Abstract In this paper, alternative advanced combustion methods were investigated by conducting experiments at common operation condition (2000 rpm, 6.6 mg fuelling) of EURO-5 capable 1.5-liter diesel engine under NEDC. Single and double injection configurations of 6.6 mg at 2000 rpm were studied by adjusting SOI and EGR with pure diesel and biodiesel blended diesel. Power, NOx, Opacity, Start of Combustion and combustion data of the studied points were compared with the original condition of the 1.5 L diesel engine of the Ford Fiesta. Adjusting SOI and EGR for double injection configuration allowed reducing NOx emission from 65 ppm to 29 ppm and Opacity emission 1.2% to 0.2%. Utilization of biodiesel at single injection configuration reduced power almost 4% compared to pure diesel. More than 15% increase was observed for NOx emission, while opacity emission reduced 20% with biodiesel blended diesel compared to pure diesel. Although addition of biodiesel worsen the power, proposed advanced combustion method with pure diesel improve opacity, NOx and power compared to original condition of the engine.

柴油和生物柴油混合柴油在部分负荷条件下部分预混压燃燃烧的评价

摘要 在本文中，通过在NEDC 下具有EURO-5 能力的1.5 升柴油发动机的常见操作条件（2000 rpm，6.6 mg 燃料）下进行实验，研究了替代的先进燃烧方法。通过使用纯柴油和生物柴油混合柴油调整 SOI 和 EGR，研究了 2000 rpm 下 6.6 毫克的单喷射和双喷射配置。将研究点的功率、NOx、不透明度、燃烧开始和燃烧数据与福特嘉年华的 1.5 L 柴油发动机的原始条件进行了比较。调整双喷射配置的 SOI 和 EGR 允许将 NOx 排放从 65 ppm 减少到 29 ppm，将不透明度排放从 1.2% 减少到 0.2%。与纯柴油相比，在单次喷射配置下使用生物柴油可将功率降低近 4%。观察到 NOx 排放量增加了 15% 以上，与纯柴油相比，生物柴油混合柴油的不透明度排放降低了 20%。尽管添加生物柴油会降低功率，但与发动机原始状态相比，提出的纯柴油先进燃烧方法可改善不透明度、NOx 和功率。
