Abstract
A method for setting an exhaust gas recirculation rate in an engine system having an internal combustion engine, the exhaust gas recirculation rate indicating the portion of the exhaust gas recirculated into one cylinder of the internal combustion engine with regard to the total gas quantity present in the cylinder, including: operating the internal combustion engine according to an input for the exhaust gas recirculation rate, an ignition of an air/fuel mixture being carried out in the cylinder at a certain ignition timing; adjusting the ignition timing in the cylinder of the internal combustion engine; correcting the input for the exhaust gas recirculation rate as a function of a change in an operating behavior of the internal combustion engine due to the ignition timing adjustment.
