    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.

    摘要: A twin scroll turbocharger device for an internal combustion engine comprising a turbine and a compressor wherein the turbine comprises a first turbine scroll and a second turbine scroll, and wherein at least said first turbine scrolls is provided with a turbine scroll inlet valve such that the exhaust gas flow through the first turbine scroll is controllable. The twin scroll turbocharger device is further characterized in that a bypass conduit is provided between a compressor and at least the first turbine scroll. The bypass conduit is provided with a bypass conduit valve such that a flow through said bypass conduit is controllable.
