Development of automotive plastic fuel tank products

compared with steel plate fuel tank, automotive plastic fuel tank has the characteristics of more safety, corrosion resistance and long service life, and can meet the development needs of automotive lightweight to meet the new automotive fuel economy standards. Therefore, with the development of Automotive industry, the market share of plastic fuel tank in the upper and lower yield points has been rapidly increased, reaching 60% in 2001

overview of the development of plastic fuel tanks in the world

the legal person organizations of manufacturers and units such as the first Jinan period test in the world participated in the formation of an automobile plastic fuel tank, which was jointly researched and developed by German Volkswagen, BASF and Kautex in the 1960s and was successfully used in Porsche sports cars. Its output of plastic fuel tanks in 2001 was about 31million

the development of China's automotive plastic fuel tank started in Jiangsu Yangzhou No.2 plastic factory (the predecessor of Yangzhou Yapu automotive plastic parts Co., Ltd.). In 1987, the factory imported plastic fuel tank production equipment and technology from Krupp Kautex company and Volkswagen Company in Germany, realizing the localization of plastic fuel tanks for Santan car of Shanghai Volkswagen Co., Ltd. and Peugeot 505 car of the former Guangzhou Peugeot Automobile Co., Ltd. After 15 years of development, the market share of plastic fuel tanks in China's passenger car market has reached 44%. The manufacturer of plastic fuel tanks has also evolved from Yangzhou yapp automotive plastic parts Co., Ltd. (yapp) "outshining others" to a situation in which Changchun Clivia Kautex company is located in the northeast, Ti (Tianjin) company is located in the north, and Yachiyo company is located in the south

development of plastic fuel tank technology

regulatory requirements: with the improvement of automotive environmental protection requirements, governments or economic communities around the world have implemented different regulations to control automotive exhaust emission indicators in different market areas. From 2000 to 2010, the Chinese government has gradually implemented exhaust emission standards equivalent to EU I, EU II, EU III, EU IV and EU V directives of the European Community in the automotive market

the vehicle pollutant evaporative emission control regulation is a requirement for the vehicle system, so only improving the impermeability of the plastic fuel tank can not fully achieve the goal. We must optimize the overall scheme from the structure of the fuel tank system and the structure and performance of its key parts to ensure that the HC compound emission limit of the fuel system meets the regulatory requirements

plastic fuel tank technology: fuel system is one of the main sources of HC compounds in vehicle pollution emissions. The research shows that 45% of the vehicle HC compound emissions come from the fuel system and crankcase, so improving the impermeability of plastic fuel tank has become the most direct, effective and important way to meet the vehicle exhaust emission standard. At present, based on the single-layer blow molding technology, three technologies have been developed to improve the impermeability of plastic fuel tanks: vulcanization/fluorination technology, SELAR (R) technology and multi-layer coextrusion technology. Considering the stability of production process control and product quality, and meeting the requirements of new exhaust emission regulations, multi-layer coextrusion technology is the mainstream development direction of plastic fuel tanks

as Europe is the birthplace of plastic fuel tanks, its market now covers a variety of plastic fuel tanks; The United States and Japan are stricter in controlling the emission of automobile pollutants than Europe, and the commercial application of plastic fuel tanks is later than Europe, so they adopted multi-layer co extrusion technology to promote the development of plastic fuel tanks at the beginning; The technical status and development process of China's automotive plastic fuel tank is basically a replica of Europe

development of plastic fuel tank structure

the development trend of the main components in the plastic fuel tank system is the tube: the outer tube is a multi-layer structure, and the inner tube is Pa; Filler neck: extra molded inserts with ICV; Refueling pipe welding; Sending unit: H-shaped sealing structure; D-type sealing structure

the development technology of plastic fuel tank system in the future mainly includes: Kautex Textron's plastic fuel tank system develops the coextrusion technology of six layers and four materials; Ti Walbro mainly develops coextrusion technology of 6 layers and 5 materials

with the implementation of the new standard of automotive fuel economy, automotive lightweight will become one of the key directions of automotive technology development in the future. Therefore, the development of plastic fuel tanks is completely consistent with the direction of automotive technology. Almost all new models to be put into production in the Chinese market use plastic fuel tanks, such as Mondeo car of Changan Ford company, fit car of Guangzhou Honda company, Avante XD car of Beijing Hyundai company, PQ35 car of Shanghai Volkswagen Company and FAW Volkswagen Company, etc. By 2005, the output of cars in China will reach million, and the utilization rate of plastic fuel tanks will reach 86%. China's automobile market is a microcosm of the world's automobile industry, which shows that there is great room for the development of plastic fuel tanks. (end)
