Method for determining an air volume in a combustion chamber of an internal combustion engine

A method for determining an air volume in a combustion chamber of a fuel-injection internal combustion engine, especially during a load change condition, including synchronizing a throttle valve setpoint signal to an operating state criterion (tn); determining a curve dynamics of the throttle valve...

Beschreibung
Zusammenfassung:	A method for determining an air volume in a combustion chamber of a fuel-injection internal combustion engine, especially during a load change condition, including synchronizing a throttle valve setpoint signal to an operating state criterion (tn); determining a curve dynamics of the throttle valve position taking into account the synchronized throttle valve setpoint signal; determining an actual air volume quantity at an ACTUAL time point (t0); determining a desired time point (t0+Δt); predicting a further air volume quantity for the desired time point (t0+Δt) and determining a total air volume quantity from the ACTUAL air volume quantity and the further air volume quantity for the desired time point (t0+Δt).
