摘要
介绍了一种新的柴油机高压共轨喷油系统高速电磁铁铁芯 ,新铁芯由许多厚度相等的涡旋形铁片堆叠而成。构成铁芯的方法之一是采用渐开线直纹面作为涡旋形铁片的理论曲面。铁片与铁片之间无间隙 ,电磁铁线圈安放在铁芯的沟槽内。它比常见的E形叠片电磁铁铁芯结构紧凑 ,性能更好。试验结果表明 ,新的电磁铁铁芯能满足ECD
In this paper a new high speed solenoid stator for high pressure common rail fuel injection system is introduced.The stator is constructed by stacking a number of scroll-shaped magnetic plates with a uniform plate thickness. One of methods to construct the stator is taking involute ruled surface as theoretical surface of the scroll-shaped plates .There is no air gap between iron plates .The coil is put in the grooves of the plates.It is more compact and effective than the usual E- shaped solenoid stator. Test results show that the new solenoid stator can satisfy the demands of ECD-U2 high pressure common rail fuel injection system.
