Abstract (en)
[origin: WO03046356A2] The invention relates to an engine management system wherein physically based models (16-21) are used to determine the composition and mass of the fresh air/ exhaust gas mixture suctioned by an internal combustion engine (1). Said models respectively simulate the behavior of the internal combustion engine or corresponding engine system in relation to specific state variables. The individual physically based models (16-21) are closely coupled to each other in a partial manner and are used, for instance, to simulate the filling of the combustion chamber of the internal combustion engine(1) with the suctioned fresh air/waste gas mixture in order to simulate the flow of the mass of re-circulating exhaust gas, in order to simulate the behavior of the exhaust gas manifold of the internal combustion engine (1) upstream and downstream from a turbine (2), in order to simulate the storage behavior of the intake manifold of the internal combustion engine, and to simulate the behavior of the intake pipe or inlet manifold whereby the fresh air/exhaust gas mixture is fed to the combustion engine (1) from a corresponding mixing point (10) where the suctioned fresh air is mixed with the exhaust gas re-circulated via the exhaust gas re-circulation line. As a result, a plurality of additional state variables can be determined without additional sensors.
