Abstract
A method and a device for operating an internal combustion engine make it possible to set a setpoint value for the overall fresh air mass flow as the top control target. The internal combustion engine has a multi-flow air system including a multi-channel air supply and a corresponding multi-channel exhaust gas discharge, exhaust gas being recirculated from the multi-channel exhaust gas discharge into the multi-channel air supply and the exhaust gas recirculation being regulated for setting a setpoint fresh air mass flow. A value for the required overall fresh air mass flow of the internal combustion engine is predefined for at least one exhaust gas recirculation channel as the setpoint for the exhaust gas regulation.
