摘要
针对于TBD234V6 型船用柴油机,利用AVL-Fire仿真软件,对额定工况下燃用纯柴油、生物柴油与乙醇不同掺混比的混合燃料的柴油机进行仿真试验研究,通过分析船用柴油机的燃烧性能与排放性能,探究乙醇对掺烧30%掺混比例生物柴油的船用发动机性能的影响.结果表明:当乙醇在柴油-生物柴油混合燃料中掺混比例达到20%时,缸内的爆发压力与温度峰值下降的幅度最大,NOx与Soot的排放量也显著降低,相较于柴油-生物柴油混合燃料燃烧,缸内的爆发压力与温度峰值分别降低了约1.7%与2.9%,NOx的排放量降低了19.9%,Soot的排放量降低了18.5%.
Abstract
For the TBD234V6 marine diesel engine,AVL-Fire simulation software was used to conduct simulation experiments on diesel engines using a mixture of pure diesel,biodiesel,and ethanol with different blending ratios under rated operating conditions.By analyzing the combustion and emission performance of marine diesel engines,the influence of ethanol on the performance of marine engines with 30%blending ratio of biodiesel was explored.The results showed that when the blending ratio of ethanol in diesel biodiesel mixed fuel reached 20%,the peak pressure and temperature in the cylinder decreased the most,and the emissions of NOx and Soot were also significantly reduced.Compared with the combustion of diesel biodiesel mixed fuel,the peak pressure and temperature in the cylinder decreased by about 1.7%and 2.9%,respectively,and the emissions of NOx and Soot decreased by 19.9%and 18.5%,respectively.
