Abstract
A turbocharger system () of a combustion engine () comprises a turbocharger turbine () operable by exhaust gases, a valve () configured to control gas flow of pressurized gas from a pressurized gas reservoir () to the turbocharger turbine (), and a sensor (). Turbocharger system operation comprises injecting a test pulse of pressurized gas from the pressurized gas reservoir () to drive the turbocharger turbine () by means of controlling the valve (), detecting an impact of injected pressurized gas on the turbocharger turbine () by means of the sensor (), collecting data from the sensor (), and diagnosing the turbocharger system () by evaluating an operational response of the turbocharger turbine () as a result of the injected test pulse of pressurized gas, based on the collected data.
