Abbas will leak oil when it is filled with oil. What happened?

1 Usually, after refueling the jump gun, the oiler will continue to refuel in the tank in order to make up an integer. In fact, this method is not very correct. The gas station is full of oil. After the first jump, the gas station staff will jump for the second time. Because the quantity is incomplete, it should be rounded off. At this time, because the fuel tank is full, it will leak oil if you jump the gun again.

Because gasoline is more volatile than water, the oil in the oil tank will change from liquid to gas when it encounters heat (sunlight, heat generated by electric gasoline pump), which will increase the pressure in the oil tank. Even if gasoline does not leak from the cover valve, the oil tank of engineering plastics will be crushed. It is not allowed to be added to the jump gun, just to leave room for the gasoline vapor after gasoline evaporation.

Let's talk about the situation of too much gas, which is also the most common problem in our daily life. If you add too much oil, it will expand and overflow due to temperature changes, which is likely to cause the danger of spontaneous combustion of the vehicle. At the same time, too much fuel will damage the carbon canister, and excess gasoline will flow into the carbon canister with fuel vapor to form damage. When the carbon canister is damaged and gasoline vapor cannot be filtered, gasoline will be introduced into the body. Because there are many harmful substances in gasoline, long-term exposure to gasoline vapor is harmful to the body and even causes cancer.

In another case, when the gas is refueled too fast, the air in it is suddenly ejected after being compressed, and when it is almost full, the flow rate decreases, and then it is added after the bubbles are slowly exhausted. If the fuel tank is not full, there will be no fuel injection.

5 Excessive refueling is harmful to vehicles. When the oil is filled too full, the volume expansion of gasoline will burst the oil tank. Therefore, when the vehicle is filled with ABA, the oil will overflow to the outside through the exhaust hole. Moreover, gasoline is particularly volatile and will burn instantly when it meets an open flame. Cause irreparable damage. Secondly, it is easy to block the ventilation hole when filled with spilled oil. Once the vent hole is blocked, negative pressure will be generated in the fuel tank, resulting in poor or even no oil supply. It may be that the engine won't catch fire just after the car is filled with oil, or it may be that the fuel tank is too full, which leads to jumping up and down at high speed. In addition, being filled with spilled oil will cause damage to automobile parts. Oil is not only harmful to the carbon canister, but also flows into the air passage along the pipeline, making the spark plug ineffective and even causing the vehicle to fail to start.
