This study examines the impact of the oxygenated additives namely DTBP (Di-Tetra-Butyl-Phenol) and 1-Pentadecanol (1-DEC) on emissions, combustion and performance patterns of Karanja biodiesel/diesel blends. Two additives were selected as ignition improver owing to their improved physicochemical properties. The additives were mixed at 10% volume with the equal blends of diesel and biodiesel. Experimental results revealed that by adding additives and biodiesel to diesel found no phase separation. HRR and peak pressure were highest for diesel and least for KBD/D blends. However, blending the additives enhanced its HRR and peak pressure. Addition of additives lowered the harmful emissions significantly with a slight increase in NO emissions to the KBD/D blends. In addition, a noteworthy increase in performance aspects was observed for KBD/D blends by adding DTBP and 1-Pentadecanol.

详细研究不同点火增强剂在柴油/生物柴油的二元混合物中的作用，可替代不变的压缩点火发动机

这项研究检查了含氧添加剂DTBP（二-四丁基-苯酚）和1-十五碳醇（1-DEC）对Karanja生物柴油/柴油混合物的排放，燃烧和性能模式的影响。由于两种添加剂具有改善的理化特性，因此被选作点火改进剂。将添加剂以10％的体积与等量的柴油和生物柴油混合。实验结果表明，向柴油中添加添加剂和生物柴油不会发现相分离。柴油的HRR和峰值压力最高，而KBD / D混合物则最低。但是，共混添加剂可提高其HRR和峰值压力。添加剂的添加显着降低了有害排放，同时KBD / D混合物的NO排放量略有增加。此外，
