ABSTRACT:
A method of estimating the airflow into a compression ignition engine having an exhaust gas recirculation system (EGR) and a variable geometry turbocharger (VGT). The method includes the steps of generating an EGR flow value as a function of the intake manifold pressure (MAP), exhaust manifold pressure (EXMP), position of the exhaust gas recirculation valve, and temperature of the gas flowing through the EGR. From this calculation, the method generates an intake airflow value (MAF) as a function of the EGR flow value and the intake aircharge temperature. The intake airflow value is used, in turn, to control the position of the EGR valve. The disclosed method thereby eliminates the necessity for a MAF sensor.
