A rapid detection method for gasoline detergency and the regulatory scheme

  • 摘要:

    车用汽油清净性与汽车尾气污染物排放水平、燃油经济性等密切相关。为提高汽油清净性检测效率、提升相关职能部门的监管能力,提出了一种车载移动式多通道汽油清净性快速模拟检测方法(简称多通道快速模拟检测法)。与我国法规推荐的汽油机进气阀沉积物模拟试验方法(简称快速模拟检测法)相比,多通道快速模拟检测法的单个油样检测总耗时降低77.8%,多个油样检测总耗时降低94.4%,检验用油量减少约80%,成本降低约90%;多通道快速模拟检测法与快速模拟检测法具有较好的相关性(皮尔逊相关系数为0.4~0.8),可用于汽油清净性的快速检测。最后,提出了汽油清净性的现场监管检测方案。
