Exhaust gas recirculation system 10 comprising an internal combustion engine 12, a gas intake for the internal combustion engine comprising an intake pipe 16 and an intake manifold 18, a gas exhaust for the internal combustion engine comprising an exhaust manifold 20, an exhaust pipe 22, an EGR pipe 34 connected to the gas exhaust extending to the gas intake and a turbocharger 24 being connected to the gas intake and the gas exhaust The turbocharger comprises an electric device 46 being designed to be driven by the exhaust gas. Preferably the electric device may be driven by a shaft of the turbocharger and can work as a generator, store electric energy and work as an electric motor. There may be a bypass, comprising a wastegate, in the exhaust pipe able to bypass the turbocharger and the EGR pipe, where an EGR cooler and/or an EGR valve are connected to the EGR pipe. A turbocharger is also claimed. |
