Method and control unit for controlling a variable turbo charger turbine flow cross section

摘要

The method involves changing a load of a petrol engine (10) from a small load value to a large load value. An actuator (42) is controlled in a delayed manner for adjusting a turbine flow cross section which is adjusted for the large load value in relation to exchange of the load. A measure of the delay is pre-determined independent of an operating parameter of the petrol engine, where the operating parameter is torque of the petrol engine, during exchange of the load. An independent claim is also included for a control device for controlling an actuator for adjusting the turbine flow cross section of the turbo charger of the petrol engine in a motor vehicle.
