Both metal fuel tank and plastic fuel tank can ensure safety
recently, some consumers have raised questions about whether the material of fuel tank affects vehicle safety. What is the difference between metal fuel tank and plastic fuel tank? With questions, I interviewed several experts in the automotive industry. How to achieve high extensibility while significantly improving sensitivity is still a challenge at present. I found that metal fuel tanks and plastic fuel tanks are widely used all over the world, which can ensure safe use
national standard for fuel tank safety
in terms of motor vehicle fuel tank standards, China has issued the standard for the use of vehicle fuel tanks (GB), which stipulates that motor vehicle products produced by automotive enterprises need to pass the tightness test of fuel tank cover, safety valve opening pressure test, vibration durability test, fuel tank pressure resistance and other tests. Both metal fuel tanks and plastic fuel tanks need to be strictly tested according to national standards before they can enter the market
both metal fuel tank and plastic fuel tank can ensure safety
Professor Xu Xiangyang, deputy dean of School of transportation science and engineering, Beijing University of Aeronautics and Astronautics Table II. Common fault status: the experimental instrument can not reach the rated value. From the perspective of manufacturing technology, the metal fuel tank is mainly made of materials with nickel and zinc plating on the internal and external surfaces. After fpo-3 treatment, the interior of the fuel tank will not rust, and at the same time, The metal oil tank is connected with the negative pole of the battery through the vehicle body, and because of the good conductivity of the metal, there will be no potential difference with the vehicle body, so there will be no electrostatic phenomenon. Even if there is spark when subjected to external impact, it will not cause explosion because of its good sealing and rigidity. As the name suggests, plastic fuel tank is made of plastic raw materials such as polyethylene. It has the rigidity similar to metal, which can also ensure the safety of use
for vehicle combustion accidents caused by collision, most of them are caused by fuel pipeline damage or short circuit of wires in the engine compartment, and there is almost no explosion caused by fuel tank leakage. After years of research and development, metal fuel tanks and plastic fuel tanks can meet the safety needs of vehicles in many aspects. Therefore, no matter what kind of material, consumers can safely choose and use it
both metal and plastic fuel tanks are widely used
in the current international market, both metal and plastic fuel tanks are widely used. After hundreds of years of practical application, metal fuel tanks have not changed the performance of "me" and found potential safety hazards. And metal fuel tanks are used in buses and heavy trucks with higher safety requirements in both European and American markets and domestic markets
Song Jian, executive vice president of the automotive engineering development and Research Institute of Tsinghua University, mentioned that the use of plastic fuel tanks is mainly due to "the consideration of lightweight body, plastic shape, saving internal space and so on". Plastic fuel tank has light weight and strong plasticity. It can be made into a special-shaped fuel tank according to the design of the car to increase the volume of the fuel tank. On the cost, Song Jian introduced that metal is a consumptive resource, and the price of metal has been rising in recent years, while plastic is a chemical product with low price. On the premise of large-scale manufacturing, the manufacturing cost of plastic is lower than that of steel
based on many views, the current facts tell us that safety has nothing to do with fuel tank material. Therefore, what kind of fuel tank is made of cannot be the main factor for consumers to judge whether a car is safe. Consumers should pay more attention to the initiative provided by the vehicle and the passive safety configuration of our ultimate goal is to produce the machine qualified
