There are often some fans who have asked Xiaobian something about car care. The recent Xiaobian see the problem is referred to the maintenance of the fuel tank. The car has been in service for a long time. Does the tank need to be cleaned? For this issue, Xiao Bian has to answer it today.
A recent friend of Xiao Bian went to the 4S store to do a fuel tank cleaning. When he saw the cleaning tank, he also cleaned out a bunch of incredible things: In addition to the particles, the colloidal items, the maintenance master also cleaned the tin foil from the fuel tank. And the plastic sheet .... really scared him. Particles and colloidal substances can be considered as impurities in the oil. What is the tin foil? The original was accidentally dropped when adding fuel oil.
It is very necessary to clean the car's fuel tank regularly. Although the fuel tank is semi-closed when it is refueled, it is completely closed at all other times. However, as the car ages, the use of time becomes longer, more and more sediment impurities in the fuel tank, will inevitably with the car's fuel supply system into the engine, over time will cause damage to the car. Regarding the quality of oil products, Xiao Bian wants everyone to understand. There are impurities in the oil itself, and the bottom of the fuel tanks at various gas stations have accumulated a lot of impurities for many years. If you add fuel while the tanker is sending fuel to the depot, it is bound to add some impurities. After these impurities enter the tank, they first settle at the bottom of the tank. Slowly when there are too many precipitates, it will enter the engine of the car with the fuel, causing serious wear and tear on the engine.
When is it cleaned?
The fuel tank itself is equipped with protective measures that allow it to be waterproof and keep warm. If you are idling for a long time, it may be 30,000 kilometers and you will have to clean the circuit. Or replace the filter. Otherwise, once the oil line is blocked, the pressure in the fuel tank is too high. When the car is in the process of driving, it will shake. Under the influence of high pressure, the fuel tank is very easy to crack. In severe cases, oil leakage will occur, and the fuel consumption will also increase.
How to clean?
Fuel tank cleaning is divided into two steps, internal and external.
External: Need to check the oil tank, tubing, joints and other places for signs of depression or oil leakage. Remember to check that the tank mounting screws are tight.
Internal: Open the tank port, remove the filter tank, and suck the oil out, leaving only about 30L of gasoline in the tank. Insert the cleaned plastic pipe from the filler port into the bottom of the tank, and gently blow the gasoline at the bottom of the tank to make it roll to achieve cleaning.
When cleaning, you can use a clean cloth to block the filling nozzle, and then constantly change the position and direction of the plastic pipe, try to avoid friction oil sensor. After 20 minutes of purging, gasoline was released and impurities in the gasoline flowed out together. Note that the fuel discharged from the tank should be used after 72 hours of precipitation.
