Determining gas mixture composition in combustion chamber of internal combustion engine with exhaust gas feedback, involves determining state parameters with physically based models

摘要

The method involves determining suitable state parameters of the internal combustion engine using suitable physically based models that simulate the behavior of the internal combustion engine in relation to the state parameters to be determined. The composition and mass of the gas mixture in the combustion chamber are determined using the physically based model. An Independent claim is also included for a control system for an internal combustion engine with exhaust gas feedback.
