摘      要：The spray characteristics of the blended fuel composed of biodiesel and dimethyl carbonate were compared with those of biodiesel and *** macroscopic spray characteristic parameters including spray tip penetration,maximum spray width,average spray cone angle,and peak tip velocity were used to evaluate the spray characteristics of the blended *** results showed that the spray tip penetration of blended fuel was lower than that of biodiesel,while the spray cone angle and maximum spray width of blended fuel were both larger than that of *** the basis of the Hiroyasu and Arai mathematical model combined with the actual working conditions of this experiment,including physical parameters such as the viscosity and density of the fuel,a correct model of spray penetration was established,and the experimental results were compared.
