“…It is observed from the figure that the NOx emission increases with the load as well as with the BMEP for all fuels. This is because NOx emission depends mainly on the oxygen concentration, peak temperature, engine dimension, operating condition and fuel injection angle [38,39]. As the load increases for the same amount of air in the cylinder, the fuel consumption is increased.…”

Performance and emission comparison of Karanja (pongamia pinnata), Pithraj (aphanamixis polystachya), Neem (azadira chtaindica) and Mahua (madhuca longofolia) seed oil as a potential feedstock for biodiesel production in Bangladesh ABSTRACTThis paper investigates the production of biodiesel (BD) from karanja (Pongamia pinnata), pithraj (Aphanamixis polystachya), neem (Azadira chtaindica) and mahua (Madhuca longofolia) seed oil through acid esterification, followed by the investigation on the transesterification process and physicochemical properties of oils. This study also includes their effects on engine performance and emission on a direct ignition (DI) diesel engine. A maximum 9 of 6% by volume methyl ester (biodiesel) was obtained from mahua oil at methanol concentration of 22vol%, catalyst concentration of 0.5wt% and a temperature of 55°C and at the same condition 94%, 92% and 91% biodiesel extraction was experienced for neem, pithraj and karanja seed oil respectively. The diesel-biodiesel blend (B10) has been used during the test run and it was found that all of the fuels showed performance closer to the neat diesel. Among all the biodiesels, karanja showed better performance compared to the other three. On the other hand, high oxygen content of biodiesel causes less CO and NOx emission. It was experimentally found that mahua emits the least amount of CO and NOx which were 44.44% and 38.3% respectively compared to the neat diesel. Results indicate that these oils are potential biodiesel feedstock and can be used as an alternative to the diesel fuel in the near future. Desirable engine performance and tail pipe emissions are also observed during the experimental investigation.

“…Biodiesel is nothing but longchain alkyl esters which is obtained from animal fat and plant seeds. They are regarded as a carbon sink as they absorb 78.5% of carbon in the atmosphere as they burn and even considered as cleaner than fossil fuels [5] [6].…”

“…But the requirement of land is much less demanding as compared to those for edible biomass feedstocks preparations [10]. The non-edible biomass feedstocks include mainly the oils from non-edible vegetables, such as Jatropha curcas (Jatropha) [11,12], Linum usitatissimum (Linseed) [13], Simmondsia chinesnsis (Jojoba) [14], Hevea brasiliensis (rubber seed) [15], Azadirachta indica (Neem) [16], Cotton seed [17], Calophyllum inophyllum (Polanga) [11], Nicotianna tabacum (tobacco) [18], Pongamia pinnata (karanja) [19] and Maduca indica (mahua) [20].…”

a b s t r a c tBiodiesel is a renewable and sustainable biofuel. There are various production processes to produce biodiesel from different kinds of raw materials. In this study, the environmental impacts of biodiesel production from non-edible Jatropha oil and waste cooking oil (WCO) were investigated and compared using systematic life cycle assessment. The results show that crops growing and cultivation of non-edible Jatropha curcas lead to higher environmental impacts compared to WCO process. However, biodiesel production process from Jatropha oil has better performance because the WCO process needs to consume variety of chemicals and requires a large amount of energy for the pretreatment of raw WCO and further chemical conversion to biodiesel. Results also indicate that the collection mechanism of WCO has significant contributions towards environmental impacts. In general, biodiesel production from Jatropha oil shows higher impacts for damage categories of climate change, human health and ecosystem quality whereas biodiesel production from WCO has more severe environmental impacts for resource category. The total environmental impact is 74% less in case of using WCO as raw material compared to non-edible Jatropha oil.
