Do you know what you should pay attention to when refueling your car?

1) Turn off the engine.

2) No smoking.

3) Do not use your mobile phone, leave it in the car or turn it off.

If the gasoline is too full, the temperature is high in summer, and the car itself will also produce heat, the gasoline will expand and contract, in order to prevent the fuel tank from being broken when the gasoline volume collides, there are ventilation holes on it. If the refueling is too full, the gasoline will overflow through the vents, and spontaneous combustion will occur when encountering an open flame, and the consequences are unimaginable. And the gasoline that spills through the vents will drip on the body, causing some corrosion to the body.

At the same time, overfilling of gasoline is also easy to cause the fuel tank vent to be blocked. Once the vent is blocked, the air pressure in the fuel tank will be lower than the normal pressure, resulting in poor oil supply, or even no oil supply. Filling up too much petrol will increase the weight of the car itself, which will increase fuel consumption.

Over time, gasoline will also deteriorate, leaving hidden dangers to its own safety.

When driving the vehicle, you should also pay attention to the fuel gauge indication at all times, and when the pointer shows a quarter of the fuel left, it is time to refuel. It's best not to wait for the fuel gauge light to turn on before refueling, the current car uses an electronic oil pump, which needs to be lubricated and cooled by gasoline, if you often wait for the oil lamp to be on and then refuel, the oil pump will not be well lubricated and cooled, and eventually lead to a decline in the life of the oil pump.

And if the fuel tank is empty for too long, the temperature difference between the inside and outside is large, and the inside of the fuel tank is easy to produce moisture, which will corrode the fuel tank, affect the oil quality, and increase the burden on the engine.

If you don't refuel at noon, due to thermal expansion and contraction, the volume of gasoline will increase with the increase of temperature, and when the temperature decreases, the volume of gasoline will decrease.

It should also be noted that try to choose a large gas station for refueling, and observe that if the gas station happens to park a large fuel tanker, choose not to refuel. Because if the tanker truck is just ready to unload the oil, the oil in the oil depot of the gas station has bottomed out, and a lot of impurities will be precipitated; If there are too many impurities in the gasoline just after unloading, we will add oil with a lot of impurities when we go to refuel.

Precautions. The new car should not be filled up the first time, otherwise it may cause the oil float and sensor to fail, resulting in the distortion of the fuel gauge, just like a 100-kilogram new earth jacket jumping on a 100-kilogram fat man.

I hope it will be helpful to you, practitioners from Zhanjiang Jinfu Automobile!

<> "Many cars are still fuel-fueled, even for some hybrid models, the demand for gasoline is also very large. If you usually drive a lot of mileage, you need more fuel to accompany you. So what should I pay attention to when refueling my car?

There are many requirements at gas stations, such as not using lighters to smoke, etc., but playing ** is also not allowed. Now the frequency of use of mobile phones is getting higher and higher, so Luqi gas station is also the most common mistake. Even in the car, it is not allowed.

At different gas stations, some fuel dispensers are not necessarily easy to use. Be sure to clearly inform the fueler of the type and label of the fuel you want to fill. Especially for some diesel SUVs, some refuelers don't know that if you fill the wrong gas, it will cause damage to the vehicle.

Sometimes, the staff at the gas station are busy, and they may fill up your car with gas and go to other cars. But the refueling gun, some of which do not jump the gun, will cause the gasoline to overflow. So get out of the car and check the gas gun as much as possible.

Generally speaking, it is best not to wait for the fuel to be refueled when the fuel is about to run out, mainly because the fuel pump of the EFI car is installed in the fuel tank and cooled by gasoline. Especially in summer, if the temperature is high, if the vehicle often drives at a low oil level, it is easy to cause gasoline to evaporate quickly, forming "air resistance" in the oil circuit, making the engine run unstable, and even the phenomenon of stalling and restarting is difficult.

In some small gas stations, the gasoline grade is too low, and the long-term use of low-grade gasoline will cause abnormal combustion, resulting in detonation, increased fuel consumption, cylinder knocking and insufficient power. Especially in summer, due to the high temperature, the heat is not easy to dissipate, and the oil evaporates quickly. It is very easy to create carbon deposits or clog the oil line, causing the engine to stop.

Filling up the tank will reduce the number of trips to fill up the car and may save you from making trips to the gas station. But it also has a lot of drawbacks. So what should you pay attention to when refueling, which will be more suitable for the car?

Because the oil pump is located in the oil tank, the oil pump has a high temperature when it is working continuously, and it can be effectively cooled down by immersing it in the fuel. When the oil lamp is on, it means that the oil level is lower than the oil pump, if you wait for the light to turn on every time to refuel, it will shorten the service life of the oil pump, and if the oil storage is too little or the fuel is exhausted, the oil pump may be burned. If you drive more than 30,000 kilometers, you need to be more careful, once the oil pump pumps up the sediment at the bottom of the fuel tank when the oil storage is too small, if it only blocks the oil pump or blocks the oil path, it is considered lucky.

Because there is always more or less some moisture and impurities precipitating at the bottom of the tank, these moisture and impurities will be lifted up and mixed with the fuel when unloading, if this fuel containing water and impurities is accidentally added, it will block the oil circuit and cause damage to the engine of the motor vehicle.

The new car should not be filled up all at once, otherwise it may cause the oil float and sensor to fail, resulting in the distortion of the fuel gauge, just like a new weighbridge with a load of 100 kg jumping on a 100 kg fat man. For the sake of safety, it is enough to add the oil gun to jump the gun, and it is not recommended to fill the oil to the mouth of the fuel tank. There is no need to ask the field attendant to lift the oil gun a little more after the oil gun jumps and then continue to refuel.

<><1. Choose the timing.

Refueling in the morning or evening is the most suitable. At noon, it is necessary to refuel, because the temperature is high at noon, the principle of thermal expansion and contraction, the volume of gasoline will increase with the increase of temperature, and when the temperature decreases, the volume of gasoline will decrease. Therefore, it is more cost-effective to refuel in the morning and evening than at noon.

2. Normal addition to the jump gun full will not hurt the car.

The fuel tank is sealed, and the filler port is not large. When refueling, gasoline has to enter the tank, and the air in the tank must be exhausted. Therefore, when refueling, there will be air overflow from the fuel filler, and gasoline will not flow into it easily.

So the engineers designed a ventilation device. A vent is arranged at the upper part of the fuel tank, and the air enters from the vent when refueling, and is guided to the fuel filler by the pipeline, and then the oil and gas machine of the refueling gun is not wide. And the height of this breather is exactly the upper limit of the safe volume of the tank.

Many old drivers say that the oil pump is immersed in the fuel tank, if the oil lamp is on, it means that the oil level is lower than the oil pump, and the oil pump can not be effectively cooled, which will reduce the life or even destroy.

This statement is a bit misleading on how fuel pump cooling works. The oil pump is not cooled by the oil immersed in the oil tank, but by the oil sucked into the pump to absorb heat, and as long as the oil can be fed, the cooling work will continue.
