Abstract
The pressure of the fuel is increased at a constant pressure intensification ratio after operating the pressure reducing device so that the pressure difference between the fuel passage and the control chamber after the operation has a value smaller than the predetermined pressure difference, if the required pressure of the fuel is higher than a reference pressure and lower than a pressure obtained by multiplying the reference pressure by a constant pressure intensification ratio.
