What is the material of a car fuel tank?
1 Answers
Car fuel tank materials can be divided into two main categories: metal and plastic. Metal fuel tanks can be further subdivided into two types: iron and stainless steel, with no alloy fuel tanks existing. The development of fuel tank materials has evolved from early metal (iron) to later plastic, and now, there is a gradual return to metal (stainless steel) as the primary material. On the surface, this may seem like a cycle, but in reality, it represents significant advancements in metal processing technology and the necessary measures to meet increasingly stringent environmental requirements. Plastic fuel tanks have many advantages but also significant drawbacks. For example, plastic fuel tanks can never fully resolve the issue of surface oil seepage, which is a critical shortcoming in an era where environmental protection is paramount. Fuel tank maintenance includes the following steps: Drain accumulated water and sediment from the tank, and check for oil leaks at pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, ensure that the ventilation holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out while driving.
