【摘要】：为揭示不同电磁场参数对GDI喷油器动态响应特性的影响机理,建立了某款GDI多孔喷油器电磁阀的数学模型和Maxwell三维瞬态电磁场仿真模型,并进行仿真。结果表明:适当减小电磁线圈匝数、保持电压、工作气隙和滑动气隙,增大开启电压可有效改善喷油器的动态响应特性。另外,为降低铁芯的涡流损耗,结合参数匹配对GDI喷油器及其磁路进行了综合改进,使GDI喷油器的动态响应特性明显提高。
[Abstract]:In order to reveal the influence mechanism of different electromagnetic field parameters on the dynamic response characteristics of GDI injector, a mathematical model of a GDI injector solenoid valve and a Maxwell three-dimensional transient electromagnetic field simulation model are established and simulated. The results show that the dynamic response characteristics of the injector can be improved by decreasing the turn number of electromagnetic coil holding voltage working air gap and sliding air gap and increasing the opening voltage. In addition, in order to reduce the eddy current loss of the core, the GDI injector and its magnetic circuit are comprehensively improved in combination with parameter matching, and the dynamic response characteristics of the GDI injector are improved obviously.
