Patent ID: 8170776

Claim:
A method in order to control an internal combustion engine with self-ignition of the air/fuel mixture and the metering of fuel via a fuel injection valve, the method comprising the steps of: determining at least one injection parameter with respect to the metering of fuel as a function of at least one operating variable of the internal combustion engine under the assumption of a steady-state operating state, in the case of the presence of a transient operating state: determining at least one current operating variable; determining a target combustion chamber temperature corresponding to an assumed steady-state operating state operating according to the determined at least one operating variable, using a predetermined physical model for a transient operation to determine an actual combustion chamber temperature as a function of the target combustion chamber temperature corresponding to the assumed steady-state operating state and at least one of the current operating variables, determining, as a function of both (a) the target combustion chamber temperature corresponding to the assumed steady-state operating state and (b) the actual combustion chamber temperature corresponding to the transient operating state, a correction value for the at least one injection parameter and controlling the fuel injection valve as a function of the at least one injection parameter and the allocated correction value.
