Abstract
Engine cylinder inlet air rate measurement is provided with minimization of system calibration and parameter measurement using a correction generated under steady state engine inlet air dynamic conditions through a comparison of mass airflow-based engine inlet air rate measurement and a nominal calculated cylinder inlet air rate. The correction may be periodically updated under steady state engine inlet air dynamic conditions and may be applied under all engine inlet air dynamic conditions, especially transient inlet air dynamic conditions.
