Abstract
An intake device for supplying combustion air to an internal combustion engine composed of two sealingly connected half shells (10, 11) which form an intake air plenum (13), intake ducts (14), and a cylinder head flange (15) in which there is an insert (20) associated with each intake duct (14). Each insert is provided with a partition (23) for dividing the flow into two flow cross-sections (21, 22). The first flow cross section (21) is provided with a valve flap (24), which can be opened and closed to influence the filling of combustion chambers of the internal combustion engine.
