In an arrangement for recirculating exhaust gas in a four-stroke internal combustion engine, especially a diesel engine, having a cylinder with intake and exhaust valves and means for timely opening the intake and exhaust valves during the engine intake and exhaust strokes, the means for opening the intake valves include supplementary means for actuating the intake valves also during the engine exhaust stroke in a timed manner such that a portion of the exhaust gas is discharged into the engine intake manifold to be subsequently recirculated into the cylinder during the next intake stroke.
