Abstract
A first recirculation system includes a first adjuster to adjust the exhaust-gas flow rate in a first path connecting an upstream position of a turbine of a VG turbocharger to a downstream position of a compressor. A second recirculation system includes a second adjuster to adjust the exhaust-gas flow rate in a second path connecting a downstream position of the turbine to an upstream position of the compressor. A recirculation controller switches between a single use activating the first or second recirculation system and a combination use activating both systems by controlling the adjusters. A pressure controller executes feedback control of an intake-system pressure through adjusting the opening of vanes, and executes feedforward control without the feedback control during a predetermined period from the switching from the single use to the combination use.
