PCT No. PCT/SE95/01460 Sec. 371 Date Jun. 5, 1997 Sec. 102(e) Date Jun. 5, 1997 PCT Filed Dec. 6, 1995 PCT Pub. No. WO96/18030 PCT Pub. Date Jun. 13, 1996A supercharged EGR (Exhaust Gas Recirculation) turbine (6) is incorporated in the exhaust gas flow in series after the turbine (4) of the supercharger and is driven by the exhaust gases which have already passed through the turbine of the supercharger. The EGR turbine (6) is used for driving an EGR compressor (7) which delivers a partial gas flow which is to be returned to the inlet manifold (2) of the combustion engine. The partial gas flow intended for return to the inlet side is tapped from the exhaust manifold (3, 3') and is pressurized in the compressor stage (7). The EGR turbine (6) is controlled by a waste-gate valve (15) and the partial exhaust gas flow to the EGR compressor is controlled by a valve 17. |
