ABSTRACT:
Control of cylinder swirl in an internal combustion engine is provided by a swirl generating inlet port having a movable wall to vary the cross-sectional area of the port in a swirl portion surrounding the valve axis. In a preferred embodiment, a wall of thin flexible spring material extends the length of the port and is tensioned or released to vary the flow area.
