    加油時揭開油箱蓋有氣是怎么回事?

    來源:http://www.philiprobert.com發布時間:2020-11-12 17:26:59

    先分析一下為什么會有聲音,其實主要是由于油箱里面和外面的壓力不同引起的。通常,汽車油箱中的碳罐都有通氣平衡內外氣壓的作用。當碳罐出現問題之后,油箱蓋若沒有泄壓的作用,則會導致壓力不平衡的情況。
    First of all, analyze why there is noise. In fact, it is mainly caused by the different pressure inside and outside the fuel tank. Usually, the carbon tank in the car tank has the function of ventilation to balance the internal and external air pressure. If the fuel tank cap has no pressure relief effect after the carbon tank has problems, it will lead to pressure imbalance.
    其次,出氣聲通常會在夏天出現,因為夏季的溫度比較高,汽油受熱后會發生膨脹,因車輛空間是固定的,密封在內的油氣會出現壓力,里面的壓力要大過外面的氣壓,所以在開啟油箱時就會有聲音的出現。其實,這時出現的聲音,問題并不大。
    Secondly, the exhaust noise usually appears in summer, because the temperature in summer is relatively high, and the gasoline will expand after heating. Because the vehicle space is fixed, the pressure of the oil and gas inside the seal will be greater than that of the outside, so there will be sound when the fuel tank is opened. As a matter of fact, the problem is not big.
    要是開啟時所出現的是吸氣聲,則表明油箱內的壓力要小于外面的壓力。出現這種情況很有可能是碳罐或電磁閥有故障了。當油箱內的壓力要小于外面的壓力,可能會出現兩種隱患:
    If there is a suction sound when opening, it indicates that the pressure in the tank is less than that outside. In this case, it is likely that there is something wrong with the carbon canister or the solenoid valve. When the pressure in the oil tank is less than the pressure outside, there may be two hidden dangers:

    一、當油箱內的壓力要小于外面的壓力,可能會引起油箱變形,要是嚴重變形的,可能會連油都加不進去。
    1、 When the pressure in the oil tank is less than the pressure outside, it may cause deformation of the tank. If it is seriously deformed, it may not even add oil.
    二、當油箱內的壓力要小于外面的壓力,和外面不通氣,那油泵就會一直往外抽,久而久之都可能會導致油泵損壞了。
    2、 When the pressure in the oil tank is less than the outside pressure, and the outside is not ventilated, the oil pump will always be pumped out, which may cause damage to the oil pump over time.
    那如何判斷這種氣體呢?要是你開啟油箱蓋時有這種的聲音,應先開兩天車后開啟一下油箱蓋;然后再開幾天車后,等到這箱油用完之后,若每次都使用這種聲音的話,那基本上就可以判斷是負壓。如果真是這樣的話,那就應該去維修了。
    How to judge the gas? If you make this noise when you open the fuel tank cap, you should first drive for two days and then open the fuel tank cap; then, after driving for a few days, when the oil tank is used up, if you use this sound every time, you can basically judge that it is negative pressure. If this is the case, it should be repaired.
