Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS

1. An internal combustion engine comprising:

- at least one piston-cylinder unit (2),

- a turbocharger (4) having a shaft (9) driven by an exhaust gas turbine (3), and

- a catalytic converter (5) connected between the at least one piston-cylinder unit (2) and the exhaust gas turbine (3),

characterised in that there is provided an electrical machine (8) connected to the shaft (9).

2. An internal combustion engine as set forth in claim 1 characterised in that there is provided a compressor (7) of the turbocharger (4), that is driven by the shaft (9).

3. An internal combustion engine as set forth in claim 1 or claim 2 characterised in that there is provided a mixing device (13) for adding a fuel (F) to an exhaust gas flow upstream of the catalytic converter (5).

4. An internal combustion engine as set forth in one of claims 1 through 3 characterised in that there is provided an open-loop or closed-loop control device (18) connected to the electrical machine (8).

5. An internal combustion engine as set forth in claim 4 characterised in that there is provided a mixing device (13) connected to the open-loop or closed-loop control device (18) for producing a fuel-air mixture and that the open- loop or closed- loop control device (18) is adapted to activate the mixing device (13) and the electrical machine (8) as a drive while the at least one piston-cylinder unit (2) is in a condition in which no combustion takes place.

6. An internal combustion engine as set forth in claim 5 characterised in that the mixing device (13) is arranged in flow relationship between the at least one piston-cylinder unit (2) and the catalytic converter (5).

7. An internal combustion engine as set forth in claim 5 or claim 6 characterised in that there is provided a by-pass conduit (14) for by-passing the at least one piston-cylinder unit (2), that is connected in flow relationship to a feed conduit (15) for air or fuel-air mixture to the at least one piston-cylinder unit (2) and a connecting conduit (16) between the at least one piston-cylinder unit (2) and the catalytic converter (5).

8. An internal combustion engine as set forth in claim 7 characterised in that a shut-off valve (17) is provided in the by-pass conduit (14).
