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。The detergency of vehicle gasoline is closely related to vehicle exhaust emissions and fuel economy.In order to improve the detection efficiency of gasoline detergency and enhance the supervision ability of relevant functional departments,an on-board multi-channel rapid simulation detection(MCRSD)method of gasoline detergency was proposed.Compared with the rapid simulation detection(RSD)method of gasoline engine inlet valve deposits recommended by the regulations,the total test time for a single sample of the MCRSD method decreased by 77.8%,and the total test time for multiple samples of the method decreased by 94.4%,with 80%reduction in fuel consumption and 90%reduction in cost.The MCRSD method had a good correlation with the RSD method(Pearson correlation coefficient was 0.4-0.8),and could be used for the rapid detection of gasoline detergency.Finally,the on-site supervision and testing scheme of gasoline detergency was proposed.
