Definitions

  • the invention relates to a turbine for an exhaust gas turbocharger of the type indicated in the preamble of patent claim 1.
  • Wegmondem exhaust gas is adjustable.
  • the exhaust gas flows according to a directional arrow 52 to an exhaust gas recirculation cooler 50, by which the exhaust gas is cooled before it is supplied according to a direction arrow 48 of the sucked from the internal combustion engine 10 air.
  • This admission of the intake air with the recirculated exhaust gas leads to a reduction of emissions, in particular of nitrogen oxide and particulate emissions, of the internal combustion engine 10, as a result of which it not only has low fuel consumption, high performance but also low emissions.
