时间控制式电控VE分配泵系统的开发

时间控制式电控VE分配系在机械式VE分配泵的基础上，通过对机械液压系统的简化和改进，引入电控单元及电磁控制阀执行器等系统，采用电子控制油量和机电混合控制正时的控制方案，电磁问提供数字控制使得每次喷射都可精确控制，优化油泵的性能，达到了降低轻型车柴油机的排放、提高燃油经济性、改善驾驶舒适性的目的。

A mechanical type VE distribution pump is modified and simplined into a time control type electronically controled VE distribution pump. Electronical control unit and electro-magnetic control valve executor system are introduced to form a control scheme to control fuel amount electronically and control time with hybird electromechanical control. Accuratecontrol for every injection may be obtained with digital control provided by the electro-magnetic valve which optindzes the fuel pump charateristics to make the light duty truck Diesel engine exhaust endssion lowered, fuel economy raised and comfort of driving improved.
