A turbocharged internal combustion engine includes a supercharging air compressor that delivers compressed air to the engine via a compressed air delivery conduit, the compressor being coupled to an exhaust gas turbine having an inlet connected to the exhaust manifold of the engine via an exhaust gas conduit and an outlet, a bypass conduit connecting the compressed air delivery conduit to the exhaust gas conduit, and is characterized by an energy recovery device comprising an auxiliary vapor generator having a heating fluid side with an inlet connected to the outlet of the exhaust gas turbine and having a heated fluid side with an outlet connected to an inlet of an auxiliary vapor turbine via an auxiliary vapor conduit, and a heat exchanger traversed by the bypass conduit and inserted in the auxiliary vapor conduit for preheating the bypassed compressed air by excess heat of the auxiliary vapor prior to delivering the auxiliary vapor to the auxiliary vapor turbine.
