Each car has its own fuel tank. There is no specific standard for the parameter of volume, which would be adhered to by all car manufacturers. Let's see, what is the fuel capacity of different types, we define features and device data elements.

fuel tank capacity

How manufacturers calculate capacity for fuel?

It is believed that the car must have enough fuel to make it on one tank was able to drive 500 kilometers. This unwritten rule followed by many automakers. Therefore, the fuel tank capacity will be different for vehicles with high and low fuel consumption.

The average fuel tank capacity 55-70 liters of gasoline, however, due to low consumption of fuel efficient engines there is a tendency to reduction of the capacity of the fuel tank. It is logical, because a passenger car with a small displacement engine needs much less fuel to travel 500 km. in addition, the efficiency of the fuel increases at the expense of increasing the octane number and the use of different additives, which also involves the saving and reduction of tank capacity. A big jeep with a voracious engine "eat" much more fuel, hence the fuel tank it should be roomier.

the neck of the fuel tank

As for the diesel, the fuel tank of cars that consume diesel fuel, often less compared to petrol cars. This is logical, as the efficiency of diesel fuel is higher than the efficiency of gasoline. Therefore, a car with a 40 litre tank full of diesel fuel, will travel the same distance as a car with a full 50-litre tank. But it's too rough comparison.

Fuel tanks of cars of the automobile type

The Order was clear figures, you need to contact the technical parameters of vehicles. The new "Lada Vesta" the Russian concern "AVTOVAZ" is equipped with a tank capacity of 55 liters. This is quite a high figure, and the nearest competitors - "Kia Rio and Hyundai Solaris" - are equipped with tanks to 43 liters. The fuel consumption of these machines is approximately the same, which means that "Lada" will pass on the full fuel a greater distance, which is one of the benefits.

fuel tank KAMAZ

The larger the car "Volkswagen Tiguan" is equipped with a tank capacity of 58 to 64 liters (depending on specific modifications) and such a huge car like Toyota Land Cruiser, with great fuel consumption, have a 93-litre tanks.

As for the size, it's all much more complicated. Some manufacturers make rectangular tanks, the size of which approximately can be 60х40х20 see There are tanks with completely different sizes, and some manufacturers are adapting these fuel tanks so that they fit into the design. Their size cannot be described with three or four parameters.

Capacity tanks of trucks

As for trucks, the popular car KAMAZ, a fuel tank which depending on model can have different volume. The minimum capacity – 125 litres. However, due to the large consumption of fuel of KAMAZ is not able to walk long distance (but still loaded) on this tank, so the manufacturer has provided other containers that are used on this car. Thus, KAMAZ fuel tank may have a capacity of from 125 to 600 liters at step 50 or 40 liters.

 fuel tank Gazelle

Can Also be non-standard modifications on tanks 700 litres. The fact that not only the production plant manufactures fuel tanks, it can also engage third party manufacturers. In General, the market is small the probability to find the products of the plant "KAMAZ", the most common tanks from third-party manufacturers.

The Second most popular truck – the GAZelle. Despite the fact that this machine is truck, fuel tank GAZelle only holds 60 litres of petrol. And it is very inconvenient, given that the fuel consumption of the car is quite large. Therefore, when riding long distances you have to take along extra fuel cans.

Some owners of these cars change the old small tank to the new one. Third-party manufacturers produce for gazelles fuel tanks with a capacity up to 150 litres.

All of this leads to the conclusion that the fuel tank – changing, not constant, and for different cars it is different. Even two identical models can use completely different fuel tanks with different capacity.

fuel tank

Huge trucks of type SCANIA 113 and does have tanks 450-500 liters. The DAF XF can have 870 liter fuel container, and the truck MAN F90 with a large capacity is equipped with a tank for 1 260 litres. It's just incredibly large capacity, and small 45-larvae tanks, cars in the background look ridiculous.

Device fuel tank

Now that we understand how many litres the fuel tank may contain gasoline, to talk about his device. On cars it is placed in the rear, under the passengerseats. However, his close durable metal plate to deform in a collision, as well as insulate it from overheating with a special insulating strips.

Material

Tanks can be made of metal, aluminium, plastic. Aluminum tanks are used to store gasoline and diesel fuel, steel – for gas. As for plastic tanks, they have become very popular in recent times because of ease of production and molding. Due to the peculiarities of plastic quickly acquire the desired shape, manufacturers produce tanks with different structural complexities. In addition, this material is not subject to corrosion, protects against leaks due to the use of different technologies (coating the inner surface with fluorine – is one of them).

cover fuel

Filler neck fuel tank

Fill the tank through the neck, which is often located above the rear fender right or left side. Experts explain that is ideal from the point of view of safety of the location of the fuel is left, because when filling this reduces the chances of starting before the gas nozzle out of the tank. So the driver better control of the process.

Connects the neck to the tank through the pipeline, and it is located under a special cover of the neck of the fuel tank. This cap on old cars open from the outside (that is, any passerby can open it), but on modern machines the lid opens from the salon. Most commonly used mechanical method of opening by means of a cable.

Fuel line

The Supply of gasoline or diesel fuel in the engine feed system is carried out through the output fuel line. For this purpose, the fuel pump, which pumps gasoline from the tank to the power supply system of the engine. The fuel which is not consumed in the engine is returned back to the tank. Since gasoline is continuously circulated through fuel line: part of it is spent on the engine, and the second is returned.

Level Sensor

The sensor is in all tanks and is part of the fuel pump. If the fuel level decreases, the float falls below. This entails a change in the resistance of the potentiometer connected with a float. As a result, the voltage of the power supply falls, and the arrow on the instrument panel displays change. So the driver sees, how much gasoline left in the tank.

how many liters fuel tank

Ventilation

One of the important systems – ventilation. The fact that the tank must always keep the pressure equal to atmospheric, and is responsible for ventilation. Modern machines are equipped with a closed ventilation system of the tank, which prevents a drop or increase in pressure inside it. If the pressure inside the vessel decreases, it may be deformed, and the pressure increase at all can break the tank apart. Given that inside is the fuel, the realization of an effective ventilation system paying much attention.

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

When filling the tank gets extra air, which are formed pairs of gasoline. These surpluses are displaced ventilation system for special pipeline. Also the gasoline fumes may form at elevated temperature, which also increases pressure. And only the ventilation system saves the tank from full to break to pieces.

Conclusion

The vehicle Fuel tank is quite a complicated design. Despite the seeming simplicity of the device in the tank there are many different processes (evaporation, oxidation of fuel) that need to be addressed in developing these capacities. But if you compare the device of the tank with the motor, or at least with a power system, it is primitive.

Now you know what's inside the fuel tank, what is the volume of cars and trucks, and why it's so small runabouts. Against this background, it becomes clear tendency of decreasing the capacity of the tank in modern compact cars.
