Method and control device for the control of a turbocharger having a variable geometry turbine

摘要

The method involves generating variable turbocharger pressure for an internal combustion engine (10) using a controllable turbine flow cross-section, and reducing and increasing the cross-section, when an increased pressure is required. A measure for an exhaust gas mass flow is provided by the cross-section, and the increasing of the cross section takes place as a function of the measure for the exhaust gas mass flow. An independent claim is also included for a control device for controlling a turbocharger.
