This invention relates to an intake system for a multi-cylinder internal-combustion engine operating with exhaust gas recirculation and fuel injection, having an air-guiding casing that is developed in the shape of a box and has a partition that, on the one side, is the wall part for a clean-air side and, on the other side, is a wall part for a mixing duct and a distributor volume that has connecting points for suction pipes of the internal-combustion engine. In the partition, an air-throttle valve is disposed centrally that controls the air inlet into the mixing duct, and downstream of the valve and concentrically to it, the inlet for recirculated exhaust gas is arranged. Passages that extend in an arched course and are located symmetrically with respect to the position of the air-throttle valve connect the mixing duct with the distributor volume.
