Abstract

PURPOSE: To enable a control operation over a pressure for opening valve under an injection and a condition of injection in response to an operating condition of the engine by a method wherein there is provided a hydraulic actuator cooperatively arranged in a direction of the nozzle spring and for controlling a pressure of the nozzle needle for opening the valve.
CONSTITUTION: Hydraulic pressure is applied to a hydraulic chamber 9 of a hydraulic actuator 12, a combined force of force of hydraulic pressure acted upon the piston 10 and a force of a spring 6 is applied to the nozzle needle 3. The hydraulic pressure is controlled by a high speed solenoid valve and its pressure is varied. Therefore, no injection is made unless a high pressure for opening the valve overcoming the combined force for the valve opening operation is produced, and the pressure for opening the valve may be varied by controlling a hydraulic pressure in response to an operative condition. Condition of injection can be controlled in such a manner as the pressure is increased smoothly at the intial starting time of opening the valve and rapidly decreased at the end of the valve opening time, and thus it is possible to prevent a deterioration of fuel consumption, a fiesel knocking and a production of smoke.
