What are the hidden features of car oil caps?

Now cars are becoming more and more popular in our lives, many friends have also bought their own private cars, of course, the mainstream cars on the market are still fuel vehicles, so we must regularly refuel our cars when we buy a car, at this time we have to mention a part of the car fuel tank leakage in the appearance, that is, the fuel tank cap, many friends feel that the fuel tank cover is dispensable, and even feel that the fuel tank cover destroys the overall beauty of the car, always ignore it, In addition to it as a cover on the fuel tank, there are actually these hidden functions that we should know in our lives, because it can bring a lot of convenience to our travel.

The first function is that we can look at a label on the inside of the fuel tank cap, these labels also record some models of our car and some precautions on it, the most important thing is that as a fuel tank cap, he will definitely record how much oil should be added to our car, although most of the cars are 92 oil and 95 oil, but there are some parts of the high-end car engine only support 95 or more gasoline we should figure out before refueling. These are the questions that allow our engines to get the most out of them.

The second function is that we can see that there is a drain on the top of the fuel tank cap, under normal circumstances, after we open the fuel tank cover, we will find that the internal oil inlet is not persistent, but the upper In fact, this is also to prevent the rain from entering the fuel tank when the car is parked outside when it rains, so a drain port is also set up in the fuel tank cover, which can facilitate the drainage of our car, if there is an emergency, the drainage hole can also eliminate the excess sewage inside the car, Let our cars be cleaner and safer.

The third and most important function is that the car fuel tank cap will be marked on the top of our tires should be used to some tire pressures and standard tire pressure range, you must know that each car, its tire pressure range is different, but this information in addition to the user guide manual, the car body will generally be marked on the fuel tank cap, because our user guide manual many car owners have never flipped through, so it is better to look directly at the fuel tank cover, this information is concise, We must look at the range of tire pressure in our car, so that we can travel more effectively. After all, the weather is getting hotter and hotter now, so the tire pressure of our car must also change somewhat, so that our car can be fuel-efficient and run energetically.

We can take a look at a label inside the fuel tank cap, these labels also record some models of our cars and some precautions on it, the most important thing is that as a fuel tank cap, he will definitely record, how much oil should be added to our car, although most of the cars are 92 oil and 95 oil, but there are some parts of the high-end car engine only support 95 or more gasoline we should figure out before refueling. These are the questions that allow our engines to get the most out of them.

There are no special functions, just the simplest functions.

It can prevent car oil leakage as well as maintain the normal operation of the car, other skills.

In addition to the role of shielding, the car oil cap actually has many other functions.

There shouldn't be too many functions, so you can block it to prevent oil leakage from the car.

There should be no special hidden features, just for better protection!

1. Fuel label Almost all cars have an obvious label on the inside of the fuel tank cap, which says the fuel label that the car can add. We all know that the engine of each car is different, the efficiency of the way to do the work is not the same, some drivers refueling is based on the mood, today add 92 marks, tomorrow may add 95 marks, high standard cars plus low standard oil will cause luxury cars to eat coarse grain and do not work, and this has a great impact on the car engine. If you don't understand, you can open the fuel tank cap, which is marked with the gasoline label that needs to be added to this car.

Second, the standard value of tire pressure In addition to the fuel label on the fuel tank cap of the car, the fuel tank cap of most cars will also indicate the air pressure value that the tire should use under different loads of the car. Of course, as the temperature changes, the air pressure value must also be adjusted, so it is necessary to keep the vehicle under a suitable air pressure condition. If the air pressure of the tire is too low, it is not only bad for the tire, but also increases fuel consumption.

If the tire pressure is too high, especially in hot weather, there is a risk of bursting. Therefore, you must pay attention to the tire pressure when driving, but now many cars have their own tire pressure monitoring devices, so we can refer to the value on the fuel cap and keep it within a reasonable range.

3. Drainage holes Don't underestimate the exhaust holes here, when it rains, the rain is easy to enter the fuel tank along the car body, if the exhaust hole is blocked, the rain is likely to flow directly into the fuel tank, and the consequence is engine damage. So usually we have to pay attention to cleaning this drainage hole, and never let this small hole be blocked.

Its function should be able to distinguish the number of oils relatively well.

It allows us to distinguish which oil should be added, such as No. 92 oil and No. 95 oil.

There's no hidden function, don't think of simple things as complicated.

After buying a car, you have to refuel if you want to drive normally. Then, after adding fuel, the fuel tank cap must be opened and closed. However, many people think that it is just a hat and has no other features.

If you think so, then you are very wrong. I believe that because you have a car, you often go to the gas station and have more contact with the employees at the gas station. Generally speaking, employees operate themselves when refueling, and the owner doesn't know much about the car's fuel tank cap, such as the car's fuel tank cap has these three hidden functions, do you know?

First, we can see that there is a fuel label on the fuel tank cap of the car. I'm sure you all know what kind of gasoline we have in our cars, and we don't just ask the staff to fill their cars with the wrong gas. But if a friend borrowed his car, he didn't bother to ask, so just open the fuel cap.

It is also reminded that gasoline should not be mixed together, and it should not be mistaken.

Second, in addition to the fuel label on the car fuel tank cap, there is also a tire inflation pressure mark. I believe everyone is familiar with tire pressure, which is related to our driving safety. Air pressure is the root of the tire.

If the air pressure is too high or too low, it will affect the service life of the tire. The fuel tank cap is marked with instructions for changes in air pressure and vehicle load, which many drivers will not notice. Especially at high speeds, under- or over-pressure can lead to punctures.

If there are more people in the car, it is likely to cause damage and death to the car. So, if you don't understand, be sure to open the fuel cap to see this instruction. If you know enough, you can greatly extend the life of your tires.

3. In addition to the above two information, there is also an oil drain hole on the car fuel tank cap. When refueling a car, there is a high chance that gasoline will spill and collect at the tank port. The function of the drain is then to drain these liquids.

After all, the accumulation of these fluids can cause some damage to the engine. The owner should also clean the drainage holes at regular times.

After reading it, everyone knows that there is so much information on the car fuel tank cap. I believe that some people are also aware of this at first, but usually don't know much about it. In fact, this information is still very important to us, such as how much fuel is added to the car, what is the tire pressure, and so on.

The fuel tank cap of the car hides several functions: one is the small hole on the fuel tank cap, which has an important drainage function, any car, after the fuel tank cap is opened, a small hole can be seen, and the function of this small hole is to drain the car fuel tank. The second is that the fuel tank cap is marked with the tire pressure of the car, which can determine the tire pressure according to the number of passengers and luggage.

For example, when there are 2 people in the car and 1 suitcase outside, the air pressure required is; When riding with 5 people and 3 suitcases, the rear tires of the car must be pressed, and the front tires must be pressed.

I found out. The car's fuel tank cap will indicate what kind of gasoline we need to fill, there will be drainage holes under the fuel tank cap, and the car tire pressure will also be displayed.

The gasoline model suitable for the car will be marked, and the vehicle will not be damaged due to indiscriminate refueling; There is a drainage hole under the fuel tank cap of the car, which can facilitate the flow of water, this place is easy to pollute, when the sewage is generated, the sewage can be discharged from this small hole in time; The fuel tank cap of the car shows what level of tire pressure the car is suitable for, the right tire pressure is helpful for the use of fuel, and the unsuitable tire pressure is easy to cause fuel consumption. As a veteran driver, I have long discovered these features. Usually refueling, tire pressure, etc., I strictly follow the function on the fuel tank cap.

I did find these features, which are the ones that can remind you the number of the fuel, and also tell you the air pressure of the tires, and also set up drain holes, and you can also open the trunk from the fuel tank cap, and you can also get the total volume of the fuel tank through the fuel tank cap, and that's all the features that the fuel tank cap hides.

<> "Automobile Fuel Tank Cap Hiding Function.

1. Fuel labeling.

The cars are different, and the gasoline used is also different, just like our mobile phones are different, and the chargers are different. Car owners probably know that if you fill in the wrong oil, the impact on the car is huge. In life, we often hear about some luxury cars with the wrong gas.

In fact, in order to avoid this situation, car companies will label the fuel on the lid of the fuel tank when producing cars.

2. Tire pressure.

In addition to the fuel mark on the fuel tank cap of the car, there is also a tire charge to celebrate the air pressure mark, I believe everyone is no stranger to the tire pressure, which is related to our driving safety. Air pressure is the root of the tire, if the air pressure is too high or too low, it will affect the life of the tire. The fuel cap is marked with a description of the air pressure and the change in the load of the car, which many drivers do not pay attention to.

Especially when running at high speeds, because the tire pressure of the car is insufficient or too high, the phenomenon of tire bursts is triggered, and if there are many people in the car, it is likely to lead to the destruction of the car and death. So if you don't understand, be sure to open the fuel cap and read this instruction. If you know enough, you can greatly extend the life of your tires.

3. an exhaust hole.

Don't underestimate the exhaust vents, which can easily slip down the body and into the fuel cap when it rains. If the exhaust hole is blocked, there is a high chance that the rainwater will flow directly into the fuel tank, and what the consequences will be, think for yourself! So be sure to develop good habits in normal times and check the exhaust holes here often.

Generally, according to different models, the way of opening is not the same, under normal circumstances, it is divided into the following three ways to open:

1. Press to open.

Generally, compact family cars are opened in this way, which is relatively simple, and can only be opened after the vehicle is started or the key is inserted and unlocked, otherwise it cannot be opened.

2. The switch in the car is turned on.

3. The key is opened.

Many old-fashioned cars use the key to unlock the fuel cap, which has a disadvantage that it is easier to steal oil.

<><1. Automobile fuel labeling.

For the fuel use of each car's engine, the manufacturer has a clear specification, we all know that if the car is added to the wrong fuel, the impact on the car engine is very large, for example, the engine with high grade fuel uses low grade fuel. In order to avoid similar situations, the manufacturer will affix a label on the fuel tank cap of each car, and the label indicates that the car is suitable for refueling. For example, if the car runs on 92 gasoline, then the label on the fuel tank cap will state:

Gasoline of grade 92 and above is applicable.

2. Tire pressure value.

The air pressure of the tires is very important for the safe driving of the car, and most cars will have a small label on the fuel tank cap, which will write the air pressure value of the tires under different coincidence conditions. Just like the figure below, if the car is carrying two people and a suitcase, then the front wheel pressure of the tires is the most suitable for the rear wheel pressure; The car seats five people and is equipped with three suitcases, in this case the front wheel pressure of the front wheels of the car is, and the rear wheel pressure is the most suitable.

3. Drainage holes.

Careful car owners can pay attention to the design of the fuel tank mouth is tilted, and many cars have a drainage hole at the fuel tank cover, this is to prevent the car fuel tank from accumulating water when it rains, the protective effect of this drainage hole is very large, the owner can regularly check the drainage hole, the sealing of the fuel tank cover is not as good as everyone wants to cover the land, there will always be rain water into the fuel tank mouth on rainy days, if the drainage hole is blocked, the rain may flow into the fuel tank, the consequences are very serious!
