“…Further improved combustion characteristics were documented with all blends tested compared to diesel operation. Similar results have been reported by Ramlingam et al (2019) and Manjunath et al (2018) reported that B20 blend resulted in improved thermal efficiency with increased NOx levels and decreased other regulated emission levels. Influence of B20 and compression ratio on the combustion and emission characteristics of diesel engine using DiSOME has been reported.…”

Present work discusses experimental investigation to study the effect of biodiesel blends and re-entrant combustion chamber on the performance, combustion and exhaust emissions. In the first phase of the work, diary scum oil methyl ester (DiSOME) biodiesel was produced by conventional transesterification process and is blended with conventional diesel fuel in steps of 20 (by volume). Further in the next phase of the work, influence of blended fuel properties and re-entrant combustion chamber (RCC) on the combustion and emission characteristics of a direct injection diesel engine has been investigated. Results of investigation showed that B20 operation with RCC provided increased thermal efficiency by 3-4% with 10% increased smoke, 10-20% decreased hydrocarbon (HC) and carbon monoxide (CO) and 8-10% increased nitric oxide (NOx) emission levels compared to B100 operation. Further increased cylinder pressure and heat release rate were observed with B20. However, Thermal efficiency and NOx emissions are comparatively lower and smoke, HC and CO emissions were found to be slightly higher than base line diesel operation.

“…Due to rich F/A ratio at full load propomote incomplete combustion and reduced the Tcyl (Sharma et al 2021;Jindal et al 2010). This fall in Tcyl reduced the oxidation rate of fuel radicals and slowed the formation of thermal NOx (Channappagoudra and Ramesh 2018;Nagaraja et al 2015). It is clearly seen from Figure 9(a) that the formation of NOx is following the same pattern as HRR: KOME 30 > KOME 20 > KOME 10 > Diesel, as discussed in the above section.…”

“…Authors observed that with increased CRs the engine performance was improve. Higher CR also enhanced combustion, such as maximum pressure, and total HRR and lowered the engine out pollutions of CO, HC, NOx and smoke at higher CR (Channappagoudra and Ramesh 2018).…”

Channappagoudra et al (2018), investigated the effect dairy scum oil biodiesel at different compression ratio ( CR 16, CR17 and CR18) in a stationary engine. Authors observed that with increased CRs the engine performance was improve.…”

<p>Energy is essential but associated with global greenhouse emissions. Therefore, clean and renewable energy is important for future development. To meet this demand, kapok oil methyl ester (KOME) was made from the kapok raw oil through the transesterification method. KOME was then combined with diesel in the ratios of 10%, 20%, and 30% (v/v%) to form KOME10, KOME20, and KOME30 mixtures. The combustion and emissions outcomes of KOME blends were studied at a stationary DI engine under different loads and modified common rail direct injection (CRDI) mode at 400 bar injection pressure, partial load, and CR of 19:1, 20:1, and 21:1. The combustion analysis of blends like maximum pressure (Pmax) and net heat release rate (HRRmax) were observe lesser than diesel at stationary mode, whereas they increased by 13–15% and 16–32% in CRDI mode, respectively. Exhaust from engine such as carbon dioxide, hydrocarbons, and smoke were decreased, but nitric oxide increased about 0.7–1.5% and 1.3–8% for stationary and CRDI modes, respectively, as compared to diesel. This concludes that KOME might be a suitable substitute to diesel fuel for non-road DI engine applications.</p>
