ABSTRACT:
This fuel injection device changes stepwise the effective opening area of the exhaust opening that releases the fuel pressure in the balance chamber, in order to control the lift velocity of the needle valve to give flexibility to the pattern of the initial fuel injection rate. The fuel injection device of this invention switches the current value applied to the solenoid between the large and the small value to change the distance traveled by the solenoid valve and thereby change the opening degree of the exhaust port that releases the fuel pressure in the balance chamber. Because the return spring mechanism having plural springs, the magnitudes of current necessary to be applied to the solenoid to move the solenoid valve are clearly differentiated. This reduces variations in the process of releasing the fuel pressure in the balance chamber, assuring a stable fuel injection rate control. Further, if the amount of current is changed while the needle valve is being lifted, the initial fuel injection rate can be controlled in many ways.
