Correlation analysis of pressure characteristic interaction of electronically controlled injector without static leakage
为揭示无静态泄漏电控喷油器压力波动特性,本文借助AMESim仿真平台,搭建了电控喷油器的数值模型,通过试验数据对比,验证了模型的准确性.定义喷油压力波动与喷油压力降作为压力特性的衡量指标,结合实验设计与相关性分析方法,探究了压力特性与影响参数间交互作用的相关性.结果表明:对于喷油压力波动,进油孔孔径、回油孔孔径、喷孔直径三者间的交互作用具有显著影响,且其相关性受轨压工况的影响显著,在低轨压时,进油孔直径与喷孔直径的交互作用与其成正相关,回油孔孔径…查看全部>>
To reveal the pressure fluctuation characteristics of an electronically controlled injector without static leakage,a numerical model of an electronically controlled injector was established based on the AMEsim hydraulic simulation platform.The accuracy of the model was verified by comparing it with the experimental data.The injec-tion pressure fluctuation and injection pressure drop were defined as the measurement indexes of pressure character-istics.Combine…查看全部>>
