Abstract:
When an EGR control valve is fixed and a valve opening degree EGRVO of the EGR control valve is greater than a valve-opening threshold value EGRVOth, a limit value Qlim of the intake air amount is set to a prescribed amount Qlim1. Conversely when the EGR control valve is fixed and the valve opening degree EGRVO of the EGR control valve is less than or equal to the valve-opening threshold value EGRVOth, the limit value Qlim of the intake air amount is set to a prescribed amount Qlim2.
