Abstract

The disclosure relates to a supercharged, direct-injection internal combustion engine having an intake system for the supply of charge air and having an exhaust-gas discharge system for the discharge of exhaust gas and having at least two series-connected exhaust-gas turbochargers which each comprise a turbine arranged in the exhaust-gas discharge system and a compressor arranged in the intake system and of which a first exhaust-gas turbocharger serves as a low-pressure stage and a second exhaust-gas turbocharger serves as a high-pressure stage, a first bypass line being provided which branches off from the exhaust-gas discharge system between the first turbine and the second turbine so as to form a first junction point.
