PCT No. PCT/SE95/01461 Sec. 371 Date Jun. 5, 1997 Sec. 102(e) Date Jun. 5, 1997 PCT Filed Dec. 6, 1995 PCT Pub. No. WO96/18031 PCT Pub. Date Jun. 13, 1996In a supercharged engine, an EGR (Exhaust Gas Recirculation) turbine (6) is incorporated in the exhaust gas flow in parallel with the turbine (4) of the supercharger. The EGR turbine (6) is driven by a first partial exhaust gas flow (21) and is used for driving an EGR compressor (7) which delivers a second partial gas flow (22) which is to be returned to the inlet manifold (2) of the combustion engine. The first and second partial gas flows (21,22) intended respectively to drive the EGR turbine (6) and be returned to the inlet side via the EGR compressor (7) are both tapped from the exhaust manifold (3,3') upstream with respect to the supercharger turbine (4) as seen in the exhaust gas flow direction. The exhaust gas flows through the EGR turbine (6), and the EGR compressor (7) are controlled by individual control valves (15,17). |
