Generator unit, in particular for motor vehicles

A generator unit comprising:

• at least one generator for producing electrical power;
• a first exhaust gas turbocharger provided as a high-pressure exhaust gas turbocharger;
• a second exhaust gas turbocharger provided as a low-pressure exhaust gas turbocharger;
• a compressor unit including at least two compressors connected in series, the at least two compressors including a high-pressure compressor and a low-pressure compressor,
• a flow channel which connects a flow output of the low-pressure compressor to a flow input of the high-pressure compressor,
• a turbine unit including a turbine and a further turbine and operatively connected to the compressor unit, a combustion chamber being situated between the compressor unit and the turbine unit;
• and
• an injection device for injecting fuel into the flow channel between the low-pressure compressor and the high-pressure compressor,
• wherein the second exhaust gas turbocharger includes the low-pressure compressor and the turbine, and wherein an output shaft of the turbine is operatively connected to a drive shaft of the low-pressure compressor,
• wherein the first exhaust gas turbocharger includes the high-pressure compressor and the further turbine, and wherein an output shaft of the further turbine is operatively connected to a drive shaft of the high-pressure compressor,
• wherein the output shaft of the turbine and the drive shaft of the low-pressure compressor are developed separately from the output shaft of the further turbine and from the drive shaft of the high-pressure compressor.
