Device for recycling of exhaust gas

Such a device for an internal combustion engine supercharged by a turbocharger comprises an exhaust gas turbine 8 and a compressor 1, an exhaust-gas 7a, 7b, a charge air conduit 5 and a recirculation exhaust gas 16 which connects the exhaust-gas before the turbine to the charge-air pipe 3 downstream of the compressor. The turbine turbofan. channels of the two streams are of asymmetrical design. The turbine has a variable geometry to vary the flow rate of exhaust gas. With a regulating system 21, the pressure in the return line of the exhaust gas can be controlled to be set at a higher value than the pressure in the charge air after the compressor.
