ABSTRACT:
An engine control device is configured to prevent surging in an engine equipped with both a variable-nozzle turbocharger and an EGR device while curbing costs by utilizing existing equipment and avoiding undesirable secondary effects. When the engine is in a prescribed engine operating state in which the fuel injection quantity should be reduced, the EGR quantity delivered by the EGR device is reduced to a value lower than the normal value and the opening degree of the turbine nozzle of the turbocharger is increased. The prescribed engine operating state is defined to exist when the vehicle is decelerating and when the fuel injection quantity is decreased after regeneration of the NOx trapping catalytic converter.
