System for operating an internal combustion engine

摘要

An internal combustion engine, in particular for a motor vehicle, includes a throttle arranged in an intake pipe, through which air can be fed to a combustion chamber. Furthermore, the internal combustion engine includes a valve arranged in an exhaust gas recirculation line, through which exhaust gas can be fed to the intake pipe. A first mass flow through the throttle can be determined by a control device. Furthermore, a second mass flow through the valve can be determined by the control device. Finally, a third mass flow fed to the combustion chamber can be determined by the control device from the first mass flow through the throttle and the second mass flow through the valve.
