Abstract

In an exhaust gas turbocharger for a reciprocating internal combustion engine comprising an exhaust gas turbine in the exhaust line and a compressor in the inlet line of the engine, the exhaust gas turbine has two exhaust gas flow passages, by way of which exhaust gas is fed to the turbine rotor, the ratio of the turbine rotor diameter to the compressor wheel diameter being set by a function, which is dependent on the displacement volume of the internal combustion engine.
