    摘要： A system for automatic charging pressure control using an exhaust gas turbocharger with a variably adjustable turbine cross-section and for automatic exhaust gas recirculation control in the case of an internal-combustion engine, particularly a diesel engine. An automatic control system has a first controller which has an output for the variation of the turbine cross-section of the exhaust gas turbocharger. The command variable for the automatic exhaust gas recirculation control in a first low load-rotational speed range is the air flow rate in the intake pipe. The command variable for the automatic charging pressure control in a second higher load-rotational speed range is the charging pressure in the intake pipe. For the automatic exhaust gas recirculation control, an exhaust gas recirculation pipe connects the exhaust gas pipe with the suction pipe. In the case of this system, for achieving the lowest possible pollutant emission while simultaneously minimizing fuel consumption, exhaust gas recirculation rates which are as precise as possible are defined in the lower load-rotational speed range, and a charging pressure which is as precise as possible is defined in the upper load-rotational speed range via a corresponding automatic control.
