EGR control apparatus for diesel engine |
摘要 |
An EGR control apparatus for a diesel engine which can stop EGR in advance of increase of a fuel injection quantity when acceleration of the engine comprises: EGR means (4) to adjust an EGR volume which is recirculated from an exhaust pipe (2) to an intake pipe (3); filter means (7) to carry out a smoothening-process to an accelerator opening degree detected by an accelerator opening degree sensor; injection quantity determination means (7) to determine a target fuel injection quantity to be injected from an injector (20), using the accelerator opening degree after smoothening-processed; and control means (7) to calculate a fuel injection quantity for judging EGR stop (Qcut), using the accelerator opening degree before smoothening-processed, to allow the EGR means (4) to carry out a decrease control for the EGR volume when the fuel injection quantity for judging EGR stop (Qcut) exceeds a predetermined threshold value (Hi). <IMAGE> |
