摘　　要：为研究电控单体泵燃用不同配比生物柴油对喷嘴端压力波动影响,利用GT-Suite软件搭建电控单体泵喷射系统计算模型,验证了模型的准确性.通过研究不同高压油管长度与不同油管直径的结构参数改变对喷嘴端压力的影响,研究结果表明:高压油管直径为2 mm,高压油管长度为500 mm,采用B5生物柴油电控单体泵系统嘴端压力波动较小,稳定性能最佳.该研究可为电控单体泵系统燃用生物柴油对喷嘴端压力波动影响提供参考.The paper studies the effect of using different blending ratio of bio-diesel on nozzle pressure fluctuation of the electronic unit pump system.The GT-Suite software was used to establish the electronic unit pump system model and the accuracy of simulation model was verified by the experiment.The influence of nozzle pressure on different structural parameters of high-pressure line length and diameter were studied.The result showed that when high-pressure line diameter was2mm&length was500mm,using B5bio-diesel could get a smaller and stable nozzle pressure fluctuation on electronic unit pump system.The research offers references for the study of the effect of the use of bio-diesel on nozzle pressure fluctuation of electronic unit pump system.
