This study investigated the particulate matter (PM), particle-bound carbons, and polycyclic aromatic hydrocarbons (PAHs) emitted from a diesel-engine generator fuelled with blends of pure fossil diesel oil (D100) and varying percentages of waste-edible-oil biodiesel (W10, 10 vol %; W20, 20 vol %; W30, 30 vol %; and W50, 50 vol %) under generator loads of 0, 1.5, and 3 kW. On average, the PM emission factors of all blends was 30.5 % (range, 13.7-52.3 %) lower than that of D100 under the tested loads. Substituting pure fossil diesel oil with varying percentages of waste-edible-oil biodiesel reduced emissions of particle-bound total carbon (TC) and elemental carbon (EC). The W20 blend had the lowest particle-bound organic carbon (OC) emissions. Notably, W10, W20, and W30 also had lower Total-PAH emissions and lower total equivalent toxicity (Total-BaP(eq)) compared to D100. Additionally, the brake-specific fuel consumption of the generator correlated positively with the ratio of waste-edible-oil biodiesel to pure fossil diesel. However, generator energy efficiency correlated negatively with the ratio of waste-edible-oil biodiesel to pure fossil diesel.
本研究调查了在发电机负荷为 0、1.5 和 3kW 时，使用纯化石柴油（D100）和不同百分比的废食用油生物柴油（W10、10 体积%；W20、20 体积%；W30、30 体积%和 W50、50 体积%）混合燃料的柴油机发电机排放的颗粒物（PM）、颗粒结合碳和多环芳烃（PAHs）。平均而言，与测试负荷下的 D100 相比，所有混合物的 PM 排放因子均降低了 30.5%（范围为 13.7-52.3%）。用不同百分比的废食用油生物柴油替代纯化石柴油可减少颗粒结合总碳（TC）和元素碳（EC）的排放。W20 混合物的颗粒结合有机碳（OC）排放量最低。值得注意的是，与 D100 相比，W10、W20 和 W30 的总多环芳烃（Total-PAH）排放量和总等效毒性（Total-BaP(eq)）也较低。此外，发电机的比燃料消耗与废食用油生物柴油与纯化石柴油的比例呈正相关。然而，发电机的能源效率与废食用油生物柴油与纯化石柴油的比例呈负相关。
