ABSTRACT:
An electromagnetic controlled fuel injection apparatus is provided in which a housing assembly with two sets each including a solenoid device and an open/close valve device being fixed directly to a housing is fixed to a plunger unit to decrease the length of the fuel passages between the open/close valve devices and a plunger room in order to increase the speed of injection response in two-stage fuel injection for reducing NOx emission while maintaining engine performance and to facilitate mounting of the apparatus on constricted space of an engine.
