摘　　要：建立了基于AVL Fire的WP10.340E32柴油机喷雾和燃烧的仿真模型,研究供油提前角对柴油发动机燃用B20生物柴油-柴油混合燃料时扭矩、燃油消耗率和NOx排放量的影响。研究表明,随着提前角的增大,发动机扭矩逐渐增大,动力性增强;燃油消耗率略有降低;NOx排放量有所增加。Established the simulation model of spray and combustion of diesel engine based on AVL Fire, the influence of the fuel supply advance angle on the torque,specific fuel consumption and NOx emissions of diesel engine fueled with B20 biodiesel-diesel blend was analyzed.Research shows that,with the increase of advance angle,engine torque increases gradually,dynamic enhancement;Specific fuel consumption is slightly lower;NOx emissions significantly increased.
