Cylinder air charge estimation system and method for internal combustion engine including exhaust gas recirculation |
摘要 |
A system (12) and method for determining the charged air mass in a cylinder (14) of an internal combustion engine (10) are provided. The system (12) includes an electronic control unit (ECU) (58) configured to determine a temperature of the combination of charged air and recirculated exhaust gas inducted into the cylinder (14). The ECU (58) is further configured to determine a total mass flow rate of the combination of inducted air and recirculated exhaust gas based on a pressure in an intake manifold (22) of the engine (10) and the previously determined temperature. Finally, the ECU (58) is configured to determine the mass of charged air in the cylinder (14) from the total mass flow rate.
