欧洲汽车在几年前已成功地使用塑料油管,美国在90年代生产的汽车上已采用这种油管。 从70年代末以来,发动机的设计采用燃油喷射系统者日增,需要有较高压力的供油系统。 为防止油管被燃油侵蚀。燃料系统的燃料或添加剂可以是:无铅汽油,乙烯醇、甲醇基添加物、抗爆剂、清洁剂、水或自动氧化燃料。 目前燃料系统所使用的钢管,用纯燃料时能符合需要。但由于钢管内壁无涂层而暴露于水或自动氧化燃料等添加物,使钢管很快被腐,因此将引起燃料喷射 European cars have succeeded in using plastic tubing a few years ago and the United States has adopted the tubing on cars manufactured in the 1990s. Since the late 1970s, the design of engines has increased by the use of fuel injection systems, requiring higher pressure oil supply systems. To prevent tubing from being eroded by fuel. Fuels or additives to the fuel system can be: unleaded gasoline, vinyl alcohol, carbinol-based additives, antiknock agents, detergents, water, or autoxidative fuels. The current fuel system used by the steel pipe, with pure fuel to meet the need. However, due to uncoated steel pipe wall exposed to water or auto-oxidation of fuel and other additives, the steel pipe is quickly corrupted, it will cause fuel injection
