Basic knowledge about plastic fuel tanks
Abstract: The fuel tank is undoubtedly one of the most important parts of the car, and the capacity of the fuel tank also determines the one-time cruising range of the car.
The fuel tank is undoubtedly one of the most important parts of the car, and the capacity of the fuel tank also determines the one-time cruising range of the car.
The material of the fuel tank
1. The iron fuel tank is the earliest popular fuel tank. But at present, most developed countries such as Europe and the United States have gradually stopped using them, and some places have even issued regulations prohibiting the use of iron fuel tanks in automobiles; in my country, there is no hard requirement whether to use iron fuel tanks. You must know that iron fuel tanks are used in the truck field. The application rate is very high.
2. Plastic fuel tank is currently the most popular fuel tank in the world. It evolved from iron fuel tanks, and the penetration rate in most developed countries such as Europe and the United States has reached more than 90%; but in my country, plastic fuel tanks are mostly used in the car field, and the assembly cost is relatively high.
Summary: At present, in my country, the application ratio of plastic fuel tanks to iron fuel tanks is 50-50%, mainly because the iron fuel tanks of large trucks are used too much and the ratio is increased. But in general, plastic fuel tanks will be better than iron fuel tanks, but not absolute, it depends on the application scenario.
Why sometimes there is an inhalation sound when I open the plastic fuel tank?
Careful and experienced people will find that sometimes, there will be a sound of gas at the moment the plastic fuel tank cap is opened. This sound is mainly caused by the difference between the pressure inside and outside the plastic fuel tank. Under normal circumstances, the carbon canister in the plastic fuel tank has the function of balancing the internal and external air pressure; but after the carbon canister has malpractice, if the plastic fuel tank cap is also lost Pressure relief will cause pressure imbalance.
When the pressure inside the plastic fuel tank is lower than the outside pressure, there will be an inhalation sound when it is opened. This kind of phenomenon indicates that the canister or solenoid valve is malfunctioning. In addition, it is also very likely to cause the following two hidden dangers: 1. It may cause different degrees of deformation of the plastic fuel tank, and even the oil cannot be filled in; 2. There is no air flow to the outside, which will cause serious damage. Oil pump.
Editor's warm tip: It is not recommended to refuel after the fuel tank has turned on the alarm. Because in the case of low fuel consumption, intense driving will affect the operation of the fuel pump due to the vehicle's large roll; and after the fuel level warning is on, you are not sure whether you can find a gas station within the cruising range, especially when running. High speed or when in a strange city.
