摘要： A system controlling an air handling system for an internal combustion engine. An EGR valve in-line with an EGR passageway fluidly coupled between exhaust and intake manifolds of the engine is controllable between fully closed open positions to control a flow rate of exhaust gas through the EGR passageway. A control circuit determines a pump enable value as a function of at least one of a target engine speed and a total fueling target, determines a maximum achievable flow rate of recirculated exhaust gas through the EGR passageway with the EGR valve in the fully open position, and activates an electric gas pump to increase the flow rate of exhaust gas through the EGR passageway if the pump enable value exceeds a threshold pump enable value and a target flow rate of recirculated exhaust gas through the EGR passageway is less than the maximum achievable flow rate.
