Intake system

The device has an insert (20) to divide an intake channel (14) into two separate flow cross sections (21,22). The insert is fitted into a holder (29) in cylinder head flange (15). The insert has a divider wall (23) to separate the two sections. The air collector, intake channels, and cylinder head flange are formed by two sealed connected half shells (10,11). The insert also contains a closure flap (24) on a shaft. The shafts of all intake channels are connected to a single movement device. Insert and closure flap are formed in an injection process.
