    124) The unit of (30,

         34), which comprises a charging device (38) comprising a turbocharger with a double-inlet turbine (40), which is connected to the exhaust gas outlet, and an external air compressor (44), and which device comprises a partial transfer conduit (64) for transferring compressed air from the compressor section to the inlet of the turbine, characterized in that the partial transfer conduit comprises two branches (70,

         72) connected to the inlet of the turbine, which branches are connected to different inlets of the turbine, respectively, and which branches each carry a first valve regulating device (74,

         76) controlling the passage of compressed air in these branches, wherein one branch (70) of each branch is connected to the other branch (72) by a connecting line (84), wherein the partial transfer conduit (64) carries a device (88) for heating compressed air and the two branches (70,

         72) are located downstream of the device (88) for heating compressed air, the partial transfer conduit extending from the outlet of the external air compressor (44) being divided into the two branches (70,

         72) after the device for heating compressed air and not being branched before the device for heating compressed air, so that all air on the partial transfer conduit can be heated by means of the device (88) for heating compressed air, and wherein the connecting line (84) is provided between the valve regulating device and the exhaust gas outlet of the internal combustion engine.
