<p>The method involves adjusting a pressure drop ratio of a turbocharger (60) around a pressure drop ratio set point (111). Maximum value for the set point is determined such that at the time of a transitional stage, the adjusted pressure drop ratio is less than the maximum value, where the value depends on a parameter e.g. turbocharger power output, characterizing the operation of the turbocharger. An independent claim is also included for an internal combustion engine controlling system comprising a turbocharger.</p> |
