What is the volume of the tank. How to calculate the capacity of the container of various shapes. Why is nothing more from the norm

The volume of filling gasoline can be less if liquid accumulates in the tank. Capacity options cannot be changed, but the composition of its contents will be different. If you get into the water tank, you can observe the following:

• difficulties with the vehicle in the morning;
• uneven engine operation;
• the need for longer to warm the car before launching.

Water enters the tank for various reasons. You can remove it in one way:

1. Mix with pure alcohol gasoline (from 200 to 500 milliliters), after which to pour these liquids into the tank under fuel.
2. Through a spool on the fuel ramp. This is a more complex way, as you need to merge with a hose liquid into any transparent container. To do this, supply voltage to fuel pump with a diagnostic pad.
3. Digging manually with a long and thin hose from the dropper. You will need to install a bucket or any container under the liquid into the observation pit or just below the tank level.

You can prevent water from entering the benzobak with the help of maintaining a constant fuel level in it (it is desirable to refuel "under the string"). If you need to add gasoline into a rainy or foggy day, fill the tank for fuel to 100%. This simple technique will allow you to displace the humid air from the system, which settles the condensate while driving. Later in the fall, pour into the system of clean alcohol (enough 200 milliliters) to remove the accumulated water and prevent its freezing.

How many complete liters has a fuel tank on Renault Logan? This question is asked by many potential buyers of this car, and in fact, it is not unimportant. After all, when this question is clear, you can easily calculate how much car will drive without refueling on one tank.

On the video, you can find out how to see the accurate volume of gasoline in liters in the fuel tank.

After reading this article, you will learn not only what real volume of the tank on Renault Logan, but also about what fuel consumption is 100 kilometers in Renault Logan.

A few words about the car

Guided by the Manual from the manufacturer, you can find out that the volume of the fuel tank on Renault Logan is 50 liters, but in fact it is able to accommodate a little more

This is explained by the fact that when the fuel is heated, the volume of fuel can increase, so the fuel from the gas station is always cooled.

Most motorists know that the fuel "throat" is not recommended and proceed from the rule, that from the total volume of the fuel tank take 5% of the total capacity, thereby getting 48-49 liters of valuable fuel. But sometimes, when there is no gas stations in the next 350-450 kilometers, you have to make such an exception rules. Therefore, if you fill in a 50 liter tank of 52 liters of fuel, nothing critical will happen.

Remember that the heating of the fuel occurs not only on the ambient temperature, but also from the purity of the rotor space and the duration of continuous operation.

Why is it more from the norm?

Strict number - 50,

in the passport, Renault Logan does not mean that when it exceeds this value, the fuel will turn over the edge, but only warns about its maximum allowable amount.

The absolute majority of manufacturers of foreign cars are deliberately creating a margin of free space in the gas tank. Remember that excess fuel is in the fuel line and.

Free space in the gas tank, will only benefit for the motorist. Thus, the owner of Renault Logan can count on a long trip without refueling, because the fuel will end only 450-500 kilometers of the way.

Loganovodas for trips to large distances prefer to fill the gas tank of the car "Throat", rather than take with them extra canisters. Related to the fact that the car has a high efficiency and a variety of canisters, and fuel containers become absolutely useless on the way.

What to fill in the tank?

About how to fill in you can find on the lid of the gas tank or in the operating instructions for the vehicle.

All the necessary information is indicated on the lid of the gas tank.

The official dealer adheres to its position and recommends that AI-92 refueling.

Consumption

If you believe the passport data of the car, the fuel consumption depending on the volume of the engine shows the following values:

• in the city cycle - from 9.1 to 10 liters.
• on the track - from 5.4 to 5.7 liters.
• in a mixed cycle, from 6.7 to 7.2 liters.

However, it is necessary to remember that the final fuel consumption depends on many secondary indicators, such as: cabin load, road surface quality, driving feature, air conditioning operation and various auxiliary devices. But in any case, the fuel consumption on a 1.6 liter engine will not rise above 10.5 liters per 100 kilometers of the path.

Each car does not have a certain standard according to the parameter of the volume, which all car manufacturers would adhere to. Let's figure out what the tanks of the fuel tanks of different types, we define the features and device of these items.

How manufacturers are calculated

It is believed that in the car should be enough fuel so that it can drive 500 kilometers on one refueling. This is a checked rule that many automakers are held. Consequently, the fuel tank capacity will be different for vehicles with increased and low fuel consumption.

On average, the fuel tank accommodates 55-70 liters of gasoline, however, due to the reduced fuel consumption of small-grade engines, there is a tendency to reduce the capacity of the fuel tank. It is logical, because a passenger car with a small engine working volume is needed much less fuel in order to drive 500 km. In addition, the effectiveness of the fuel itself is growing by increasing the octane number and the use of different additives, which also implies savings and decrease in the tank capacity. A large jeep with a voracious engine "Eat" much more than gasoline, therefore, and the fuel tank should be more specific.

As for the diesel engine, the fuel tank of cars consuming diesel fuel, often less compared to gasoline cars. This is logical, since the efficiency of diesel fuel is higher than the PDD of gasoline. Consequently, a car with a 40-liter tank, fully filled with diesel fuel, will drive the same distance as the machine with a complete 50-liter tank. But it is too rude comparison.

Fuel tanks of cars of passenger type

To approximately be clear the numbers, you need to refer to the technical parameters of cars. The new "Lada Vesta" of the Russian concern "AvtoVAZ" is equipped with a 55 liter tank capacity. This is a rather high indicator, and the nearest competitors are "Kia Rio" and "Hyundai Solaris" - are equipped with 43 liters tanks. The consumption of fuel of these machines is approximately the same, which means that Lada will pass at full refueling a greater distance, which is one of the advantages.

A larger car "Volkswagen Tiguan" is equipped with a 58-64 liter tank (depends on the specific modification), and such huge machines like Toyota Land Cruiser, with greater fuel consumption, have 93-liter tanks.

As for the sizes, then everything is much more complicated. Some manufacturers make rectangular tanks, the size of which can approximately be 60x40x20 cm. There are tanks with perfectly excellent sizes, and some manufacturers adapt these tanks for fuel so that they fit into the design. Their size cannot be described in three or four parameters.

Tank capacity of trucks

As for trucks, the KAMAZ machine is popular, the fuel tank, which, depending on the model, can have a different volume. The minimum capacity is 125 liters. However, due to the large fuel consumption, KAMAZ is not able to go through a large distance (and even with a cargo) on such a tank, so the manufacturer has also provided other containers that are used on this car. Thus, the KAMAZ fuel tank can have a capacity from 125 to 600 liters at a step of 50 or 40 liters.

There may also be non-standard modifications of tanks by 700 liters. The fact is that not only the manufacturer has manufactured fuel tanks, and third-party manufacturers can also be engaged. In general, the market is a small chance to find the products of the KAMAZ plant, most often there are tanks from third-party manufacturers.

The second popular cargo car is Gazelle. Despite the fact that this car is a cargo, the fuel tank of the Gazelle accommodates only 60 liters of gasoline. And it is very uncomfortable, given that the consumption of the fuel of the car is quite large. Consequently, when driving at long distances, you have to take with you additional canisters with fuel.

Some owners of these cars change the old, a small tank to the new one. Third-party manufacturers are produced for gas supplies fuel tanks with a capacity of up to 150 liters.

All this allows us to conclude that the fuel tank is a changing, not a constant value, and for various cars it is different. Even in two identical models, completely different tanks for fuel with different capacity can be used.

Huge tanks of SCANIA 113 and have tanks at all for 450-500 liters. XF can have an 870-liter fuel container, and the F90 with a large load capacity is equipped with a tank for 1,260 liters. It is just incredibly large roomy, and small 45-liters of passenger cars on their background look just ridiculous.

Fuel tank device

Now, when we are clear how many liters, the fuel tank can accommodate gasoline, you can talk about its device. On passenger cars, it is placed in the rear of the body, under passenger seats. At the same time, it is closed with a solid metal plate to avoid deformation in a collision, as well as isolate from overheating using special heat insulating gaskets.

Material

Tanks can be made of metal, aluminum, plastics. Aluminum containers are used to store diesel and gasoline fuel, steel - for gas. As for plastic tanks, they became very popular recently because of the simplicity of production and molding. Due to the peculiarities of plastics quickly acquire the necessary form, manufacturers create tanks of different constructive difficulties. In addition, this material is not subject to corrosion, protects well from leaks through the use of different technologies (the coating of the inner surface with fluorine is one of them).

Fuel tank

Fill the tank through the neck, which is most often over the rear wing of the right or left side. Experts explain that from the point of view of the safety of the neck of the fuel tank is the left side, because when refueling it reduces the chances of touching before the refueling gun is removed from the tank. So the driver better controls the process.

A neck with a tank through the pipeline is connected, and it is located under a special lid of the fuel tank. This cover on old cars opens from the outside (that is, any passerby can open it), however, on modern machines, the lid opens from the cabin. Most often using a mechanical opening method using a cable.

Fuel line

The supply of gasoline or diesel fuel into the power supply system is carried out through the output fuel line. Also for this, the fuel pump is used, which shakes gasoline from the tank into the engine power system. Fuel, which did not consume the engine, returns back to the tank. So gasoline is constantly circulating on the fuel line: part is spent on the engine operation, and the second - returns back.

Level control sensor

This sensor is in all tanks and is part of the fuel pump. If the gasoline level decreases, the float is lowered below. This entails a change in the resistance of the potentiometer associated with the float. As a result, the voltage in the power grid drops, and the arrow on the dashboard displays the change. So the driver sees how much gasoline remains in the tank.

Ventilation

One of the important systems is ventilation. The fact is that in the tank you should always maintain a pressure equal to the atmospheric, and the ventilation is responsible for it. Modern machines are equipped with a closed tank ventilation system, which prevents drop or pressure growth inside it. If the pressure inside the container drops, it can be deformed, and the pressure increase can generally break the tank on the part. Given that inside is fuel, the implementation of an effective ventilation system pays a lot of attention.

When fuel leaves the tank, the pressure in it drops, resulting in a vacuum. Thanks to the ventilation system, this effect is eliminated: the safety valve starts inside the air. This valve is located at the cap covers, and it can pass the air in only one direction.

When refueling into the tank, there is an excess air, which is why gasoline pairs are formed. These excess are displaced by the ventilation system using a special pipeline. Also, gasoline couples can also be formed at elevated temperature, which also entails the increase in pressure. And only the ventilation system saves the tank from its full break to pieces.

Conclusion

The car's fuel tank is a rather complicated design. Despite the seeming simplicity of the device, many different processes arise in the tank (evaporation, oxidation of fuel), which must be provided when developing these containers. But if you compare a tank device with a motor or at least with a power system, it will seem primitive.

Now you know how the fuel tank is arranged, what is its volume in passenger and trucks, as well as why he is so small in small-caps. Against the background of all this, the tendency to reduce tank capacity in modern

We decided to spend this experiment due to periodic complaints of car owners at gas stations, which allegedly do not fuel fuel to the tank and write in social networks, which fastened more than the volume of the tank at the dressing station.

The rationale for this is the fill to the almost empty tank of the larger fuel, which is indicated in the car operating manual.

We deepened in the construction of cars and found technological prerequisites explaining different real and documentary (in TTX cars) the volume of the fuel tank. Now we decided to confirm our arguments and went with five different cars on the AZK of one of the major fuel market operators.

Two cars with diesel engines participated in the test - Citroen Grand C4 Picasso and Renault Duster and three gasoline cars - Volkswagen Bora, Skoda Octavia A5 and Ford Mondeo. All five cars came to the place of experiment on the minimum fuel residue in the tank.

Preparation for test

Before starting the refueling, we asked for AZK employees to check the accuracy of the filling column. To do this, at all refills there are a special 20-liter dimensional container with high-precision calf, which makes it possible to determine the belling or overflow with an accuracy of 20 ml.

After wetting the dimensional capacity (mandatory procedure), 20 liters of fuel were poured into it. The little worker confirmed that the column pours exactly, after which we began to fill our cars.

Result refueling

The main condition for refueling the aforementioned cars was filling fuel to the tank for the sickness of the throat, i.e. We have already seen that fuel - under the top of the neck. Looking in advance, we note that in fact there are more fuels in the tanks of all 5 cars, rather than in TTX (in one case - by as much as 17 l!).

First refrain Citroit Grand C4 Picasso. With a 55-liter tank (in TTX) and the residual one division of the electronic fuel level sensor in the tank was flooded with 51 liters of diesel fuel. Excess - 2-4 l.

Renault Duster. In its almost empty tank, 62 liters of fuel at the factory data is only 50 liters. Excess - 15-17 * l.

In a car VW Bora. Filled a little more than 52 liters of gasoline under 55 liter factory data. Taking into account the residue, the TTX can reach at 3-5 * l.

Real volume of tank Skoda Octavia A5. Significantly exceeded the data claimed in TTX. It was poured into it 62 liters at a rate of 55 liters. Excess - 12-14 * l

In a 70-liter tank Ford Mondeo. With a residual mileage, almost 71 liters of gasoline placed 26 km. Those. Real excess volume is 8-9 * l.

The results of this test confirmed our theoretical conclusions: the real volume of the fuel tank differs from the specified automaker for significant limits ( from one to 10 or more liters).

So the drivers should keep in mind: if you flooded a few liters at the dressing, which you expected, this is not a reason for the scandal. This is most likely the feature of your fuel tank.

* Taking into account unaccounted 4-5 liters of fuel below the floating gas tank

" It seems that the fuel tank is filled with more of its nominal capacity !!! "" never had this !!! "

Each driver, most likely, passed through such an experience. Especially when refilling the car for a full tank, some drivers sometimes doubt about the necessary amount of fuel. Especially when the amount of fuel remaining fuel and filled fuel exceeds the fuel tank capacity, officially specified by automakers. However, if such a difference is only 5-10 liters, it is natural. Since the tank was originally developed more than the rated capacity of the fuel tank specified in the user manual.

Consequently, when the above situation occurs, there is no need to get lost, you just need Check the actual difference from the nominal container.

1. Official fuel tank capacity (nominal capacity)

① "Rated capacity" of passenger cars is designed to drive about * 600 km at a speed of 80-100 km / h on motorways. The nominal capacity is designed to take into account the efficiency of fuel and body weight of the car, so it varies depending on the car model and the volume of the engine.

* About 600 km is taken from the settlement of the ride, provided that the driver drives 5-6 hours a day at a speed of 100 km without physical fatigue (based on 1 refueling per day).

② Why can the car ride another 50-60 km, even when the indicator fuel light is burning?

The indicator light was designed With backup bandwidth so that the driver can get to the next service area (filling) (average distance between service areas about 50-60 km) on the high-speed track, about 10% of the fuel tank capacity.

2. Why is the actual capacity greater than the nominal container?

If nominal The power of the fuel tank 65ℓ, then its actual container is about 75ℓ. Since in the manufacture of the fuel tank, the car manufacturer took into account the loose container, 10-15% of the nominal container. The reason for this is as follows:

② is designed to prevent the exit of volatile organic compounds (VOC. ) In the event of an increase in the volume caused by an increase in air temperature. If the fuel tank is filled to full, there is a danger that under the influence of increasing the internal temperature and accordingly internal pressure, the fuel can flow out.

② Tax backup place in the tank is left to prevent fuel leakage when the car is parked at an inclined place with full tank. This is called "Backup Capacity to Enlarge"
