の燃焼制御装置。[Scope of Claim for Utility Model Registration] The amount of fuel injection is controlled according to the amount of depression of the accelerator pedal, and in the low rotation range, the ratio of the fuel injection amount to the amount of depression of the accelerator pedal is increased to perform starting supercharging of the fuel, and In a diesel engine that is equipped with an output control means that maintains the rotation speed within a low rotation range where the fuel injection amount ratio to the accelerator pedal depression amount is increased, when the accelerator pedal is depressed from an idle state, the An output operation delay means is provided that delays the response operation of the output control means and prevents the engine from reaching a full load state in a low rotation range where the fuel injection amount ratio to the accelerator pedal depression amount is increased. A diesel engine combustion control device characterized by:
