mi; Plus some gauge is not accurate, you can never know how long a tank of gas
can last unless you drive your car till the gas runs out...
Another way to tell is to look at how much you pump into your tank in a gas
station. If the needle indicates an empty tank but pump indicates a 80%
capacity that means your car has 20% more gas in it. So you can add 20% to
your mileage. Very easy to calculate.
一箱油能跑到500-600mile,凭我的经验 | c******k 发帖数: 1 | 2 汽车的油耗可以查原厂说明书,上面都有,如果与原厂说明书
相差很远,一般情况下,那就是发动机氧传感器出问题。
氧传感器有两个,一个在发动机盖下排气管上, 很容易更换,
5分钟搞定,还有一个在车底下排气管上面,比较麻烦,要钻
下去,自己也能 换,我就是自己换的。氧传感器彻底失灵时汽车
“check engine”灯会亮,但是没有警告的时候可能早已经坏了。
发动机怠速时用万用表量一下氧传感器上面电压, 应该在零点
几伏左右,如果没有电压就是坏了。
单线的氧传感器大概要25块,三线的大概要75块。 送车行修的话
你得花200块钱左右。
汽车上的很多东西你自己都无法修,氧气传感器是少数几个自己可以
彻底搞定的东西之一。 |
