Abstract

In an internal combustion engine provided with two exhaust gas turbochargers which each comprise a turbine in an exhaust line and one compressor in an intake section of the engine, two exhaust lines are provided which are each assigned to at least one of the exhaust gas turbines, an exhaust gas recirculation device being arranged between an exhaust line upstream of an exhaust gas turbine and the intake section downstream of a compressor and the two exhaust lines including bypass lines with a control valve for selectively permitting the exhaust gas to bypass the turbine closer to the engine.
