Why can't the car be filled with gas?

Why can't the car be filled with gas? Seeing the old drivers popularizing "knowledge points" for everyone, as the saying goes, eating too much is not appropriate, seven points is just right, and so is refueling. It's not good to fill up with oil, it's not good to save oil until it's old, and it's not good to add too much. There are also many things about the car's fuel tank. Today, let's talk about the harm of drinking too much. I don't know. I don't know. It turns out that we usually make mistakes in many places. Whether the car tank should be filled up or not, after listening to the analysis of professionals, I realized how wrong I was before!

When the oil is filled too full, the volume contraction of gasoline will make the oil tank burst. So when the car is designed, there is an exhaust hole on it. If the oil is too full, it will overflow to the outside through the vent. Moreover, the volatility of gasoline is particularly large, and it will go out in an instant once it encounters an open flame. Form an irreparable loss.

Some people think that at the end of refueling, the refueling union shakes or loosens the valve of the oil gun by hand, so that the numbers on the tanker jump faster, but the oil has not been filled enough ... In fact, this statement is not reliable, because first of all, every oil gun at a regular gas station has to undergo strict inspection by the Bureau of Metrology, and the error is allowed to be one thousandth to three thousandths, and the oil meter is sealed. If it's private, it's scrapped. Secondly, the oiler makes settlement according to the background pump code every day, and it is impossible to steal oil in this way.

Can you judge the fuel quantity according to the quota of the fuel tank? In fact, the fuel tank is just a container in the car, not a measuring instrument, and all of us can't judge the fuel quantity according to the rated capacity of the fuel tank. Secondly, most gasoline meters in China receive fuel quantity information based on floating electronic sensors. The electronic sensor is installed on the float of the fuel tank, and the electronic signal generated by the sensor is transmitted to the fuel gauge system and displayed on the fuel gauge. This error value is very large, and the position of the oil gauge pointer can only be a reference value, which cannot accurately reflect the oil storage.

Therefore, when refueling, try not to exceed the safe capacity according to the nominal capacity of the car, so as not to cause safety hazards. If you drive in the city for a long time, there is no need to fill up the gasoline too much. It is recommended to add it to two-thirds of the fuel tank.
