Methods and systems for a comprex charger

A charged internal combustion engine, comprising:

• at least one cylinder;
• an exhaust gas discharge system configured to discharge exhaust gases;
• an intake system configured to supply charge aft to the at least one cylinder;
• and
• at least one comprex charger comprising a cylindrical cellular wheel which is rotatable about a rotation axis, is arranged in a housing, and comprises a plurality of cells which extend between end faces of the cellular wheel along the rotation axis of the cellular wheel, wherein the comprex charger comprises a liquid cooling system, wherein the comprex charger is electrically driven via an electrical machine, wherein the electrical machine comprises a stator and a rotor, wherein the comprex charger and the electrical machine are configured as an integrated component, wherein the cellular wheel is configured as the rotor, and wherein the housing is configured as the stator.

A system, comprising:

• an engine comprising an exhaust gas discharge system and an intake system;
• and
• a comprex charger comprising a cylindrical cellular wheel rotatable about an axis of rotation within a housing, wherein the cylindrical cellular wheel comprises a plurality of cells extending from a first extreme end to a second extreme end, opposite the first extreme end of the cylindrical cellular wheel;
• wherein
• the comprex charger is electrically driven via an electric machine, the comprex charger and the electric machine are configured as an integrated component, wherein the housing is configured as a stator of the electric machine and the cellular wheel is configured as a rotor of the electric machine, further comprising a cooling arrangement completely encasing the cellular wheel.
