Physicochemical Characteristics of Real-World PM Emissions from Heavy-Duty Diesel Buses

  • 摘要: 为研究重型柴油公交车实际道路颗粒物排放的理化特征,采用车载排放测试方法,选取了2辆国Ⅲ和4辆国Ⅳ柴油公交车,对气态污染物和颗粒物排放因子、粒径分布及颗粒物中的组分(包括碳组分、离子、元素和有机组分)排放特征进行了实测分析.结果表明:测试车辆的颗粒数量主要集中在100 nm以下粒径段,颗粒质量排放总体呈倒U型分布,粒径峰值位于300 nm左右.OC和EC分别占尾气颗粒物总质量的36.10%±8.94%和27.97%±10.00%,离子和元素组分分别占7.75%±1.01%和22.71%±3.09%.柴油质量对柴油车尾气颗粒物成分具有较大影响,燃用国Ⅲ柴油的车辆尾气中富含S、Ca、Mg、Na等元素组分,其主要来自燃油中的硫分和杂质.在可检出的弱极性可溶有机物中,正构烷烃和脂肪酸的含量较为丰富,分别占颗粒物总质量的1.95%和5.13%,此外还有一定量的藿烷和PAHs(多环芳烃).其中,正构烷烃组分主要分布于C19~C29,正构烷酸主要集中在C12、C14、C16和C18等偶数碳组分.国Ⅲ和国Ⅳ柴油公交车的PAHs排放因子分别为198.2、62.5 μg/km,以3环和4环PAHs为主,菲、荧蒽、芘、惹烯、苯并荧蒽、、苯并[123-cd]芘和苯并苝是较为主要的PAHs组分.需要指出的是,由于采用定比例稀释方法,颗粒物中组分的测试结果可能与其实际排放存在一定偏差.
