Abstract
The invention relates to a variable swirl generating intake manifold with at least one longitudinally oriented partition wall that forms at least one swirl generating first manifold section and one swirl stopping second manifold section, said manifold sections only meeting again in the valve area, at least the second manifold section being, for the purpose of increasing the swirl, at least partially closable in the entrance area by means of a control flap that is pivotal about an axis, said axis being substantially arranged in the plane of the partition wall, said control flap having two arms and said two manifold sections being at least partially closable in a first rotational end position and open in a second rotational end position. To permit in the simplest possible way to both vary the swirl and throttle the intake charge there is provided that, for providing an increase in swirl, the control flap may be deviated from the second rotational end position toward a third end position by closing at least partially the second manifold section.
