Nowadays, the quality of gasoline is both good and bad. After a period of time, there are inevitably various impurities in the fuel tank, which makes the filter in the fuel supply system unable to eat up gradually. There will be more and more precipitated impurities in the fuel tank. With the fuel supply system in the car entering the engine, the automobile will be damaged in a long time. The following with Jinan Benz car repair small series to see how to clean the fuel tank!
1. Why clean the tank?
Although the fuel tank is semi closed during refueling, it is fully closed at other times. However, with the increase of the age of the car, the use time is longer, and there will be more and more precipitated impurities in the fuel tank. There will also be impurities in the oil itself, and a lot of impurities will accumulate at the bottom of the oil depot of each gas station for a long time. After entering the tank, these impurities first precipitate to the bottom of the tank. When the sediment is too much slowly, it will also enter the car engine with the fuel, which will cause serious wear to the automobile engine.
2. When should I clean it?
Jinan Benz car maintenance tells you that the fuel tank itself is also taken protective measures, waterproof and heat preservation. If you drive at idle speed for a long time, maybe at 30000 km, you need to clean the oil way of the car. Or change the filter. Otherwise, once the oil path is blocked, the air pressure in the oil tank is too high. In the process of driving the car, there will also be a swing situation. Under high pressure, the oil tank is easy to crack. When it is more serious, there will be oil leakage, and the fuel consumption will become very high!
3. How to clean?
Tank cleaning is divided into two steps, internal and external.
External: clean and check the outside of the oil tank, check whether the oil tank, oil pipe and joint are concave and leaking, and tighten the fixing bolts of the oil tank bracket. If dents and leaks are found, the damaged parts should be removed for repair.
Inside: open the port of the fuel tank, take out the filter cartridge, suck out some fuel in the fuel tank, and there is about 30L of fuel left in the tank.
Insert the cleaned compressed air pipe (plastic pipe as far as possible) into the bottom of the fuel tank from the nozzle of the fuel filling pipe, and blow the fuel at the bottom of the fuel tank with air pressure to make it churn and clean. When cleaning, use a clean cloth block to slightly block the oil filling pipe mouth inserted into the oil pipe, and constantly change the position and direction of the lower end of the gas pipe.
After 20 minutes of purging, drain the fuel in the tank immediately, so that the impurities suspended in the oil flow out with the fuel. If the fuel is dirty, clean the tank again in the above way.
Jinan Benz car maintenance tells you to replace and tighten the drain plug. Clean the filter cartridge of the oil filling pipe orifice and install it into the filler pipe. Add clean fuel to the tank, cover the tank cap and wipe the outside of the tank clean. Then it should be noted that the fuel discharged from the tank should be precipitated for 72 hours before use.
