Abstract
An air intake system for an internal combustion engine. The intake system has a cylinder head delimiting at least one cylinder, an intake manifold which has at least one air passage per cylinder, and at least one intake passage in the cylinder head per cylinder, with an intake port leading into the associated cylinder. The intake manifold has a cylinder head flange connected to the cylinder head so that each air passage of the intake manifold is in fluid-conductive connection with an associated intake passage in the cylinder head. A flap valve is operatively arranged in the air passage so as to constrict a cross section of the air passage of the intake manifold. A partition wall is arranged in the intake passage so as to divide the intake passage over a predetermined distance between the cylinder head flange and the intake port. The flap valve is movable between an open position and a closed position and is configured so as to project over the cylinder head flange so that the flap value strikes the partition wall when it is in the closed position in which the flap valve constricts the cross section of the air passage.
