A channel is disclosed for recirculating a portion of an engine exhaust gas to the induction passage has an intermediately arranged converging-diverging supersonic nozzle with a valve member arranged in the nozzle to vary the cross-sectional area of the channel at the throat, so that the mass flow rate of the recirculated exhaust gas depends solely on the cross-sectional area so far as the gas velocity at the throat is sonic.
