Abstract:
The present invention relates to a device for controlling the amount of air fed into the intake of a charged internal combustion engine comprising two exhaust gas outlets (32, 36) which are each connected to an exhaust manifold (30, 34) of a group of at least one cylinder (121, 122, 123, 124). The device comprises a charging device (38) comprising a turbocompressor having a dual-inlet (46, 48) turbine (40) connected to the exhaust gas outlets and an external air compressor (44), and at least one duct for partially transferring compressed air from the compressor to the turbine inlets. According to the invention, the partial transfer duct (100, 102; 110, 112) is integrated into the cylinder head and comprises throttles (74, 76) controlling the circulation of compressed air in said duct.
