“…This is most likely cause of relatively lower BTE for KB20. Consistent trends of lower BTE from biodiesel were reported by Banapurmath et al 29 and Pali et al 9 For both test fuels, BSFC decreased with increasing engine load. BSFC for KB20 was higher (at low load: 3.96% and full load: 4.65%) than baseline mineral diesel at all loads.…”

“…Oxygen content of biodiesel led to superior combustion in fuel-rich zones of the combustion chamber compared to mineral diesel, which is a non-oxygenated fuel. 32 Similar results for smoke opacity were also reported by Pali et al 9 Particulate size-number distribution was measured using EEPS spectrometer for KB20 and baseline mineral diesel. Figure 15 shows the variation of particulate size-number distribution with varying engine load at 2500 r/min for KB20 vis-a`-vis mineral diesel.…”

“…Engine management system (EMS) parameters for B30 were optimized for lowering CO and HC emissions at the expense of increased PM emissions. Pali et al 9 conducted experiments on an unmodified single cylinder diesel engine using Kusum biodiesel. Reduction in brake thermal efficiency (BTE), CO, HC and smoke opacity and increased NOx emissions were reported from biodiesel compared to mineral diesel.…”

Internal combustion engine research on alternative fuels has gained momentum because of growing awareness about energy security and environmental issues worldwide. Biodiesel offers an ideal solution to these problems and is an excellent partial replacement to mineral diesel. In this study, Karanja biodiesel blended with mineral diesel has been investigated for macroscopic spray characterization vis-à-vis baseline mineral diesel by varying fuel injection pressures (50, 100 and 150 MPa). Spray developed with relatively narrower spray angle for KB20. Injector needle movement for energizing and real injection durations were also compared for diesel and KB20 at fuel injection pressures of 50, 100 and 150 MPa. Needle movement was slightly higher for KB20 because of its relatively higher viscosity. However, with increasing fuel injection pressure, the difference reduced and showed quite similar results. A 2.2 L common rail direct injection sport utility vehicle EURO-IV diesel engine was used for the experiments. Engine performance, emissions and combustion characteristics of KB20 were compared with baseline mineral diesel at (1) the rated engine speed (2500 r/min) with varying engine loads as well as (2) at the rated load at varying engine speeds (1500-3500 r/min). Brake thermal efficiency of KB20 was lower than mineral diesel. Brake-specific carbon monoxide and carbon dioxide emissions decreased with increasing brake mean effective pressure and showed increasing trend with increasing engine speeds. KB20 showed emission of higher number of particles compared to mineral diesel at all engine operating conditions. Higher oxygen content of biodiesel resulted in shorter ignition delay and slightly higher peak cylinder pressure. KB20 showed relatively longer combustion duration compared to mineral diesel at 2500 r/min engine speed.

“…In another approach to produce SOME, the alkali‐based transesterification was performed using 0.5% ( w /w) KOH as catalyst, 65°C reaction temperature, and 90‐min reaction time with constant stirring at 450 rpm, followed by washing . Under the same process parameters, pilot plant study for biodiesel production for 10 L capacity was successful . In another process, synthesis of methyl ester of sal oil was carried out using INDION 225 H ion‐exchange resin catalyst.…”

“…Similarly, for the transesterification stage, 97.2% ester yield was obtained with 1.4% by mass of catalyst (KOH), 65°C temperature, and 100‐min time with the same 450‐rpm agitation speed. The same process parameters were utilized to produce sufficient quantity of biodiesel in the 10‐L capacity reactor . In method by Sharma et al, they extracted the oil from the seeds of kusum by mechanical expeller at room temperature, maintaining the water content of the feedstock below 0.06%, by heating the oil at 105°C for couple of hours for better conversion of oil to esters.…”
