Claims
- 1. A charged internal combustion engine (1) including:
(a) at least one stage of charging by a turbocharger (3); (b) at least one supplemental compressor (4) connected to the turbocharger; (c) a heat exchanger (13) arranged downstream of the turbocharger; (d) an electric motor (5) drive for the supplemental compressor (4) ; and (e) at least one closing or switching means (11) provided between the supplemental compressor (4) and the turbocharger, wherein the internal combustion engine (1) includes a control means for the control of the supplemental compressor.
- 2. The charged internal combustion engine (1) of claim 1, wherein an electronic control device (40) is present to regulate operation of the supplemental compressor (4) and the closing or switching means (8, 11).
- 3. The charged internal combustion engine (1) of claim 2, wherein the control of the supplemental compressor (4) is a subsystem in the central internal combustion engine control (41).

- 5. The charged internal combustion engine (1) of claim 1, wherein the control means for the supplemental compressor (40) is separate from the internal combustion engine control (41).
- 6. The charged internal combustion engine (1) as in claim 5, wherein the parameters monitored as to the engine operational condition provide an input value for the control electronics.
- 7. The charged internal combustion engine of claim 1, wherein the control (40) of the supplemental compressor (4) is a subsystem of the vehicle system.
- 8. The charged internal combustion engine (1) as in claim 7, wherein the partial systems are connected to each other with a bus system (45).
- 9. A charged internal combustion engine (1) including:
(a) at least one stage of charging by a turbocharger (3); (b) at least one supplemental compressor (4) connected to the turbocharger; (c) a heat exchanger (13) arranged downstream of the supplemental compressor; (d) an electric motor drive (5) for the supplemental compressor (4); and (e) at least one closing or switching means (8, 11) provided between the supplemental compressor (4) and the turbocharger (3), wherein an electronic control device (40) is present to regulate operation of the supplemental compressor (4) and the closing or switching means (8, 11).
- 10. The charged internal combustion engine (1) of claim 9, wherein an electronic control device (40) is present to regulate operation of the supplemental compressor (4) and the closing or switching means (8, 11).
- 11. The charged internal combustion engine (1) of claim 10, wherein the control (40) of the supplemental compressor (4) is a subsystem in the central internal combustion engine control (41).
- 12. The charged internal combustion engine (1) of claim 11, wherein, wherein the partial systems are connected to each other with a bus system (45).
- 13. The charged internal combustion engine (1) of claim 9, wherein the control means (40) for the supplemental compressor (4) is separate from the internal combustion engine control (41).
- 14. The charged internal combustion engine (1) as in claim 13, wherein the parameters monitored as to the engine operational condition provide an input value for the control electronics.
- 15. The charged internal combustion engine of claim 9, wherein the control (40) of the supplemental compressor (4) is a subsystem of the vehicle system.
- 16. The charged internal combustion engine as in claim 15, wherein the partial systems are connected to each other with a bus system (45).
- 17. A charged internal combustion engine (1) including:
(a) at least one stage of charging by a turbocharger (3); (b) at least one supplemental compressor (4) connected to the turbocharger; (c) an electric motor drive (5) for the supplemental compressor; and (d) at least one closing (11) or switching (8) means provided between the supplemental compressor (4) and the turbocharger (3), wherein an electronic control device (40) is present to regulate operation of the supplemental compressor (4) and the closing (11) or switching (8) means, and wherein the supplemental compressor (4) is used as a secondary air pump to supply air to a catalytic converter.
- 18. A charged internal combustion engine (1) including:
(a) at least one stage of charging by a turbocharger (3); (b) at least one supplemental compressor (4) connected to the turbocharger; (c) an electric motor drive (5) for the supplemental compressor; and (d) at least one closing (11) or switching (8) means provided between the supplemental compressor (4) and the turbocharger, wherein an electronic control device (40) is present to regulate operation of the supplemental compressor (4) and the closing (11) or switching (8) means, and wherein at least one supplemental compressor (4) with at least one compression stage is connected in parallel with the turbocharger.
