ABSTRACT:
In a method of controlling the charge air mass flow of an internal combustion engine having an exhaust gas turbocharger with adjustable turbine inlet guide vanes during dynamic operation of the engine from one stationary operating state with a given engine power output to another stationary engine operating state with a greater engine power output, the flow guide vanes are first moved to a closing position providing a minimum flow cross-section and, after a certain engine operating parameter reaches a certain control value, the guide vanes are opened at a rate depending on the charge air pressure in the intake duct of the engine to a final opening position corresponding to the other stationary engine operating state.
