    Abstract: 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.

    Abstract: 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.

    Abstract: An exhaust-gas turbocharger in an internal combustion engine having a compressor in the induction tract and an exhaust-gas turbine in the exhaust-gas line wherein the exhaust-gas turbine has at least two spiral ducts which in each case open into a radial flow inlet passage. Arranged in the radial flow inlet passage is a guide cascade ring which is disposed between two axially delimiting walls. One of the walls is designed to be axially displaceable and adapted to accommodate the vanes of the guide cascade ring. The wall is displaceable axially outward to such an extent that the vanes of the radial guide cascade ring are no longer in contact with the wall and there is a direct, unobstructed flow path to an outflow duct in the exhaust-gas turbine.
