这里有你不知道的汽车维修保养知识,更有那些假象背后的真实故事。关于汽车那些已知的、未知的、好奇的、懵懂的、你都可以在这里找到答案!
清洗节气门几乎是所有汽车都应该做的事儿,但是很多车主还真的不一定知道为什么要洗节气门。对汽车有怎么样的影响,更是不清楚。
本期小编就带大家解读:为什么节气门脏了就要洗?
一什么是节气门?
节气门是发动机重要组成部件,从名字也能看的出来,它的功能更接近于一扇门。主要是作用就是,控制发动机进气量的大小。
二节气门在车身上哪个位置?
节气门是发动机的部件,自然离不开发动机。一般情况下都是位于空滤谐振箱和进气道之间,在车身上还是比较容易看见的。
三节气门变脏之后会怎么样?
节气门相当于人的咽喉,对性能自然有着很大的影响。从发动机控制理论的层面上讲,节气门脏了之后,首先进气量会减小,也就是进入发动机里的气变少了。反应到驾驶感受上,主要有以下三个方面。
1油耗增加
进气量变少,就会造成混合气过浓。燃油根本没有足够的空气来进行燃烧,就会出现费油的现象。
2发动机抖动
混合气对发动机的影响是巨大的,进气量变少之后,还会导致发动机抖动。特别是在热车怠速的时候,发动机就会出现怠速不稳的现象,来回抖动。
3加速无力
或许你想不到,节气门脏了还会导致发动机加速无力吧,其实这才是节气门脏了之后最大的表现。行驶的汽车就像是在长跑的运动员,你往运动员嘴里赛一块苹果,看看他还能不能跑得动。节气门脏了,跟塞苹果是一个原理。
四节气门到底应该怎么清洗?
为此小编特意找了一个变脏的节气门演示正确的清洗方法。看到右上角的小窗了吗,灰尘主要聚集在节气门的翻板处,要清洗的位置主要就是节气门的翻板。
现在大多数的车型都是不需要拆卸节气门就可以进行清洗的。在清洗节气门的时候,其实只需要用一块抹布将节气门的翻板擦拭干净即可。
当然,还有很多车型的节气门是没法在车身上进行清洗的,必须要拆卸下来才行,例如宝马的N55发动机。很多许久没有清洗过节气门的车辆,节气门的灰尘会变得很硬,难以清除,这个时候就需要借助清洗剂了。
清洗剂一定要用专用的,现在的很多清洗剂腐蚀能力很强,对电路板伤害很多大。很多车的节气门都是在清洗后出现的了问题,一般情况下都是洗坏的。
五节气门多久需要清洗一次?
节气门没有固定的清洗周期。小编建议每两次保养,就检查一次节气门,如果脏了就要清洗。当然,能不拆的就尽量不拆,因为拆和不拆清洗的效果是一样的,但是拆的工时费明显要高一些。
没想到小巧的节气门,还有这么多的知识点。
