What are the types of car fuel tanks? What are the types of fuel tanks for large trucks?

The volume of the fuel tank determines the driving range, and for two cars with exactly the same engine, the larger the tank, the farther it goes.

Generally, drivers know how much fuel the fuel tank of the vehicle they are driving, which is nothing more than from two aspects, one is the fuel tank volume calibrated by the vehicle instruction manual, and the other is the actual refueling experience. Many drivers have the experience that the fuel tank capacity on the instruction manual is smaller than the actual amount of fuel.

According to automotive experts, the reason for such an error is that the fuel tank volume calibrated by the automobile manufacturer is the volume from the bottom of the fuel tank to the safety boundary, and there is still a certain space from the safety boundary to the fuel tank mouth, which is to ensure that the oil in the fuel tank expands when the temperature becomes high, and does not overflow the safe space of the fuel tank. If the oil is added to the tank port during the refueling process, the actual refueling volume will be larger than the fuel tank volume calibrated in the manual. Sedimentation, rust, deformation and other reasons in the fuel tank will affect the capacity of the fuel tank.

Car owners usually judge the fuel tank capacity based on the warning light of their car's fuel gauge, which is not accurate. Generally speaking, due to the influence of various factors such as road conditions and driving conditions, the remaining capacity of the fuel tank is not exactly the same after each warning light flashes. For example, when the liquid level in the fuel tank is close to the alarm point, the vehicle will be driven at high speed, turning, going up and down slopes, emergency braking, strong vibration, etc., which will cause the alarm light to flash; At the same time, the mileage and fuel consumption are different depending on the road conditions.

Relatively crowded and slow, braking and starting frequently, fuel consumption is relatively more. The fuel tank capacity can only be roughly judged according to the warning light, and it is not the only criterion.

Fuel tank volume (L) refers to the size of the fuel tank volume to measure the capacity of a car to carry fuel, the fuel tank volume determines the mileage, for two cars with the same engine, the larger the fuel tank, the farther it goes.

The size of the tank is directly related to the fuel consumption of the car, generally a tank of fuel can travel more than 500 kilometers, such as 100 kilometers of 10 liters of car, the fuel tank volume is about 60 liters!

The fuel tank volume of each model is different, and the fuel tank volume of different brands of similar models is also different, because there is no national standard.

However, the general car manufacturers follow a rule, that is, the full fuel volume of the fuel tank generally supports about 600 kilometers, not less than 500 kilometers.

Automobile fuel tank safety material points; Iron fuel tank, aluminum alloy fuel tank, with the application and development of various new materials, the anti-rust problem of iron fuel tank has become the biggest problem of fuel tank quality. Especially in today's focus on environmental protection.

Automobile fuel tank safety material points; Iron fuel tank, aluminum alloy fuel tank,

The fuel tank can be divided into two types: open fuel tank and closed fuel tank.

Open fuel tank, the liquid level in the tank communicates with the atmosphere, and an air filter is installed on the fuel tank cap.

The open fuel tank has a simple structure, easy installation and maintenance, and the hydraulic system generally adopts this form. The closed oil tank is generally used for pressure oil tank, which is filled with inert gas at a certain pressure, and the filling pressure can reach 5MPa.

If it is divided according to the shape of the fuel tank, it can also be divided into rectangular fuel tank and round tank fuel tank. The rectangular fuel tank is easy to manufacture, and the hydraulic devices are easy to be placed on the box, so it is widely used; The round tank tank has high strength, light weight and easy to clean, but it is difficult to manufacture and occupies a large space, so it is often used in large metallurgical equipment.

In addition, it can be divided into five types:

3. The outer cover plate is equipped with a cable-type locking mechanism, which can only be opened when operating in the cab at the bottom left of the dashboard.

4. The outer cover plate is equipped with an electronic locking mechanism, and on the driver's left side door, the outer cover plate of the fuel tank is opened by pressing lightly, and the fuel tank cover is not locked. In addition, there is a kind of fuel tank outer cover plate is synchronized with the locking mechanism of the car door, the fuel tank outer cover plate is also locked while locking the door, and the fuel tank outer cover plate is also unlocked when the door is unlocked, but the cover plate will not bounce up and needs to gently press the left side with a finger to bounce up, and the fuel tank cover does not have a lock. The above does not include vans.

Generally speaking, the fuel tank of a small truck is about 60 liters, the fuel tank of a large truck is about 140 liters, and the fuel tank of a large trailer is about 200 liters. Depending on the model, the capacity of the truck's fuel tank will vary, and some models have additional auxiliary fuel tanks to increase the car's range.

That's all for me.

Generally, there are two kinds of fuel tanks that we are more common: one is plastic, the other is metal, and all the materials can be divided into iron, aluminum alloy and stainless steel.

The more common types of large truck fuel tanks are, plastic fuel tanks, iron fuel tanks, stainless steel fuel tanks, and aluminum alloy fuel tanks, which are all more common types on the market.

There are many different types, and the capacity of the fuel tank is determined according to the displacement of the car, there are 40 50 liters, 70 liters, and then 100 liters.

<> What is the difference between a car's fuel tank on the "left" and on the "right"? After reading the knowledge!

With the development of society, the development of the automobile industry is also very rapid, many people have bought their favorite cars, and after buying a car, they will need a lot of expenses in the future, and the biggest expense is to refuel the car. In life, we often add fuel to the car, because if there is no gasoline or diesel, the car still can't go, although there are now a lot of new energy cars, such as electric vehicles, hybrid electric vehicles, etc., but now it is still the mainstream of gasoline and diesel cars, I don't know if you have found a problem, that is, some of the fuel tanks of domestic cars are on the left, some are on the right, so what is the difference between the two?

First of all, we all know that the fuel tank is at the rear of the car, this is because the engine is in the front of the car, as well as the influence of the suspension structure and transmission system, in order to achieve the balance of the car, the fuel tank is at the rear of the car. This setting makes the car more stable and safer during driving.

First of all, we have to understand the driving habits at home and abroad, under normal circumstances, the fuel tank of domestic cars is on the right side, because our vehicles are driven on the right. In countries that drive on the right hand in Germany and Sweden, the tank port is generally on the right side for the convenience of refueling, but in countries that drive on the left such as Japan, the tank port is on the left side, which is also directly reflected in the cars produced in these countries.

However, owners who have understood should know that Korean cars also drive on the right, but the fuel tank of their car is set on the left, this is because at the beginning Korean cars were imitated by Japanese cars, so the setting of the fuel tank is the same as that of Japanese cars, plus the entire body model is already ready-made, if it is very cost-consuming to change the model, in order to save costs, just change the cockpit, the position of the fuel tank has not changed. Still on the left.

Of course, some cars will also be feasted according to the design of the car, for example, for convenience, the driver's seat of the car is on the left, and the car fuel filling cover will also be arranged on the left. In some countries, the driver's seat is on the right, and the car fuel cap will also be arranged on the right, which is also designed for the convenience of using the car. Another theory is to balance the counterweight of the whole vehicle, in order to balance with the driver's weight, so different sides are arranged.

When there is only one driver, the weight of the car is concentrated on the left side of the car, which can be dangerous when turning.

The gasoline tank is mainly composed of the box, the gasoline tank cover, the oil level indication sensor, the gasoline tank bracket, and the oil drain screw plug book. Its function is to store gasoline, usually arranged on the side of the frame away from the engine or at the rear of the body, to reduce the risk of fire, and to improve the stability of the car, its installation position is generally low. The capacity of the gas tank depends on the size of the vehicle and the engine displacement.

Ordinary gasoline tanks are welded with thin steel plate stamping parts. The fuel tank cap is used to prevent the splashing of gasoline and reduce the volatilization of gasoline, usually the fuel tank cap is designed to be claw type and clamped around the perimeter of the gasoline tank mouth with the rubber gasket pressed by the corrugated leaf spring to ensure sealing, and some caps are also designed with a locking device to prevent falling off or loss. In order to ensure the balance of the fuel tank or the internal air pressure, the air valve and steam valve are designed on the fuel tank cover.

When the oil level in the gasoline tank drops and the pressure is lower than a certain value, the air valve opens to make the air enter the gasoline tank to ensure that there is no vacuum in the gasoline tank and avoid damage caused by the difference between internal and external air pressure. The steam valve is pressed with a stiffer spring and only opens when the temperature in the gasoline tank is too high and the pressure exceeds the specified value, so it is beneficial to reduce the volatilization of gasoline vapor in the gasoline tank.

It is used to store the fuel required in the fuel system.

1. At present, the automobile fuel tank on the market is mainly made of metal and resin bridge judges. Relatively speaking, resin materials are more widely used, gradually replacing metal materials.

2. The resin fuel tank is a multi-layer composite material, and the cost will be higher than that of metal. However, because the advantages of resin materials are more prominent, metal fuel tanks are gradually replaced.

3. The resin fuel tank will not rust and is more corrosion-resistant. Most of the metal fuel tanks are mainly made of iron, and iron is naturally easy to rust, and the corrosion resistance is not as good as that of resin materials.

The materials of automobile fuel tanks can be divided into two categories, one is metal materials, and the other is plastic fuel tanks; Metal tanks can also be subdivided into two categories, one is iron and the other is stainless steel, and there is no alloy tank. I was a little puzzled to see many friends mention alloy fuel tanks. Stainless steel is enough to solve the problem.

Why alloys? So now the mainstream of metal fuel tanks is stainless steel!

The material development of fuel tanks, from the early metal (iron stupidity) to the later plastic, is now gradually reverting to metal (stainless steel). On the surface, it may seem like a reincarnation, but in fact it represents a significant improvement in metalworking technology and the means that have to be taken to meet stricter environmental requirements. Plastic fuel tanks have many advantages, but there are also many disadvantages, such as plastic fuel tanks, which can never solve the problem of oil leakage on the surface.

In the era of environmental protection, plastic fuel tanks have fatal drawbacks!

Who is better plastic tank or metal tank?

I vaguely remember that a few years ago, many friends despised metal fuel tanks, and some ** specialized Lu Hu used magnets to verify that a car was a metal fuel tank, and then defined low-end and low-cost? In fact, this approach is logically problematic. Is the fuel tank a low-end low-end low-cost metal material?

Then some SUV tailgates are plastic, not metal. Why are they low-end and low-cost? In fact, the metal fuel tank is not low-end, and the cost is not low.

Even under certain conditions, metal tanks are much safer than plastic tanks!

Why is there a period of time when there are fewer and fewer metal fuel tanks? The key is not that the metal tank is bad, but that the metal processing technology cannot keep up. As you can see in the picture above, this is a fuel tank with a strange shape and complex structure.

Therefore, there was no way to do this for the processing technology of many years ago, so metal oil tanks have become increasingly rare for a long time in the past; Nowadays, with the advent of laser welding, ion welding and other processes, it is possible to process special-shaped metal oil tanks, so there are more and more metal oil tanks now. Metal tanks don't mean the low end, and their processing is much more complicated than plastic, because nowadays in order to save empty rooms, fuel tanks are oddly shaped!

However, once the plastic tank is formed, the material cost and processing cost are easily controlled. For a long time in the past, plastic fuel tanks were the mainstream, so a higher-end main method of plastic fuel tanks was formed. In fact, metal fuel tanks are more ideal.

Plastic fuel tanks can't solve the problem of oil leakage. Once heated, the plastic tank will soften or even melt. For example, after the vehicle is burned after a collision, the metal fuel tank is not afraid of high temperature baking, while the plastic fuel tank is easy to change and even damage at high temperatures, which will eventually lead to gasoline leakage and deflagration.

So now the plastic fuel tank is gradually decreasing, and the metal tank is gradually returning to the mainstream!
