The results show that at any Angle between axes of inclined swirl control valve and crank shift, flow coefficient and inclined swirl ratio increase gradually with increase of valve opening.
Lastly, the strength of inclined-axis swirl is directly proportional to the Shadowed area of the single channel except for the S1 valve position where the in-cylinder motion is only tumble.
除具有纯滚流特点的S1阀片位置外，缸内气体斜轴涡流运动强度与单边气道截面被遮住的面积成正比。

Butterfly valve according to the structure of the form of bias can be divided into the plate, vertical plate, inclined plate and leveraged.
