  • Patent number: 6216666
    Abstract: In an intake passage arrangement in an internal combustion engine at least two intake ports located in a cylinder head depart from a common intake flow path. In the area where the flow path branches into the separate intake ports a swirl control device configured as a control flap is positioned, which is rotatable about a rotation axis situated at one end of the control flap. In one position the control flap opens both intake ports, whereas it blocks one intake port in another position. To ensure control of the swirl motion of the intake flow entering the combustion chamber and to permit a most simple and compact design an intermediary part carrying the control flap is essentially configured as a thin, flat frame, and preferably as a die-cast part made of aluminum.
