浅谈国六供油系统设计

Brief Discussion On China 6 Fuel System Design

为防止机动车污染物排放对环境的污染,改善环境空气质量,国家标准化技术委员会制定了《轻型汽车污染物排放限值及测量方法(中国第六阶段)》标准,并于2020年7月1日实施。标准中整车蒸发污染物排放限制加严,并新增了加油污染物排放限值要求,因此,文章从这两方面对供油系统关键零部件的设计进行了探讨,提出有效的解决方案。

In order to prevent the environment pollution, improve air quality, ＂Limits and measurement methods for emissions from light-duty vehicles（China 6）＂ standard will implement on July 1, 2020. Standard of vehicle evaporation pollutant emission limits tightened, And the emission limit value of refueling pollutant is added. Therefore, This article discusses the design of key parts of fuel system from both aspects, And puts forward effective solutions.
