ABSTRACT:
In a method and apparatus for controlling a supercharged internal combustion engine including an exhaust gas turbocharger having variable turbine inlet vanes, an engine control unit includes an engine performance graph with control parameters for a multitude of engine operating points compressor performance graph is also recorded in the engine performance which represents for various exhaust gas turbocharger speeds a particular relationship between mass flow through the compressor and total pressure ratio. A multitude of engine operating curves for constant turbine guide vane positions and constant engine speeds for various engine loads and engine operating modes are also recorded and retrieved by the engine control unit for controlling the engine depending on desired engine load and engine speed for adjusting the turbine inlet vanes.
