进行燃油系统气密性、通气性在线检测是贯彻轻型汽车欧Ⅱ排放标准时所执行的生产一致性检查中必不可少的项目之一。文中对燃油系统气密性、通气性在线检测的调试过程进行了讲解,并对如何将国家检测标准转换成线体生产检测标准进行了阐述。
Conducting fuel system gas tightness and air permeability on-line testing is one of the essential items in the production consistency check carried out when implementing Euro II emission standard for light vehicles. In this paper, the debugging process of air tightness and ventilation on-line testing of fuel system is explained, and how to convert the national testing standard into the testing standard of the line body is also described.
