摘要：

In this study, spray characteristics of biodiesel blending with di-n-butyl ether (DBE15, DBE30) were investigated by experiment and analysis. Spray characteristics parameters including spray tip penetration and spray cone angle were used to compare the atomization effect under different injection pressures and ambient pressures. The spray tip penetration was logarithmically used to analyze the breakup time and to correct the empirical formula available from literature. The results show that the spray tip penetration of the blends added a certain proportion of di-n-butyl ether was shortened, and the spray cone angle was increased. In addition, the correction formula for introducing the density term was more suitable for the data of this experiment than the conventional empirical formula for predicting the spray tip penetration.Graphical Abstract
