Abstract

An exhaust gas turbocharger for an internal combustion machine, in particular a diesel engine, having an unburnt mixture supply device, includes at least one compressor; at least one exhaust gas turbine; a turbocharger shaft by which the compressor and the exhaust gas turbine are rotationally fixedly coupled; and an energy store for increasing a mass moment of inertia. The energy store is rotationally fixedly coupled to the at least one compressor and the at least one exhaust gas turbine by the turbocharger shaft. An arrangement for supplying unburnt gas to an internal combustion machine includes such an exhaust gas turbocharger and an unburnt gas supply device.
