Abstract
An exhaust gas turbocharger for an internal-combustion engine, whose exhaust gas turbine has a rotor disk with at least one semiaxial and one radial flow inlet cross-section, and is provided with a variable turbine geometry for the variable adjustment of at least one flow inlet cross-section. Furthermore, a compressor is provided in the intake system of the internal-combustion engine. In order to improve the efficiency of the exhaust gas turbocharger in a wide operating range, the ratio of the compressor outlet diameter to the average turbine inlet diameter can be variably adjusted according to the adjustment of the variable turbine geometry between a minimal value and a maximal value, the minimal value being lower than 1.1.
