Abstract
PURPOSE: To enable the most preferable control over a characteristic of injection in response to an operating condition of the internal combustion engine by a method wherein a fuel injection valve provided with a hydraulic actuator is utilized.
CONSTITUTION: Pressure chamber 3 is formed in a fuel injection valve B, and a pushing-up force acting upon the piston 34 is acted upon a nozzle needle 31 as a valve closing force as a pressure in the pressure chamber 33 is varied. One of a plurality of injection valves B is assembled with a nozzle lift sensor 38 for sensing a movement of the nozzle needle 31 through a spring 32. To the control circuit 45 are applied an angle pulse from a crank angle sensor, an injection starting signal from the nozzle lift sensor 38 and an injection terminal signal so as to control a correction adjustor 46 by a feed-back operation and at the same time a pressure in a pressure chamber 33 is varied even in case of one injection process and thus a characteristic of injection may be controlled.
