Abstract
In a throttlable induction manifold of an internal combustion engine a variable geometry whirler for homogenizing an explosive charge flowing there in, during a partially closed throttle operation, the geometry of said whirler adapted to change during an open throttle operation so that the whirling action and the flow restriction associated therewith are minimized.
Claims7
In an internal combustion engine having a combustion chamber, an induction manifold for delivering an explosive charge into said chamber and a throttle means disposed in said manifold for selectively and variably closing and restricting flow through said manifold,
- the improvement wherein a variable geometry whirling creating apparatus is disposed in said manifold for mixing and homogenizing said explosive charge when said throttle is partially open, said apparatus adapted to vary its geometry and to minimize its whirling creating action when said throttle is fully open.
