Abstract:
An apparatus for controlling an amount of fuel to be injected into a diesel engine, comprising:first determination means for determining a basic amount of fuel injection from an engine revolution speed and accelerator opening degree;second determination means for determining a maximum amount of fuel injection from the engine revolution speed and an intake air flow rate;third determination means for determining whether a first condition of vehicle speed being zero and a second condition of accelerator opening degree being not zero both hold true;a correction unit for correcting the maximum amount of fuel injection to a smaller value when both the first and second conditions hold true; anda comparison unit for comparing the basic amount of fuel injection with the corrected maximum amount of fuel injection and selecting the smaller one as a target amount of fuel injection when the first and second conditions hold true, and for comparing the basic amount of fuel injection with the uncorrected maximum amount of fuel injection and selecting the smaller one as the target amount of fuel injection when at least one of the first and second conditions holds untrue.
