摘要： An opposed-piston engine has a plurality of intake ports wrapped around the cylinder wall. It is desirable to obtain high swirl ratio flow with minimal pressure drop. A system have a generally-volute shaped plenum is disclosed. A centerline of the volute spirals inwardly. Furthermore, the cross-sectional area of the volute decreases in the direction of flow. The area is decreased as the flow from the plenum enters intake ports so that the velocity of flow in the plenum near the downstream end does not slow precipitously. The intake system may have multiple such volute-shaped plena coupled to mutually exclusive subsets of the intake ports. The volute shape leads to a high swirl ratio with limited drop in flow energy.
