine fueled with marine biodiesel.The results showed that the proportion of marine biodiesel in the blended fuel should be 0~20%.Marine biodiesel swelled the rubber tube and eroded the copper.When fueled with the B20 marine blended biodiesel,the test results showed that the effective power decreased by 1.8%,the fuel consumption rate increased by 0.07%,HC emissions decreased by an average of 19.17% and the soot decreased by an average of 25% at full engine load.HC decreased by an average of 23.4% and the soot decreased by an average of 23% at part engine load.The soot emissions decreased by an average of 28.8% in the free acceleration condition.
