Abstract:
1. An EGR control apparatus for a diesel engine comprising: EGR means to adjust an EGR volume which is recirculated from an exhaust pipe to an intake pipe; filter means to carry out a smoothening-process to an accelerator opening degree detected by an accelerator opening degree sensor; injection quantity determination means to determine a target fuel injection quantity to be injected from an injector, using the accelerator opening degree after smoothening-processed; and control means to calculate a fuel injection quantity for judging EGR stop, using the accelerator opening degree before smoothening-processed, to allow the EGR means to carry out a decrease control for the EGR volume when the fuel injection quantity for judging EGR stop exceeds a predetermined threshold value.
