Apparatus and a process for supplying recirculated exhaust gases to incoming air to a piston-type internal combustion engine. The apparatus includes a duct (2) for incoming air and a feed pipe (1) for exhaust gases and is especially well characterized in that the feed pipe (1) opens out into an outlet section (3) having at least one outlet (4) for the supply of the exhaust gases, which outlet section constitutes an outlet path (a) extended in the longitudinal direction of the duct.
