Summary:In an internal combustion engine comprising an exhaust gas turbocharger, which includes a compressor with a compressor wheel arranged in an inlet tract of the internal combustion engine and a turbine with a turbine wheel coupled rotationally to the compressor wheel and arranged in an at least two-path exhaust gas tract of which is connected to an exhaust gas guide section of the turbine including at least a first spiral channel coupled to the first exhaust path and a second spiral channel coupled to a second exhaust gas path, two guide vane elements are arranged upstream of the turbine wheel and downstream of respective spiral channels which are formed corresponding to a first degree of asymmetry A1 determined as a quotient Θ of a first mass flow parameter and a second mass flow parameter which is between 0.4 and 0.8.
