Which is more reliable, plastic fuel tank or metal fuel tank?
Abstract: The fuel tank is undoubtedly one of the most important parts of the car. The capacity of the fuel tank determines the one-time cruising range of the car. So what is the material of the fuel tank and which material is better?
The fuel tank is undoubtedly one of the most important parts of the car. The capacity of the fuel tank determines the one-time cruising range of the car. So what is the material of the fuel tank and which material is better?
The material of the fuel tank
There are two materials: iron fuel tank and engineering plastic fuel tank.
There are two materials: iron fuel tank and engineering plastic fuel tank.
Metal fuel tank PK plastic fuel tank
Metal fuel tank: The traditional fuel tank is made of metal, which is complicated in process, cumbersome and pollutes the environment.
Disadvantages: Rust has been a thorny problem for a long time. Under the action of diesel oil, which is a weakly acidic corrosive medium, the internal surface of the fuel tank is easy to rust, and the rust product blocks the filter element, causing frequent engine flameouts and strong user feedback.
Advantages: Most of the iron fuel tanks are galvanized inside, and sprayed with anti-corrosion and anti-rust materials on the outside, which have good stability and are not prone to large deformation under extreme temperature. In addition, the metal fuel tank has a long service life.
Plastic fuel tank: This type of fuel tank uses a one-time injection molding method, divided into several layers, the structure is strong and durable, and has excellent impact resistance.
Disadvantages: In extreme cases, oil leakage problems may occur.
Advantages: The plastic fuel tank with strong plasticity can meet the changeable chassis; its anti-deformation ability is better, which can effectively reduce the possibility of fire after an accident; in addition, the fuel saving and anti-corrosion ability are the advantages of the plastic fuel tank.
Prospects
At present, in my country, the application ratio of plastic fuel tanks to metal fuel tanks is 50-50. The main reason is that the application of metal fuel tanks for large trucks has increased the ratio. However, in general, plastic fuel tanks will be better than metal fuel tanks, but not absolute. , Depending on the application scenario. In fact, in the final analysis, no matter what kind of fuel tank, the car that suits you is the most important thing.
