发现四气门汽油机各缸产生的最大滚流轴线与曲轴轴线夹角是不同的。
The results show that the Angle between maxi - mum tumble axis and crank axis generated by each cylinder in a four-valve gasoline engine varies.
随着发动机转速升高，单侧进气EGR在缸内气体作用下形成滚流分层越明显。
The tumbling flows stratify of the side jet EGR is more obviously as the speed of the engine increases.
用热线风速仪研究了缸内滚流的形成过程，发现滚流轴线与水平面的夹角随气门升程的增大而增大。
It is found that the Angle between tumble axis and horizontal plane increases with valve lift. The "tumble" is not a pure tumble, but is a inclined swirl.
