摘　　要：文章通过总结前人研究成果,阐述了生物柴油喷雾特性研究进展,探索生物柴油喷雾特性进一步研究的方向。研究发现生物柴油的贯穿距离和索特平均直径比柴油大,喷雾锥角比柴油小,并且粘度对其雾化质量的影响最大;添加醇类和醚类可以明显改善生物柴油的雾化特性。指出开展生物柴油喷嘴内流动的仿真和试验研究具有重要意义。The purpose of this paper was to understand the research progress and explore the new research direction aboutbiodiesel spray characteristics through summarizing predecessors'research results.Available literatures show that the spraytip penetration(STP)and Sauter mean diameter(SMD)of biodiesel are larger than those of diesel,the cone angle of biodieselis smaller than that of diesel,viscosity of the biodiesel has the most effect on atomization quality.Adding alcohols and ethersin biodiesel can greatly improve its atomization characteristics.Finally,this paper propose that it is important significance todevelop simulation and experimental research on the biodiesel flow in the nozzle.
