Abstract
An exhaust gas recirculation control device controls an exhaust gas recirculation device that includes an exhaust gas recirculation passage adapted to circulate a portion of exhaust gas of an internal combustion engine from an exhaust passage downstream of a turbine of a turbo supercharger along an exhaust flow to an intake passage upstream of a compressor of the turbo supercharger along an intake flow and downstream of an air flow meter along the intake flow, and a recirculation control valve adapted to adjust an amount of exhaust gas circulated to the intake passage. Furthermore, the exhaust gas recirculation control device includes recirculation ratio setting means adapted to set a lower target recirculation ratio for a smaller intake air amount of the internal combustion engine.
