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, wherein the supplemental compressor is integrated into an intake pipe assembly (18); (c) an electric motor drive (5) for the supplemental compressor (4); 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.
- 2. The charged internal combustion engine (1) as in claim 1, wherein the supplemental compressor (4) is integrated into an intake pipe (17).
- 3. The charged internal combustion engine (1) as in claim 1, wherein the supplemental compressor (4) is mounted on the intake pipe (17).
- 4. The charged internal combustion engine (1) as in claim 1, wherein a spiral air guide is formed around the compressor wheel directly in the component incorporating the compressor.
- 5. The charged internal combustion engine as in claim 1, wherein the drive of the supplemental compressor (4) is mounted with vibration decoupling in the assembly which incorporates the supplemental compressor (4).
- 6. The charged internal combustion engine as in claim 1, wherein the assembly includes the closing (11) or switching means (8) behind the supplemental compressor (4).
- 7. The charged internal combustion engine (1) as in claim 1, wherein the assembly includes a secondary air conduit (12).
- 8. The charged internal combustion engine (1) as in claim 1, wherein the assembly includes an exhaust gas return (16).
- 9. The charged internal combustion engine (1) as in claim 1, wherein the assembly includes an engine ventilation.
- 10. The charged internal combustion engine as in claim 1, wherein the assembly includes an onboard diagnostic monitoring device and/or the sensors thereof.
- 11. 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 (11) or switching (8) means (20).
- 12. The charged internal combustion engine (1) of claim 11, wherein the control (40) of the supplemental compressor (4) is a subsystem in the central internal combustion engine control (41).
- 13. The charged internal combustion engine (1) of claim 12, wherein, wherein the partial systems are connected to each other with a bus system (45).
- 14. The charged internal combustion engine (1) of claim 1, wherein the control means (40) for the supplemental compressor (4) is separate from the internal combustion engine control (41).
- 15. The charged internal combustion engine (1) as in claim 14, wherein the parameters monitored as to the engine operational condition provide an input value for the control electronics.
- 16. The charged internal combustion engine of claim 1, wherein the control (40) of the supplemental compressor (4) is a subsystem of the vehicle system.
- 17. The charged internal combustion engine (1) as in claim 16, wherein the partial systems are connected to each other with a bus system (45).
- 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 (3); (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 is present to regulate operation of the supplemental compressor (4) and the closing (11) or switching (8) means, and wherein the drive of the supplemental compressor is coupled to a coolant circuit of the internal combustion engine in such a manner that the heat generated by the drive is dissipated.
- 19. 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 (3); (c) an electric motor drive 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 is present to regulate operation of the supplemental compressor (4) and the closing (11) or switching (8) means, and wherein the supplemental compressor and the turbocharger draw from the same intake area (10).
