Abstract

An internal combustion engine is described. The internal combustion engine comprises a valve control which is configured to close inlet valves of the internal combustion engine at Miller or Atkinson closing times. An electrified exhaust-gas turbocharger of the internal combustion engine comprises an electric machine which is operable selectively as a motor or generator. A control unit operates the electric machine of the electrified exhaust-gas turbocharger as a motor in a first load range of the internal combustion engine and as a generator in a second load range which corresponds to greater loads of the internal combustion engine than the first load range.
