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。
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.
水平方向的涡流、轴线方向的滚流以及湍动能的这种分布特性都有利于燃油的雾化以及与空气的混合。
Horizontal swirl, axial tumble and the distribution of turbulent kinetic energy are very important for fuel atomization and mixture formation.
