This investigation studied the size distributions of particulate matter (PM), particulate carbon, and polycyclic aromatic hydrocarbons (PAHs) that are emitted from a generator that is fueled by diesel that is blended with waste-edible-oil-biodiesel and water-containing acetone. PM samples were collected using a micro-orifice uniform deposit impactor (MOUDI) and a Nano-MOUDI (with aerodynamic diameters of 0.01-18 μm). The results reveal that waste-edible biodiesel blended with water-containing acetone (W5WA3 or W20WA3) at a load of 3 kW emitted lower ΣPM, ΣPM-EC, ΣPM-OC, ΣT-PAHs or ΣT-BaPeq concentrations than did D100, in all 13 particle size ranges, and these reductions of emissions of submicron particles exceeded 85%. Furthermore, W20WA3 emitted significantly lower concentrations of Total-PAHs and Total-BaPeq in four nano/ultrafine particle size ranges. Therefore, water-containing acetone biodieselhols can be utilized as alternatives to petroleum diesel as fuel to reduce the dangers to human health that are posed by emissions from diesel engines.
本研究考察了由掺水丙酮生物柴油的废弃食用油生物柴油和水燃料的柴油机所排放的颗粒物（PM）、颗粒碳和多环芳烃（PAHs）的粒径分布。PM 样品采用微孔均匀沉积撞击器（MOUDI）和纳米微孔均匀沉积撞击器（Nano-MOUDI）（空气动力学直径为 0.01-18μm）收集。结果表明，在 3kW 负荷下，掺水丙酮的废弃食用油生物柴油（W5WA3 或 W20WA3）在所有 13 个粒径范围内，其 ΣPM、ΣPM-EC、ΣPM-OC、ΣT-PAHs 或 ΣT-BaPeq 浓度均低于 D100，其中对亚微米颗粒的排放减少超过 85%。此外，W20WA3 在四个纳米/超细颗粒粒径范围内的总多环芳烃和总 BaPeq 浓度显著降低。因此，含水丙酮生物柴油醇可用作替代石油柴油的燃料，以降低柴油机排放对人类健康的危害。
