装置。[Scope of Claim for Utility Model Registration] A fuel injection amount control device for a turbocharged diesel engine equipped with a boost compensator that suppresses the maximum injection amount to a predetermined amount when the intake pressure is below a predetermined positive pressure, which A detecting means for detecting a sudden acceleration state using negative pressure; and a correcting means for correcting to further reduce the maximum injection amount from the predetermined amount in a predetermined rotation range above the idle rotation speed only when the detecting means detects the no-load sudden acceleration. Fuel injection amount control device for diesel engine with supercharger.
