The car was rotten to know that the small hole in the fuel tank actually had a big effect, and the owner didn't say it earlier!

Although many people have been driving for several years, they are not very clear about the role of some parts on the car. Some people call themselves veteran drivers, but they don't know anything about cars other than the basics. The car is composed of thousands of parts, each of which has its own unique role, everyone is more familiar with driving, but if you take out a part to ask its function, many people will be blindfolded.

Speaking of this road, I don't know if you have noticed that there will be a small hole next to the fuel tank, and its role is still very large, but many people don't understand it at all.

If the car wants to drive normally on the road, it needs to be refueled, and the car without oil seems to be a pile of scrap iron that loses its role, and there is a lot of attention to when refueling. There is a lot of information on the fuel tank cap of the car, and there is also the most suitable number of gasoline to add to the car, maybe some people are more clear about this, but after opening the fuel cap, there is an inconspicuous hole under the fuel cap, but they have never found it.

The role of this small hole in the fuel tank is very large, when the small hole is filled with air when it is not filled with oil, its function is to exhaust, if the small hole is blocked at this time, then it will lead to insufficient exhaust of the fuel tank, and it is difficult to fill the fuel tank when refueling. If it is severe, it will also lead to oil leakage in the tank. As we all know, oil leakage is very serious, once there is an open flame, it will cause spontaneous combustion of the car or **, thus threatening the safety of the driver.

This small hole communicates with the outside air, and in winter and summer there will be considerable changes in temperature, and gasoline will also change, and the small hole can balance the pressure inside and outside the tank. When there is oil in the car, the AT can make the car drive better, and if there is no oil in the car, it can also automatically absorb oil to solve the problem of the owner having no oil.

Seeing these, some netizens said that they did pay attention to this small hole when they were refueling, and at that time he thought that this small hole was which screw was dropped, in order to avoid problems, he also found a hard object to block the hole, and now he saw a cold sweat at the end, and quickly cleaned up this small hole.

Here I would like to advise you that many parts of the car have a very big role, and you must do a good job of investigation in advance when buying a car or learn more about the situation with the sales staff of the 4S store, so that you can play a better role in the use of the car. In addition, we should also regularly maintain and repair their own cars, and don't buy the car and ignore it, otherwise once there is a problem, it will be too late to regret it. Don't know if your car has this hole?

If so, clean it up.

The small holes in the fuel tank are to prevent the fuel in the fuel tank from splashing out due to oscillation, the escape of oil vapor and the entry of external dust, and the fuel tank should be capped and sealed. However, when the fuel level is reduced due to consumption, a certain vacuum will be formed in the fuel tank, so that the oil pump will lose its oil absorption capacity; In addition, when the temperature is very high, the fuel evaporates, and the oil vapor will cause excessive pressure in the tank. In both cases, it is required that the pressure difference between the inside and outside of the tank can be automatically communicated with the atmosphere.

For this purpose, there are air vents on the fuel tank cover to balance the air pressure inside and outside the fuel tank.

During use, ensure that the vent hole on the fuel tank cap is unblocked. If the vent is blocked or the fuel tank mouth is pierced with plastic sheeting when the fuel tank cap is lost, the inside of the fuel tank will form negative pressure due to the drop of fuel level when the engine is working, resulting in unstable engine operation, power drop, automatic shutdown and difficult to start in the hot engine state.

Therefore, in the process of daily maintenance of diesel generator sets, we should take the initiative to pay attention to the condition of the pores and pay more attention to whether the pores are blocked to ensure the combustion efficiency of the diesel generator set.

Nowadays, with the rapid development of economic development, more and more people have their own cars, and many people have mastered a lot of automotive professional knowledge in order to maintain their own cars, but most people have mastered all about oil tanks, modules, and car engines.

It is very likely that very few people know about the basic know-how, and there is also a lot of information reflected in the fuel tank of the car. For example, it's not too late to understand the three key pieces of information that we are going to summarize below.

The first is tire pressure.

Value, which records the standard value of the tire pressure that should be applied to the vehicle under different loads. Although this point is overlooked by many people, it is a major point, because in general, the car moves forward with the help of four tires, and at ultra-high speeds, combined with the net weight of the car itself, the tires will cause significant sliding friction with the road surface at the beginning.

In addition to the net weight of people, as well as a variety of loads, the friction between the car tires and the road surface will be higher, in this case, if the tire pressure value is too low, the tire will be flattened, which may cause hunger into a fried tire, and it will also be more fuel consumption. And if the tire pressure value is too high, it is also very likely that the tire will burst, which is very dangerous.

The second is the car fuel labeling. The gasoline that must be added to each car has a compatible model specification, if the driver accidentally forgets it, you can try to look at the fuel tank, because it is generally written on the fuel tank that you need to use cooking oil.

The model specifications, for the car, too high-end and too low-end specifications are not very good, because if the use of car gasoline is higher than the compatible type, it will be very expensive assets, naturally rich casual. If you use less than compatible car gasoline, it may damage the engine of the closed car, which you must be aware of.

The third is the drain hole. Special attention refers to this point is not what the text indicates, but is really a small round hole, its function is to avoid too much leakage and harm to the internal structure of the car, drivers must always observe whether the hole is blocked, otherwise if too much water infiltrates into the internal structure of the car fuel tank, then it is not good, once you find that there is often oil leakage outside, you can also see if the drainage hole is blocked.

This small port functions as a side-by-side check valve. For example, when you refuel, the head of the gun will hold it up and transport, and if it is not refueled, it will be tightly closed, such as when the vehicle is shaking and unbalanced, to prevent gasoline from leaking out of it. Sneak in.

The small hole under the fuel tank cap is generally an oil drain hole. If the water flows to the outside of the oil answer or stupid box cover, the water will flow to the **! It is used for ventilation, and the fuel tank cap must be ventilated, otherwise the oil will not flow or flow very slowly.

This small hole is mainly used for exhaust and is also to prevent expansion when the weather is too hot.

This is the drainage hole Chai Chang. The purpose is to drain the rainwater that flows to the fuel tank cap when it rains and when washing the car, so that there is rainwater in the part and prevents the water from soaking into the tank.

Nowadays, with the rapid development of the economy, more and more people have their own cars, many people in order to maintain their cars, but also know a lot of car knowledge, but presumably most people know about the fuel tank, engine, engine, etc. For example, the three key pieces of information we are going to take stock of below are not too late to know.

The first is the tire pressure value, which records the tire pressure value that the car should use under different loads. Although this point is ignored by many people, it is a more important point, because generally speaking, the car relies on four tires to move forward, under the high-speed movement, plus the weight of the vehicle itself, the tire will have strong friction with the ground at the beginning, plus the weight of the person, as well as various loads, the friction between the tire and the ground will be greater, in this case, if the tire pressure value is too low, it will be flattened, which may cause a puncture, and it will also consume more fuel. And if the tire pressure value is too high, it is also very dangerous.

The second is the car fuel labeling. Every car needs to add gasoline, there is a suitable model, if the owner accidentally forgets, you can try to look at the fuel tank cover, because generally on the fuel tank cover will be written on the model of the required oil, for the car, too high-end and too low-end models are not too good, because if the gasoline used is higher than the suitable type, it will be a waste of money, of course, the tyrant is arbitrary. If you use less gasoline than the compatible type, it may damage the engine, so you must be aware of this.

The third is the drain hole. It is worth noting that this point is not any text indication, but a real small hole, its role is to prevent excessive water seepage and affect the interior of the car, the owner must always observe whether the hole is blocked, otherwise if too much water seeps into the inside of the car fuel tank, it is not good, if you find that there is often oil leakage outside, you can also see if the drainage hole is blocked.

There will be a small hole in the fuel tank of all cars, this small hole is very useful, before we have not refueled the fuel tank, the fuel tank will be filled with air, and this small hole is for exhaust, if you accidentally block this small hole on the fuel tank, then you are basically not satisfied when refueling, or if the oil is not drained properly when washing the car, in addition, the volume and pressure will also change when the temperature changes, and the atmosphere needs to be communicated. This hole can also play a role in equalizing the pressure inside and outside the tank.

This small hole is for exhaust use, and if you accidentally plug this small hole in the fuel tank, then you will basically not be able to refill when refueling. This hole can also play a role in equalizing the pressure inside and outside the tank.

The fuel container on the car is a special container for storing hydraulic oil or hydraulic fluid in the hydraulic system. The fuel tank can be divided into two types: open fuel tank and closed fuel tank. The fuel tank must have a large enough volume, and the suction pipe and return pipe should be inserted below the minimum liquid level to prevent bubbles from being generated by air suction and oil return splashing; The distance between the suction pipe and the return pipe should be as far away as possible, and a partition should be set between them.

Hello, that little hole is vented.

Hello, exhaust holes, gasoline vapor cycle.

This little hole is very useful! It can be used to install fenders, and many other functions!

There will be a small hole in the fuel tank of all cars, this small hole is very useful, before we have not refueled the fuel tank, the fuel tank will be filled with air, and this small hole is for exhaust, if you accidentally block this small hole on the fuel tank, then you are basically not satisfied when refueling, or if the oil is not drained properly when washing the car, in addition, the volume and pressure will also change when the temperature changes, and the atmosphere needs to be communicated. This hole can also play a role in equalizing the pressure inside and outside the tank.

At this time, the air vent can play a role in balancing the air pressure inside and outside the fuel tank, and once the fuel tank is sucked flat, it is not just as simple as deformation. It prevents the oil pump inside the tank from pumping fuel out for the engine. This will cause us to suddenly lose power and stall at high speeds, and it will be difficult to start.

Serious fuel leaks or ** are possible. Therefore, although this vent is inconspicuous, its effect is incomparably huge.

Originally, the old-fashioned fuel tank cap was closed, and there was a valve in it, which was invisible to the naked eye in the mezzanine. The opening and closing of this valve controls the balance of air pressure inside and outside the tank. Nowadays there is a rubber tube that leads out, and we want to know if the vent is blocked, and we can feel it by blowing on it.

When the truck is used on a regular basis, especially in the summer, when the fuel tank cap is opened, there is a sound of air flowing. If it is the sound of air out, then it means that the air vent is still unobstructed, and if it is inhaled, everyone should be careful. This means that the pressure inside the tank is less than the pressure in the outside atmosphere, and the reason for this is that the vents are completely blocked or to a certain extent no longer clear.

So now you know the role of the hole!

The car drove until it was rotten to know that there was a hole next to the fuel tank, and smart people had already used it.

In fact, these holes are mainly used for ventilation, after all, if they are not ventilated, it is not good for cycling.

It may be to prevent the danger of air pressure from being generated inside the tank.

Gasoline generally cannot be burned 100%, so it is used to remove exhaust gases.

This hole is actually the exhaust hole, which is used to circulate gasoline vapor.

I think maybe the hole on his side is for heat dissipation or exhaust.

The main function may be to exhaust exhaust gases, so it is designed this way.
