【摘要】 对第17号全球技术法规(GTR17)的内容进行详细的研究,总结出法规中曲轴箱污染物排放试验和燃油蒸发污染物排放试验的具体要求。曲轴箱污染物排放试验在制造商提供有效证明材料的基础上可以免除Ⅲ型试验。燃油蒸发污染物排放试验包括:非金属燃油箱渗透排放试验、燃油箱和燃油管渗透排放试验、整车的密闭室(SHED)试验。根据不同的车辆分类和油箱材质,制造商可以选择进行必要的试验来满足Ⅳ型试验的要求。更多还原

【Abstract】 The specific requirements of crankcase emissions test and evaporative emissions test are given,through studying on Global technical regulation No.17. The manufacturer could request avoid the crankcase emissions test, if they provide effective certification documents. The evaporative emissions test includes: permeability test of a non-metallic fuel tank as component; permeation test of the fuel storage and delivery system; SHED test of the whole vehicle. Depending on the classification of the vehicle and the fuel tank material, the manufacturer may choose the necessary tests to meet the requirements of the evaporative emissions test.更多还原
