【摘要】：為揭示不同電磁場參數(shù)對GDI噴油器動態(tài)響應特性的影響機理,建立了某款GDI多孔噴油器電磁閥的數(shù)學模型和Maxwell三維瞬態(tài)電磁場仿真模型,并進行仿真。結(jié)果表明:適當減小電磁線圈匝數(shù)、保持電壓、工作氣隙和滑動氣隙,增大開啟電壓可有效改善噴油器的動態(tài)響應特性。另外,為降低鐵芯的渦流損耗,結(jié)合參數(shù)匹配對GDI噴油器及其磁路進行了綜合改進,使GDI噴油器的動態(tài)響應特性明顯提高。
[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.
