Abstract
An arrangement for controlling fuel injection in a diesel engine to prevent generation of smoke even when an accelerator pedal is stamped during idling. A basic amount of fuel injection Q,is determined from an engine revolution speed Ne and accelerator opening degree Ac. A maximum amount of fuel injection Q,is determined from the engine revolution speed Ne and an intake air flow rate MAF. It is then determined whether a first condition of vehicle speed being zero and a second condition of accelerator opening degree being not zero both hold true. The maximum amount of fuel injection Q,is corrected to a smaller value Q,when both the first and second conditions are met. In this case, the basic amount of fuel injection Qbase is compared with the reduced maximum amount of fuel injection Q,and the smaller one is selected as a target amount of fuel injection Q,.
