Abstract

An internal combustion engine, including at least one electric motor ( 8, 13, 16, 20 ) situated on the crankcase of the internal combustion engine, at least one control unit ( 1 ) for controlling the internal combustion engine and/or the electric motor and at least one high voltage converter ( 15 ).

First claim

What is claimed is:

1. An internal combustion engine comprising:
a crankcase;
a first electric motor situated on the crankcase;
at least one control unit for controlling at least one of the internal combustion engine and the electric motor; and
at least one high voltage converter mounted on top of a front plate, the front plate being connected to a front face of the crankcase, the first electric motor being attached to the front plate by an adaptor unit fixed to the front plate.

2. The internal combustion engine as recited in claim 1 wherein the first electric motor is configured as a generator.

3. The internal combustion engine as recited in claim 1 further comprising a cylinder head cover and a common rail situated in the cylinder head cover.

4. The internal combustion engine as recited in claim 1 further comprising a cylinder head cover and a cable harness is situated in the cylinder head cover.

5. The internal combustion engine as recited in claim 4 wherein the control unit is configured for connecting to the cable harness.

6. The internal combustion engine as recited in claim 1 further comprising a cylinder head cover, the control unit being situated on or at the cylinder head cover.

7. The internal combustion engine as recited in claim 1 further comprising a second electric motor on an exhaust gas side of the crankcase.

8. The internal combustion engine as recited in claim 7 further comprising a third electric motor on a service side of the crankcase, the service side being opposite of the exhaust gas side.

9. The internal combustion engine as recited in claim 8 further comprising a fourth electric motor on the exhaust gas side of the crankcase.

10. The internal combustion engine as recited in claim 1 wherein the high voltage converter is connected to the first electric motor by cables, the electric motor being below the high voltage converter.

11. An internal combustion engine comprising:
a crankcase;
a first electric motor situated on a front face of the crankcase, the first electric motor being configured as a generator;
a second electric motor situated on an exhaust gas side of the crankcase, the second electric motor being configured as a starter;
at least one control unit for controlling at least one of the internal combustion engine and the electric motor;
at least one high voltage converter; and
an exhaust gas turbocharger positioned above the second electric motor on the exhaust gas side of the crankcase.

12. The internal combustion engine as recited in claim 11 further comprising an engine oil cooler situated on the exhaust gas side of the crankcase approximately at a height of and spatially behind the second electric motor.

13. The internal combustion engine as recited in claim 12 further comprising an exhaust gas recirculation module situated on the exhaust gas side of the crankcase above the engine oil cooler.

14. The internal combustion engine as recited in claim 11 further comprising a cylinder head and a high-pressure pump situated on a side of the cylinder head.

15. The internal combustion engine as recited in claim 11 wherein the high-pressure pump situated on a service side of the cylinder head, the service side being opposite the exhaust gas side on the internal combustion engine.

16. The internal combustion engine as recited in claim 15 further comprising a cylinder head cover and a common rail situated in the cylinder head cover, the high-pressure pump being configured for connecting without cables to the common rail.

17. An internal combustion engine comprising:
a crankcase;
an electric motor mounted by a supporting bracket on a service side of the crankcase;
at least one control unit for controlling at least one of the internal combustion engine and the electric motor;
at least one high voltage converter;
a hydraulic pump situated below the electric motor on the service side of the crankcase, the supporting bracket abutting the hydraulic pump.

18. The internal combustion engine as recited in claim 17 further comprising an adaptive transmission, the hydraulic pump and the electric motor being situated on the adaptive transmission.

19. The internal combustion engine as recited in claim 17 further comprising a diesel high-pressure pump for suppling fuel to fuel injectors and a power takeoff situated below the diesel high-pressure pump on the service side of the crankcase.

20. The internal combustion engine as recited in claim 19 further comprising an adapter transmission situated below the power takeoff on the service side of the crankcase.
