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.

那么這種汽油味究竟是從何而來呢？其實大部分情況是，加油加得太滿，很多人有這個習慣，加油加滿箱，而且加滿后跳槍還要將加油槍拔出來再跳幾次才肯善罷甘休，直到從加油口就可以看到汽油液面。這才是造成自己車里總有汽油味的罪魁禍首。

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.

原來，當汽油加的過滿，汽油就有可能順著油路竄入碳罐，而碳罐的作用，原本是用來吸收汽油蒸汽，當浸入汽油后，就有可能從通風孔向外過度散發(fā)汽油蒸汽，特別是當空調(diào)處于外循環(huán)狀態(tài)時，汽油味尤其嚴重。

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，如果油加的太滿導致散發(fā)出汽油味，應該將空調(diào)循環(huán)模式短暫調(diào)節(jié)至內(nèi)循環(huán)，待到一段時間過后，消耗了一定的燃油后，再開啟外循環(huán)，就不會出現(xiàn)刺鼻的汽油味了。那么，除此之外，還有哪些情況會造成汽油味散發(fā)？

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?

首先就是汽油管滲漏問題，如果汽油管出現(xiàn)滲漏，那么汽油味理所應當?shù)臅S著空調(diào)系統(tǒng)進入車內(nèi)，其滲漏的部位一般出現(xiàn)在管路接口處，這個我們從日常檢查中是可以看出來的，滲漏出來的汽油在經(jīng)過一段時間后會大量吸附灰塵從而形成厚厚的油泥。

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.
