PURPOSE:To prevent the lowering of output under low rotation zone and to eliminate production of black smoke under high rotation zone by correcting the fuel supply quantity based upon a fuel supply correction quantity being set continuously according to the increase/decrease of the rotary speed of a Diesel engine. CONSTITUTION:The fuel supply quantity of a fuel injection pump is regulated (P3) to a demand fuel quantity (P1) corresponding to the pressure of the environment where a Diesel engine exists. The fuel supply quantity is corrected (P2) based upon a supply correction quantity being set continuously corresponding to the increase/decrease of the rotary speed of Diesel engine. Consequently, excessive compensation does not occur under low rotary speed region thereby insufficient power can be eliminated. Under high rotary speed region, insufficient compensation does not occur thereby production of black smoke can be eliminated.
