The United States invented traditional tank oil.

This knowledge can help you understand the car fuel tank.

Most car owners may care about the engine, gearbox and suspension of the car, but few people care about the fuel tank. Although the fuel tank looks unremarkable, it actually contains many secrets, which can provide a lot of help for buying, using and maintaining cars. Let's take a look today.

1. Where is the fuel tank?

The fuel tank of most models is at the rear of the car bottom, and some models are located in the middle of the car bottom, such as Angkewei. It is reasonable to say that putting the fuel tank next to the engine can save a lot of fuel transportation distance, but it is relatively safe to stay away from the engine in order to avoid hidden dangers caused by high temperature. But there is also a problem when the fuel tank is installed at the bottom, that is, it is easy to be bumped by hard objects on the ground, so we'd better choose those models with fuel tank guards when buying a car, or spray chassis armor ourselves after buying it.

2. Will the fuel tank really break down?

Really, if there are sharp hard objects on the ground, such as stones and iron blocks, which collapse to the fuel tank at high speed after being crushed by wheels, it may cause damage to them and cause fuel leakage. The early oil tanks were made of iron, which was hard but not tough enough and easy to rust, so it was unsafe. Most of the existing fuel tanks are made of multi-layer engineering plastics, which are not only lighter in weight, but also strong in corrosion resistance, sufficient in toughness and much better in safety. Don't think that iron will be reduced when it becomes plastic.

3. How much oil can the tank hold?

Generally, the fuel tank capacity of a vehicle with a displacement below 1.6L is about 40 liters, that of a vehicle with a displacement above 1.6L is about 60 liters, and that of a vehicle with a displacement above 2.0L can reach 75 liters. In addition, it is worth noting that according to the regulations, the fuel tank capacity marked in the vehicle manual should be at least 5% smaller than the actual capacity, so as to leave a safety margin. So if your instructions clearly state that you can add up to 60 liters of gasoline, but the gas station has filled you up with 65 liters, don't think that the gas station is cheating you.

4. How far can I run if the fuel tank is empty?

If it's a vacuum, it's definitely not one meter away, but the amount of oil we see on the meter is actually discounted. If the fuel tank light is on, you can run at least 50 kilometers. If the road conditions are good, some people can even drive 100 km. There is also a more extreme situation, that is, even if the fuel gauge bottoms out and the cruising range is 0, there will still be about 1-2 liters of gasoline in the fuel tank, which can drive almost 5- 10 kilometers.

5. Will the oil pump be burnt out if the oil tank is lit and it is not refueled in time?

No, it is said that the person who can burn the oil pump is either an old repairman twenty or thirty years ago or a parrot-like Che Xiaobai. The oil pump used in cars now is specially designed. As long as they can absorb oil, their pump bodies are completely immersed in oil, and there will be no overheating. When the oil can't be sucked, the car will naturally cut off the oil and stall, so there is no problem of "dry burning".

6. Will too much gas hurt the car?

See how full it is. If it is only added to the natural jump gun, there is no problem at all, which is completely within the design range of the fuel tank. If it's a jumper, round it up. If it's within 10 yuan, there's no problem, because the fuel filler has a relatively large redundant design. However, if the total amount exceeds 10 yuan, it will soon overflow the gas filling port, so you should be careful. It is possible that gasoline will flow into the carbon tank and block it, causing damage to the car.

7. Does the fuel tank need to be cleaned regularly?

No need. But pay attention to the maintenance manual. If your model needs to change the fuel filter regularly, don't forget. Try to choose a better quality fuel filter, because poor filtration will not only cause more impurities in the fuel tank, but also easily block the fuel pipeline, making the vehicle unable to start. In addition, there is often a small hole under the oil filler, so be sure to keep it clean, because it is the only way to discharge rainwater in rainy days.

8. Is it true that the fuel tank will explode in the movie?

Don't worry, don't talk about the explosion in real life, even the gasoline in the tank is difficult to ignite. The reason why the film is made like that is that the director is whimsical or just pursuing visual effects.
