    摘要： An exhaust gas turbocharger for an internal combustion engine comprises a turbine in the exhaust line and a compressor, which is driven by the turbine and which is located inside the intake tract of the internal combustion engine. The turbine comprises a flow duct having a radial flow entrance cross-section, and a flow ring is provided that delimits the flow entrance cross-section. An adjustable vane is placed in the radial flow entrance cross-section for variably adjusting this flow entrance cross-section. The flow ring inside the housing of the exhaust gas turbine can be axially displaced between a contact position toward the vane and a position that frees a gap toward the vane.

    摘要： An exhaust turbocharger for an internal combustion engine has a main compressor for compressing the fresh air supplied to the engine, an additional compressor for compressing combustion gases to be recycled to the engine, and a turbine that can be driven by the exhaust gases from the engine and which serves to drive the main compressor and the additional compressor. The turbine has an adjustable geometry which facilitates optimization of engine operation regarding pollutant emissions, fuel consumption, and performance.

    摘要： An exhaust gas turbocharger for an internal combustion engine, which has an exhaust gas turbine in the exhaust system and a compressor in the induction system, comprises a variable turbine geometry, associated with the turbine, for adjustably setting a radial inlet cross section for the flow to the turbine rotor. The variable turbine geometry is configured as a guide cascade ring, which has guide vanes distributed over the periphery and encompasses the turbine rotor. The minimum distance between two adjacent guide vanes obeys a specified relationship with respect to the diameter of the turbine rotor and the number of guide vanes of the guide cascade ring. In addition, a flow edge is provided on the radially inner surface of each guide vane.
