    Abstract: Systems, methods, and apparatus include determining an exhaust gas recirculation (EGR) flow rate. An effective flow area of an EGR system is determined based on a position of an EGR control valve of the EGR system and a pressure differential between an exhaust manifold pressure (EMP) and an intake manifold pressure (IMP) of an internal combustion engine. In response to the effective flow area, the pressure differential between the EMP and the IMP, the EMP, the IMP, and an exhaust manifold temperature the EGR flow rate is determined and a fraction of EGR flow in the charge flow is adjusted in response to the EGR flow rate.
