What do you need to pay attention to when filling up your car s fuel tank?

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!

This to nothing Refueling don't fill up too much I hope you can be satisfied I wish you a happy life [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Nowadays, cars have automatic locking systems, as long as the car is locked, the fuel tank is locked at the same time. So new cars don't have to worry about being stolen. In addition, novices should first pay attention to safety issues when refueling, fire prevention must be carried out when refueling, and smoking is prohibited at gas stations.

In addition, when the new car is refueled for the first time, remember to fill it up, otherwise, it will cause oil floatation and sensor failure, so that the fuel gauge will display a large error. The safest way to refuel a new car for the first time is to refuel until the gun jumps. There is no need to fill up an old car.

Just over half of the tank. First of all, because there are too many traffic lights and zebra crossings in the city, it is basically a walk, a stop, and there is no need to fill up. In addition, if the fuel is too full, the car will become heavier as a whole, so the fuel consumption will increase.

1. Novices should pay attention to adding No. 95 gasoline as much as possible: First of all, the difference between No. 95 and No. 92 gasoline is not the difference in purity, but the difference in octane number content. Octane can cause deflagration, and No. 92 gasoline has a high octane number.

Although it is cheap, long-term use will definitely have an impact on the engine, so try not to be greedy for 92 gasoline.

2. Novices should pay attention to avoid refueling immediately after unloading: because after unloading, all the impurities in the refueling tank float up, and if you add gasoline at this time, all the impurities will run into the fuel tank. The correct way is to change to a gas station or wait for the impurities to settle after a period of time before refueling.

3. Novices should learn to refuel by themselves: because many refuelers are not honest, they always add gasoline to stop and stop, and once they are stuck, the gasoline will impact the fuel gauge once. In order to prevent being pitted, pay close attention to the oiler or directly learn to use the fuel gun and refuel yourself.

Fuel tank collision will appear in the first situation, the oil will leak out of the fuel tank if it rolls over, the fuel tank will automatically jump after it is full, when refueling, it is not possible to be careless when smelling gasoline, pay attention to the situation that the fuel gauge does not move, these aspects of cold knowledge must be understood. Do not add too full, pay attention to the shape of the fuel tank, arrange auto parts reasonably, pay attention to the horizontal direction of the lift, understand the refueling of the fuel tank, and pay attention to the problem of refueling.

The first point of the car fuel tank must pay attention to the timely replacement of oil, the second point should pay attention to regular maintenance, the third point of the fuel tank should not have impurities, the fourth point novice should pay attention to is to clean up some garbage items in the mailbox in time, otherwise the car will break down.

The shape of the fuel tank is irregular, basically the upper part is wider, and the lower half is narrower;

The gasoline volume of the upper and lower parts of the fuel tank is different, usually the upper part of the oil is more, and the narrower part of the lower part of the gasoline is less, which is just after filling the oil, the reason why the gasoline level in the tank drops slowly, and after the second half, there is the illusion of increased fuel consumption;

Because the volume of the fuel tank becomes smaller, the gasoline stock is not high, and the fuel gauge will respond quickly.

Generally, the upper part is more resistant to burning than the lower half, the fuel tank cover of the car will produce suction after opening, and the fuel gauge light will not affect the oil pump after it is lit.

For a car, the fuel tank of the car is a very important part, and many friends who drive do not know that there is a lot of cold knowledge in the mailbox, for example, why can you add a little more after each fuel tank is full, this is because the capacity of the rated fuel tank of the vehicle is not the real space size of the car, for example, our own car fuel tank is 75 liters, in fact, it can actually hold about 79 liters to 83 liters of gasoline, and some people are more curious, why will the fuel tank automatically jump after it is full, This is because when refueling, when the gasoline enters the fuel tank of our vehicle, the air inside the fuel tank will be squeezed out, and when the fuel tank is full, the gasoline will block the snorkel in the car, and the gasoline will not flow smoothly into the fuel tank, so it will flood the refueling gun port and cause automatic jumping. However, we need to remind everyone that we should never fill up too much when refueling, or there is too little oil left in the tank, which is likely to cause the oil float to get stuck.

1. Where is the fuel tank of the vehicle generally located? In fact, most of the mailboxes are under the rear seat of the car, such a design is to facilitate the replacement of the oil pump or when there are some problems with the fuel tank, you can check the condition of the fuel tank at any time, because the fuel tank is in the rear row, and the seat can be seen as long as the seat is disassembled, so when we sit in the car, if we smell a serious gasoline smell in the back row, we must pay attention to it, we should lift the seat to see if there is a problem with our fuel tank.

In fact, after the fuel gauge light is on, it will not cause great damage to the oil pump, because the gasoline pump is pumped into the gasoline through the axial flow to dissipate heat at the same time, as long as there is gasoline in the car, then the gasoline pump will not have a problem in dissipating heat when the oil can be pumped, but it should be noted that if the oil in the car tank is not ready to be left, we must pay attention to the timely flameout, Don't power the car at this time.

When refueling gasoline, don't add too full, generally add to the jump gun after you can rush the wheel, it is not recommended to make up the round, even if you round it up, you can make it up to the yuan. Don't make too much of it. The general car fuel tank will exceed the nominal fuel tank design, for example, the general 45L fuel tank can be filled with more than 50L of gasoline.

So, don't always think that the gas station is pheating you when you are refueling. When it comes to people, some unruly gas stations may indeed do this. When refueling independently, you must pay attention to releasing the pressure of the mailbox, but do not leave the fuel tank open for too long, because the fuel tank contains a large amount of gasoline vapor, which is also a valuable resource, and it is believed that if the vapor is wasted, then the new gasoline will volatilize to fill the fuel tank, which is an indirect waste.

Don't fill it up when refueling, because there is no air hole on the top of the fuel tank, it is easy to block, and if it is too full, it will also be out of the situation that Kaiwang potato is now spraying fuel, sometimes the flow meter will not move, probably because the oil float is stuck, and then the fuel tank stare cover is electric, and the vehicle needs to be unlocked to automatically pop up.

Most of the fuel tank is a virtual punch is the upper part is relatively wide, the lower part is narrower, and the shape is irregular, and the difference in the design of the fuel tank will also have some safety margin settings. The filler can be properly vented so that the effective pressure can be controlled without wasting oil. Pay attention to the quality of oil sales.

When refueling the car fuel tank, do not make a fuss to refuel, but to refuel, so that it can play a better role, and the delay can also avoid the problem of liquid socks in the car's fuel tank, and when refueling in the later stage, we must pay attention to the quality of the oil.

When you go to the gas station, turn off the engine, don't use an open flame, don't smoke, don't pick up **. Refueling at a gas station is something that many car owners do. It is forbidden to use open flames at gas stations, and it is also forbidden to play ** in Layuan, otherwise it is very dangerous.

Some car owners often go to some small gas stations with poor fuel quality in order to be cheap. If they use this low-quality gasoline for a long time, it will lead to an increase in carbon deposition in the engine and affect the normal operation of the engine.

Carbon deposits generally appear in the intake, throttle, valve, combustion chamber and other parts.

If carbon deposits are in the combustion chamber, it will lead to an increase in the compression ratio of the combustion chamber, resulting in engine knocking, a decrease in engine power and an increase in fuel consumption.

It is recommended that riders regularly clean up carbon deposits for their car engines, and the walnut sand cleaning method is a more effective way to clean up carbon deposits.

Some repair shops will use the bottle hanging method to remove the carbon deposit. This method is not very effective and is not recommended for riders.

What is the cause of the shaking of the car while driving?

1. Steering machine problem:

1) Excessive wear of the steering rod ball joint: because it is active, it will wear out after a long time, and there will be a slight angle inaccuracy when cornering, so there will be tire shaking and blurred steering at high speed;

2) Steering gear fixed rubber bushing wear: This kind of problem is relatively rare and easy to fix, and can be seen with only the naked eye, but once it is worn, the steering wheel will tremble when driving.

2.Tire Problems:

1) Rim deformation: Generally, the violent impact of external forces will cause rim deformation, for some cars with flat tires, it is more likely to have problems, and the wheel hub needs to be replaced;

2) Wheel sensitive tire imbalance: Some car owners do not carry out tire dynamic balancing after disassembling and assembling tires, which will cause high-speed steering wheel shaking. Generally, going to a tire shop to carry out tire dynamic balancing can solve the problem;

3) Tire deformation: Carefully touch the four tire tread sections of the car with your hands. If you find that the tire tread is uneven, the bridge or a tire has a relatively abrupt "bulge", it is a tire deformation. Sometimes a tire punctured by a nail can also cause an abnormal sound and heel shaking.

3.Deformation of the propeller shaft:

1) When the car collides with or scratches hard objects, such as curbs, stones, etc. , it is damaged;

2) The transmission shaft screw is seriously loose or lost, resulting in misalignment;

3) The installation angle of the flange fork and telescopic fork is incorrect, and the waist beam bearing and shock absorption skirt plate of the multi-section transmission shaft are damaged;

4) When the transmission oil pump is twisted and deformed, the feeling of shaking when the car accelerates is particularly obvious.

<> "Try not to wait for the oil lamp to come on before refueling. 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.

Try to avoid refueling at a gas station when it has just finished unloading. Because there is always 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, and if the wild servant accidentally adds this fuel containing water and impurities, it will block the oil circuit and cause damage to the engine of the motor vehicle.

The new car should not be filled up at once 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 new weighbridge with a load of 100 kg jumping on a 100 kg fat man. In order to keep your eyes open for safety, you can add the oil gun and jump the gun, and it is not advisable to fill the oil to the mouth of the fuel tank. There is no need for the refueler to lift the refueling gun a little bit after the refueling gun jumps and then continue to refuel.
