Abstract

Embodiments of an internal combustion engine are provided. In one example, an engine includes at least one cylinder, an intake system for supplying charge air to the at least one cylinder, an exhaust-gas discharge system for discharging exhaust gas from the at least one cylinder, a first exhaust-gas turbocharger including a first turbine arranged in the exhaust-gas discharge system and a first compressor arranged in the intake system; and an exhaust-gas recirculation (EGR) system. The EGR system includes a line which branches off from the exhaust-gas discharge system and opens into the intake system, a second exhaust-gas turbocharger comprising an EGR turbine arranged in the line on a shaft and an EGR compressor arranged in the line on the shaft upstream of said EGR turbine, and an EGR cooler positioned between the EGR turbine and the EGR compressor.
