Abstract:
A system and method are provided for controlling recirculation of exhaust gas to an internal combustion engine having an exhaust gas recirculation (EGR) system comprising an EGR conduit coupled between an exhaust manifold and an intake manifold of the engine. Exhaust gas produced by the engine is trapped within the EGR system in response to detection of a first operating condition that is indicative of a minimum engine fueling rate. The trapped exhaust gas is released from the EGR system into the intake manifold of the engine in response to detection of a second operating condition that is indicative of a subsequent increase in engine fueling rate above the minimum engine fueling rate.
