A method is described of controlling a fuel injection quantity into cylinders of a diesel engine combined with a fuel injection pump having a solenoid-operated spill valve, comprising the steps of: (a) sensing engine operating conditions including an engine rotational speed and an operating amount of an accelerating pedal of the engine; (b) calculating a desired fuel injection quantity into the cylinders of the engine in accordance with the sensed engine operating conditions; (c) deriving a desired spill phase angle of rotation of the pump drive shaft as a function of the calculated fuel injection quantity; (d) producing a reference rotational angle signal at a reference angle of rotation of a drive shaft of the fuel injection pump; (e) producing a rotational angle signal for each predetermined angle of rotation of the drive shaft of the fuel injection pump; (f) obtaining a quotient and a remainder angle by dividing the derived spill phase angle by the predetermined angle; and (g) converting the obtained remainder angle into a first converted time on the basis of the sensed engine rotational speed.
