    摘要: The present invention relates to a device for controlling the amount of air fed into the intake of a supercharged internal combustion engine, said engine including two exhaust gas outlets (32, 36) each connected to an exhaust manifold (30, 34) of a group of at least one cylinder (121, 122, 123, 124), said device including a supercharging device (38) comprising a turbocharger having a dual-inlet (50, 52) turbine (40) connected to said exhaust gas outlets as well as an outside air compressor (44), and a duct (64) for partially transferring compressed air from the compressor to the inlets of the turbine. According to the invention, the partial transfer duct includes two branches (70, 72) connected to the inlets of the turbine and each supporting throttling means (74, 76) which control the circulation of compressed air in said branches, and said partial transfer duct is built into the casing of the turbocharger so as to be short between the outlet of the compressor and the dual inlets of the turbine, and thus to be compact and have reduced response time.
