| description | A method for operating an internal combustion engine, wherein at least a first map (10) of prefixed first values is predetermined, each prefixed first value being a function of a prefixed nominal fuel quantity (Q ecu_prefix ). According to the invention the method comprises the steps of determining a nominal fuel quantity (Q ecu ) for one injection, calculating an actual, torque forming, injected fuel quantity of the injection (Q UEGO ) and calculating at least one first parameter (Q delta ) which is related to the actual, torque forming, injected fuel quantity of the injection (Q UEGO ). After that, the nominal fuel quantity (Q ecu ) is modified according to the value of the at least one first parameter (Q delta ) so as to obtain a corrected fuel quantity (Q ecuCorr ) that corresponds to the actual fuel quantity injected during the injection. The method further comprises the step of comparing the corrected fuel quantity (Q ecuCorr ) with each of the prefixed nominal fuel quantity (Q ecu_prefix ) and operating the engine using, from the first map (10), the first values which corresponds to the corrected fuel quantity (Q ecuCorr ), according to the result of said comparison. |
