摘要：
The invention relates to a method for controlling a turbocharger system (10) fluidly connected to an exhaust manifold (102) of a combustion engine (100) and an exhaust after treatment system (900). The turbocharger system (10) comprises a turbocharger turbine (22) operable by exhaust gases from the exhaust manifold, and a tank (40) with pressurized gas, the tank being fluidly connectable to the turbocharger turbine. The method comprises the steps of: determining a NOx parameter being indicative of, or correlated to, NOx emissions from the exhaust after treatment system; and injecting pressurized gas from the tank to drive the turbocharger turbine based on the determined NOx parameter, wherein a determined NOx parameter above a pre-defined first threshold determines that pressurized gas from the tank is injected.
