Abstract

In order to obtain improved performance, the control unit controlling an engine provided with Variable Turbine Geometry (VTG) is adapted to predict (203) a future need for a high torque. In response to determining that there will be a demand for a high torque in the near future, the control unit controlling (205) the engine increases charge gas pressure by closing the VTG to a more closed position for the same engine speed, thereby enabling a higher power to be generated by the turbine of the VTG so that when a demand for a higher torque is signaled to the control unit, the compressor of the turbo charger can generate a high turbo pressure instantly and thereby improve the response to the increased demand for torque.
