      Internal combustion engine with exhaust gas fan. The invention relates to an internal combustion engine with an exhaust gas centrifugal fan with an additional electrical drive by an electric motor operated by a generator coupled to the Brünnkraftmaschine and consists of <RTI

   ID = "0001.0018"> in that three-phase current with a frequency of at least 100 Hertz is used for the electrical drive.



  It can also be provided that the additional electrical drive only communicates:

  is then put into operation when the power output of the exhaust gas turbine falls below the power requirement of the rotary blower. The generator for supplying the fan can be excited with a power source located outside the machine group.

   For reversible internal combustion engines, in particular marine propulsion engines, devices can be associated with the reversal, which is mediated by.

   switching over the reversing automatically switches off the excitation temporarily and reverses two phase connections between the electric motor and generator.



  An exemplary embodiment of the subject matter of the invention is shown schematically in the drawing.



  a is a two-stroke diesel engine working in a known manner with an exhaust gas turbine b and a superimposed blower c driven by this, ad, drive machine for the electric generator g. To the at.

       Partial loads of the same from. If the exhaust gas turbine is not able to provide shortfalls in the power requirement of the supercharger in a different way, the supercharger is provided with an additional, electric drive, which consists of a generator driven by the diesel engine itself,

   an electric motor e working on the shaft of the charging blower and the two connecting forks f - consists. This gives the electric motor such a high rotational speed that it can be coupled directly to the supercharger fan, just like the exhaust gas turbine, without requiring a transmission.

   The three-phase system is designed, for example, so that it works at a frequency of 120 Hertz. for the purpose of running a two-pole electric motor at a speed of <B> 7200 </B> revolutions per minute. If the generator is equipped with external excitation, it can be excited with a current duel located outside the machine group. to start the electric motor at the same time as the generator.
