Controlling an internal combustion engine with EGR based on a combustion model

摘要

An internal combustion engine (1) has a throttle flap (9) via which the air is supplied to an intake manifold (7). An exhaust-gas recirculation (13, 14) is provided via which the exhaust gas is recirculated from an exhaust-gas pipe (8) to the intake manifold (7). A control apparatus is provided for open-loop and/or closed-loop controlling the engine. With the control apparatus, the gas mixture in the intake manifold (7) can be subdivided into a fresh gas component (rffgabg), an inert gas component (rffigabg) and a fuel gas component (rfhcabg).
