| 摘 要： | 采用Hydsim软件建立电控单体泵系统仿真模型,并通过试验数据进行模型标定。采用该模型仿真分析了电控单体泵系统关键结构参数对其性能的影响。仿真结果表明:喷孔总流通面积与最大喷射压力成反比,与最大喷油速率成正比;高压油管长度对喷射压力和喷油速率影响很小,仅影响喷油提前角;高压油管直径对最大喷油速率影响很小,与最大喷射压力成反比。

| Abstract: | The simulation model of electronically controlled unit pump(EUP)system was built up using Hydsim software, and the model was calibrated with experimental data. The influence of key structure parameters of EUP system on its performance was studied using this simulation model. The simulation results show that the injection nozzle''s total flow area is in inverse proportion to maximum injection pressure, and in direct proportion to maximum injection rate; the length of high-pressure fuel pipe has little influence on the injection pressure and injection rate, but only influence the injection advance angle; the diameter of high-pressure fuel pipe has little influence on maximum injection rate, and is in inverse proportion to maximum injection pressure. |
