Performance, emission, and combustion analysis on diesel engine fueled with blends of neem biodiesel/diesel/ additives

ABSTRACT

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.
