This work investigates the effect of two oxygenated additives, DMC (Di-methyl-carbonate) and Pentanol (n-P) on ignition patterns of biodiesel/diesel blends in the diesel engine. DMC and Pentanol were mixed at 10% volume with the equivalent blends of neem-biodiesel and diesel. Blending additives and biodiesel to diesel was carried out without any surfactant and found no phase-separation and remained stable. Performance results revealed a significant improvement in the performance pattern of biodiesel/diesel blends. BSFC is lowered by '0.4 and 0.5 g/kW with 0.3 and 0.6% increase in BTE was observed by blending DMC and Pentanol to base fuel (NBD50D50) respectively. Adding 10% Volume of Pentanol and DMC lowers the CO emission of NBD50D50 by 4.9% and 7.4% at all loads. In addition, 3.1% and 4.7% reduction in HC emissions were observed by blending 10% of DMC and Pentanol to base fuel in that order. Peak pressure of base fuel is increased by 2.3 and 3.1 bar by adding DMC and pentanol, respectively. Further, 3.9 and 2.1 J/CA of HRR is improved by adding DMC and pentanol to NBD50D50 due to its improved properties.

这项工作研究了两种含氧添加剂DMC（碳酸二甲酯）和戊醇（nP）对柴油发动机中生物柴油/柴油混合物点火方式的影响。DMC和戊醇以10％的体积与印度em生物柴油和柴油的等价混合物混合。在没有任何表面活性剂的情况下将添加剂和生物柴油与柴油混合，发现没有相分离并保持稳定。性能结果表明，生物柴油/柴油混合物的性能模式有了显着改善。通过将DMC和戊二醇分别掺入基础燃料（NBD50D50），可以观察到BSFC降低了'0.4和0.5 g / kW，BTE分别提高了0.3％和0.6％。在所有负载下，添加10％体积的戊醇和DMC可将NBD50D50的CO排放量降低4.9％和7.4％。此外，分别为3.1％和4。通过按顺序将10％的DMC和戊醇混合到基础燃料中，可以观察到HC排放量减少7％。通过添加DMC和戊醇，基础燃料的峰值压力分别增加2.3和3.1 bar。此外，由于其改善的性质，通过将DMC和戊醇添加到NBD50D50中来改善HRR的3.9和2.1J / CA。
