为了节省燃料,在汽油机上曾用过二次雾化、三重喉管化油器等各种措施.近几年来,增强进气旋量以促进混合气完全燃烧,已受到国内外汽车行业的普遍重视.Lescor和Swarup是国外期刊介绍的两种汽油机用的旋流圈(简称L、S旋流圈),我们将L、S两种旋流圈装在解放牌汽车上作了引用试验,经过一段时间的使用,证明效果良好. 从行车的试用和实验室的模拟试验证明,在进气管以前产生的旋流,经进气管分流后进入支管时,燃油微粒的公旋量(螺线冲量)已绝大部分衰减;微团质点的自旋量(自转动量)进入支管后再运行到气门口时,经过三次换向阻尼,也基本上衰减为自由状态.就整个进气道来说(从化油器到燃烧室),靠近化油器的部分,不希望有过强的单向旋流,所希望的倒是扰流或冲击紊流,即希望在这个区间具有S旋流圈的效应.在靠近气门口部分,希望得
In order to save fuel, various measures such as secondary atomization and triple-pipe carburetor have been used on the gasoline engine, and in recent years, it has been widely recognized by the automobile industry both at home and abroad to enhance the intake cyclone to promote the complete combustion of the gas mixture .Lescor and Swarup are two kinds of hydrocyclone for gasoline engine introduced by foreign periodicals (referred to as L, S cyclone). We put L, S two kinds of cyclone in Jiefangpai Automobile for reference test. After a period The use of time, proved effective.From the driving trial and laboratory simulation tests show that the cyclone generated before the intake manifold, the manifold into the branch after the intake manifold, the fuel particles of the public spin (spiral impulse) has Most of the decay; the mass of spin group (spin amount) into the branch pipe and then run to the valve port, after three commutation damping, but also basically decay to a free state .As for the entire inlet (Conghua Oil to the combustion chamber), close to the carburetor part, do not want to have a strong unidirectional cyclone, the hope is spoiler or impact turbulence, that is, in this region hope to have the effect of S cyclone. Near the valve part, hope
