Method and control unit for setting a turbine flow cross-section

摘要

A turbine flow cross-section of a turbocharger of an internal combustion engine, is set such that a lower limit (TSQ_dyn_min) of a range of settable values of the turbine flow cross-section is determined as a function of an operating parameter of the internal combustion engine in non-stationary operating states. A speed of the internal combustion engine can be used as the operating parameter.
