Abstract:
The present invention relates to a device for controlling the amount of air fed to the intake of a turbocharged internal-combustion engine comprising a turbocharging system including a turbocharger (7) with a turbine (8) connected to at least one exhaust gas outlet of said engine, as well as an outside air compressor (10), a line (15, 18) for partial transfer of the compressed air from the compressor to the turbine inlet, and an EGR line (18, 21) between an exhaust gas outlet and a compressed air intake line (4). The device is characterized in that the partial transfer line and the EGR line share at least one common portion (18).
