Title: METHOD AND DEVICE FOR OPERATING AN INTERNAL COMBUSTION ENGINE WITH SUPERCHARGING AND EXHAUST-GAS RECIRCULATION
Abstract:
The invention relates to a method for operating an internal combustion engine, in particular a diesel internal combustion engine, having supercharging (300) with exhaust-gas recirculation, an engine with a number of cylinders, and supercharging control with an outer master controller (111, 112) and a cascaded inner secondary controller (113, MIMO), the control variables (191, 192, 193, 194) of which are based at least on a charge-air variable and an exhaust-gas variable of the supercharging, wherein the supercharging is assigned a first manipulated variable (195) which sets the charge air and a second manipulated variable (196) which sets the exhaust gas, by means of the supercharging control.
