Abstract

The invention relates to an internal combustion machine (10), comprising a combustion engine (1) having an exhaust gas side (AGS) and a charging fluid side (LLS), and having a supercharger system (14) comprising an exhaust gas turbo charger (40) for charging the combustion engine (1), having a condenser array (41) on the charging fluid side (LLS) and a turbine arrangement (42) on the exhaust gas side (AGS), a compressor (3), the primary side (I) of which is connected to the charging fluid side (LLS), and the secondary side (II) of which is connected to the exhaust gas side (AGS). An electric machine (4) configured as a motor/generator is coupled to the combustion engine (1), wherein the electric machine (4) as a generator can be powered by the combustion engine (1), or can power the combustion engine (1) as a motor, wherein the compressor (3) can be powered directly by the electric machine (4) via a mechanical drive coupling (13).
