Seabet

Maybe many car owners are when opening the fuel tank cover,I have been unscrewing for a moment,I heard the sound like Ka Cola。Generally speaking,This situation appears,It is due to the internal and external air pressure inside the fuel tank,Occasionally,It's normal,But if you refuel, you will hear,It has to be paid attention to。


Outside of the fuel tank,There is an important part called carbon can,is a device that mainly seabet loginbalances the internal and external air pressure。If the sound (abnormal air pressure is abnormal) if the oil cover is opened for a long time,It is most likely that there is a problem with carbon can,The oil tank cannot be excreted normally,Leading internal and external gas pressure imbalance,So there will be sound。


Judgment is normal or suspected of failure,Except the frequency (often occasionally),It also needs to be distinguished: whether it is discouraged or inhaled。seabet myThat shows that there are basically no big problems,Especially at high temperature in summer,Due to the excessive temperature difference inside and outside the fuel tank,The rise in gasoline temperature leads to a large pressure inside the fuel tank,It is normal to have gas leak when opening the fuel tank cover。


Converse,If you hear the sound of inhalation,It means that the pressure inside the fuel tank is less than external pressure,This situation is likely to be a carbon can or solenoid valve.,may cause these two consequences:

1. Due to too much internal pressure,It is easy to cause the fuel tank deformation,If it is severe deformation,May not even add oil,lead to unable to refuel;

2. Due to the fuel tank and the outside,Oil pump will always pump out,Over time, it may cause damage to the oil pump。


The sound of breath usually appears in summer,Because the temperature in summer is relatively high,Expansion seabet mywill occur after gasoline is heated,Because the vehicle space is fixed,Oil and gas sealed by sealed will cause pressure,The pressure inside is greater than the air pressure outside,So there will be a sound when turning on the fuel tank。Actually,The sound appeared at this time,The problem is not big。

Picture

If you hear the sound of the gasoline cover,Explain a problem with carbon can or solenoid valves,The pressure in the fuel tank is less than the pressure outside,It may cause the following two situations:


Picture


1、When the pressure in the fuel tank is less than the pressure outside,and the outside is not ventilated,Then the oil pump will continue to pump out,Over time, the oil pump may be damaged;

2、If the internal pressure of the long -term fuel tank is less than the external pressure,The fuel tank may deform,Severe possibilities may not even add gasoline。

Summary:The inside of the fuel tank must be positive pressure,It is impossible and not allowed to generate excessive negative pressure。When I heard the sound of inhalation,Old drivers must pay attention to。
