Abstract
The correct estimation of the air charge is crucial for the control of gasoline engines. This paper introduces an air charge estimation based on both physical and statistical models. For the physical model, an investigation was made to determine if the assumption of an isothermal process in the intake manifold is too strict and should be weakened to an assumption of an adiabatic process. For the adaptation of the statistical models, the Design of Experiments (DoE) method is used. The DoE method can shorten test expenses and calibration time significantly. The resulting model was tested with a 2-liter gasoline engine.
