    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.

    摘要: In an internal combustion engine including an exhaust turbocharger and an exhaust-gas recirculation device, with an exhaust turbine and a compressor, the exhaust turbine has a plurality of inlet flow passages to which exhaust gas can be supplied via separate exhaust lines connected to some of the cylinders of the internal combustion engine. In total, three flow passages are provided in the exhaust turbine, of which two communicate with the exhaust-gas recirculation device, and one of these flow passages includes an adjustable throttling member for regulating the mass flow of exhaust gas to be recirculated.
