Definitions

  • the invention relates to a turbocharger arrangement according to the preamble of claim 1 and to an internal combustion engine according to the preamble of claim 6.
  • a generic turbocharger arrangement for register charging an internal combustion engine has two load stages arranged parallel to one another, in which the control of the turbine of the second stage is effected by an actuator arranged downstream or upstream of the second turbine, for example in the form of a control flap.
  • the guide vanes of the VTG mechanism serve to close the second turbine of the second charge stage during single-load operation.
  • the vanes of the VTG diffuser may be constructed in a conventional manner in the turbocharger assembly of the present invention and accordingly controllably open in position between a closed position and a fully open position vanes disposed between the exhaust gas outlet side and the turbine wheel of the turbine of the second charger stage are, so that can be adjusted by changing the position of the vanes in its cross section variable flow channels.
  • a registered internal combustion engine is defined, which is provided with a turbocharger assembly according to the invention.
  • the sole figure of the drawing shows a schematically greatly simplified representation of an internal combustion engine according to the invention, which is provided with a turbocharger assembly 1 according to the invention for register charging.
  • the turbocharger arrangement 1 has a first charge stage 2 which comprises a first turbine 3 which is connected via a line 24 to an exhaust manifold 23 of an internal combustion engine 17.
  • the first turbine 3 is provided with a bypass line 8 with an associated control element, for example in the form of a control valve or a control flap.
  • the turbine 3 is connected to a first compressor 4 in the usual way via a shaft in connection.
  • the compressor 4 has an inlet 13 and an outlet 26 which communicates via a line 27 and a charge air cooler 18 with the intake manifold or an intake manifold 16 of the internal combustion engine 17, which in the exemplary case as a four-cylinder engine with four cylinders 19 to 22 is formed, but in principle may be any other type of internal combustion engine.
  • the turbocharger arrangement 1 furthermore has a second charge stage 5 which comprises a second turbine 6 and a second compressor 7 connected to the second turbine 6 via a shaft, the output 10 of which is connected via a connecting line 11 and a control member 12 to the input 13 of the first compressor 4 can be brought into connection or optionally via a bypass line 14 with an associated control member 15 via the intercooler 18 with the intake manifold 16 of the Internal combustion engine 17 can be associated.
  • a second charge stage 5 which comprises a second turbine 6 and a second compressor 7 connected to the second turbine 6 via a shaft, the output 10 of which is connected via a connecting line 11 and a control member 12 to the input 13 of the first compressor 4 can be brought into connection or optionally via a bypass line 14 with an associated control member 15 via the intercooler 18 with the intake manifold 16 of the Internal combustion engine 17 can be associated.
  • the second turbine 6 of the second charger stage 5 is designed as a VTG turbine having adjustable vanes (not shown) and serving as a control device for the turbocharger arrangement 1 shown in the figure, since the vanes of the turbine 2 are between a closed position and a turbine fully open position can be adjusted.
