Abstract
The invention relates to a method for controlling a turbocharger system () fluidly connected to an exhaust manifold () of a combustion engine (). The turbocharger system comprises a tank () with pressurized gas, and a turbocharger turbine () operable by exhaust gases from the exhaust manifold. The tank is fluidly connectable to the turbocharger turbine. The method comprises the steps of: determining a first operational mode in which zero fuel, or only a predetermined low amount of fuel, is injected to the combustion engine, for a predetermined time period; and, after the predetermined time period, injecting pressurized gas from the tank to drive the turbocharger turbine, such that the turbocharger turbine is activated by the pressurized gas.
