PURPOSE:To improve responsiveness of an apparatus for controlling the injection quantity of fuel in a diesel engine, by detecting a prediction value of the next engine-speed information from past engine-speed information, and detecting the injection quantity of fuel from said predicton value. CONSTITUTION:The discharge port side and the suction port side of a plunger pump (A) of a diesel engine are communicated with each other via a solenoid valve (B). The solenoid valve (B) is controlled by a solenoid valve driving means (F) according to the injection quantity of fuel detected by an arithmetic means (E), to which output signals of a means (C) for detecting the reference rotational position and a means (D) for detecting various operational conditions are furnished. The arithmetic means (E) calculates a prediction value by use of past engine-speed information detected by use of the means (C) for detecting the reference rotational position and calculates the injecton quantity of fuel by use of said prediction value and the output signal of the means (D) for detecting various operational conditions of the engine. With such an arrangement, it is enabled to improve transient responsiveness of an injection quantity controlling apparatus.
