Abstract

In an exhaust gas recirculation arrangement for an internal combustion engine with an air intake duct for supplying air to the engine, an exhaust gas recirculation pipe extending into the air intake duct for recirculation exhaust gas to the air intake duct and a disc valve arranged in the exhaust gas recirculation pipe for closing the exhaust gas recirculation pipe, the exhaust gas recirculation pipe has a pipe section which extends in the air intake duct in a downstream direction from the disc valve and has, at its downstream end, a nozzle-like discharge opening for discharging exhaust gas into the air intake duct.
