Through the analysis of different cross section flow field in cylinder of two-valve and four-valve diesel engine, the following conclusion can be obtained: The formation of intake swirl of two-valve diesel engine mainly is effected by an intense air flow ring zone near the radius from valve axis to cylinder axis, as the flow progresses down through the cylinder, the ring zone air flow expends to both side and finally forms an unified rigid rotating swirl motion.

2号缸盖的螺旋进气道产生的绕自身气门轴线的动量矩比1号缸盖的大，且切向气道的径向速度在前峰面上的数值比1号缸盖的速度数值大很多，因此，两进气道组合后的动量矩损失也大，所以虽然2号缸盖的两个进气道单独的涡流比都高于1号缸盖的两个进气道，但组合后的合成涡流比却是基本相同的。

X axis: The Equation of Time, Y axis: Declination
