摘要： A system according to the principles of the present disclosure includes a volumetric efficiency adjustment module and an exhaust gas recirculation (EGR) flow adjustment module. The volumetric efficiency adjustment module adjusts an estimated volumetric efficiency of an engine based on a mass flow rate of air entering the engine. The EGR flow adjustment module selectively adjusts an estimated mass flow rate of exhaust gas passing through an EGR valve based on an amount by which the volumetric efficiency adjustment module adjusts the volumetric efficiency.

摘要： An engine control system for a vehicle includes a flowrate module, first and second mass fraction calculating modules, and an actuator control module. The flowrate module determines a mass flowrate of exhaust gas recirculation (EGR) to an engine. The first mass fraction calculating module, based on the mass flowrate of EGR, determines a first mass fraction of recirculated exhaust gas relative of a first gas charge for a first combustion event of the engine. The second mass fraction calculating module determines a second mass fraction of recirculated exhaust gas of a second gas charge for a second combustion event of the engine based on an average of the first mass fraction and one or more other values of the first mass fraction determined for other combustion events, respectively. The actuator control module selectively adjusts an engine operating parameter based on the second mass fraction.
