Abstract

The turbine of the exhaust gas turbocharger, which is located in the exhaust gas channel of the internal combustion engine, has a variable geometry. The regulation of the boost pressure is performed via an adjustment of the turbine geometry. A very rapid response of the boost pressure regulation to a variable load, with an overshoot of the specified value, which would damage the turbocharger, being avoided, is achieved by determining a manipulated variable for the turbine geometry as a function of the exhaust gas back pressure prevailing in the exhaust gas channel upstream from the turbine.
