关于改喷油嘴的问题
现在网上流行起一种该喷油嘴的浪潮,就是原车4孔的喷油嘴换成12孔甚至18孔的喷油嘴(当然标准测试环境下喷油量大致相当),理由是雾化效果更好,燃烧更充分,减少积碳,一定程度上省油,增强动力。问一下各位大侠是否真有实效?

同压力输出,同样喷油量,前两者不变的条件下却来多了3倍甚至4倍的孔目,你认为雾化会更好? 相同的喷油量,更多的孔目,那所喷出来的油滴直径会不会更细小,更容易完全燃烧,积碳更少?当然可能会带来提早燃烧的隐患。

这个不严谨,堵孔和不堵孔单位时间喷水量不一样,而我看到的改装是单位时间喷油量基本一致,但是孔目数量差很多。 纯物理角度说,进油管压力相同,喷油量相同,孔多的比孔少的,出口压力就小了。
我没用过,只是中学物理还不错,随便分析下

我没用过,只是中学物理还不错,随便分析下 大哥,你还敢说你懂得物理?你考虑到了孔径的大小吗?多孔的孔径一定小,4孔的孔径大。这只是其一。从物理学角度讲,如果真的能保证油从喷油嘴喷出时压力(其实是压强)相同,无论4孔还是12孔,无论孔粗还是孔细,在真空中(我说的是假如没有空气阻力,当然在发动机里更有利于油的喷射了,因为油喷出的空间是负压)喷出的速度是相等的,因为液体的压强p与水的流速V关系如下: p + ρV^2/2 = C 式中C为常数 式中:p--压强; ρ----液体密度;V--流速,这里就不关直径的事。哥们好好学学物理吧,请不要装懂!

拒绝堵塞,痛快淋漓的喷射的一霎那,记更换喷油嘴,洗洗更健康。
& & 天天的为了奶粉钱忙碌奔波,心爱的小六子不知不觉已经8万公里了,期间5000的小保养没有间断过,正时皮带7万也换了,车是2T动力还凑合,就是太娇气,小毛病多些,好在自己对车敏感些,有状况马上维修,至今没掉过链子,有个问题大家注意,我的车因公司业务问题老是换司机开,而且经常怠速空调着车,切忌不可切记不可。但就在前几天还是出了糗,路上发现车子怠速抖动厉害,行驶起来倒是没事,心里想着应该不是汽油的问题,平时95号石化侍候着呢,可能是积碳的问题,马上电话维修店老板,回复我也是要洗洗,看来应该给小六子来点泻药,要不真堵了。
& & 车子出保之后再没去过4S,不想接那飞快的大刀,自己找了个专修奥迪的店铺,每次大小保养都在那,环境肯定比不了4S,但是技术不差,价钱比4S低一半还要拐弯,而且每次修车我喜欢在旁边看着,帮着递这递那,本人小爱好,呵呵。
& & 到了店,2话不说,泻药吊瓶走你,2瓶下去,天也黑了,师傅电脑检测,没有痊愈,可是我这还有事,就开了车先走了,快到家的时候抖动加大,心里那个忐忑啊,马上电话维修店,老板告诉我,恐怕光吊瓶不行了,明天赶紧来店吧,第二天一早开始师傅用排除法依次检测火花塞,点火线圈,燃油蒸压泵,都被排除问题了,看来只有喷油嘴了,那就开始拆吧。
