There's always a smell of gasoline in the car? It may not be the car, but yourself. I don't know if you have the impression that a person's car is always filled with a strong smell of gasoline. Whether he drives a new car or an old car, or whether you always find that you always smell bursts of gasoline in your car. Sometimes when driving at high speed, the smell of gasoline suddenly emits for a period of time, I was so scared that I stopped the car by the side of the road to check whether there was oil leakage, but I didn't find any clues.

那么这种汽油味究竟是从何而来呢？其实大部分情况是，加油加得太满，很多人有这个习惯，加油加满箱，而且加满后跳枪还要将加油枪拔出来再跳几次才肯善罢甘休，直到从加油口就可以看到汽油液面。这才是造成自己车里总有汽油味的罪魁祸首。

So where does this gasoline smell come from? In fact, in most cases, the refueling is too full. Many people have this habit. Fill up the tank, and jump the gun after filling up. They have to pull out the refueling gun and jump several times before they are willing to give up until the gasoline level can be seen from the filler. This is the culprit who always smells of gasoline in his car.

原来，当汽油加的过满，汽油就有可能顺着油路窜入碳罐，而碳罐的作用，原本是用来吸收汽油蒸汽，当浸入汽油后，就有可能从通风孔向外过度散发汽油蒸汽，特别是当空调处于外循环状态时，汽油味尤其严重。

It turns out that when the gasoline is overfilled, the gasoline may rush into the carbon canister along the oil path, and the function of the carbon canister was originally used to absorb gasoline vapor. When immersed in gasoline, it may excessively emit gasoline vapor from the vent, especially when the air conditioner is in the external circulation state, the gasoline smell is particularly serious.

因此，如果油加的太满导致散发出汽油味，应该将空调循环模式短暂调节内循环，待到一段时间过后，消耗了一定的燃油后，再开启外循环，就不会出现刺鼻的汽油味了。那么，除此之外，还有哪些情况会造成汽油味散发？

Therefore, if the oil is too full, resulting in the smell of gasoline, the air conditioning cycle mode should be briefly adjusted to the internal cycle. After a period of time, after consuming a certain amount of fuel, open the external cycle, and there will be no pungent smell of gasoline. So, in addition, what else will cause the smell of gasoline?

就是汽油管渗漏问题，如果汽油管出现渗漏，那么汽油味理所应当的会随着空调系统进入车内，其渗漏的部位一般出现在管路接口处，这个我们从日常检查中是可以看出来的，渗漏出来的汽油在经过一段时间后会大量吸附灰尘从而形成厚厚的油泥。

The first problem is the leakage of the gasoline pipe. If the gasoline pipe leaks, the gasoline flavor should enter the vehicle with the air conditioning system, and the leakage part usually appears at the pipeline interface. We can see from the daily inspection that the leaked steam and oil will absorb a lot of dust after a period of time to form a thick sludge.
