“…The Biodiesel from MSO, when compared with Conventional diesel during the engine test indicated lower specific fuel consumption (SFC). And the Brake thermal efficiency of Biodiesel was found to be slightly higher (17.4%) than that of Conventional diesel at increased speeds, for various increasing load conditions, which is in agreement with [21].…”

Biodiesel in the past, was once considered a fringe fuel. However today, the production and consumption of this fuel has grown as a sustainable and much more eco-friendly alternative to the Conventional diesel (Petroleum diesel), for diesel engines; if not in pure form, it will be in blends of different ratios, or as a fuel additive, to improve engine performance and ensure longevity. In this research, oil from Mango (Mangifera indica) seed was extracted through Soxhlet solvent process, and converted into biodiesel by the method of Transesterification. This process involved the reaction between the extracted oil and methanol at an optimal temperature of 60°C, and 1%w/v of the catalyst (KOH) concentration for optimal yield of biodiesel. The produced biodiesel was analyzed and evaluated by comparing its physical characteristics to that of Conventional (petroleum) diesel fuel. The properties analyzed were; Density, Heating value, flash point, specific gravity, viscosity, cloud point, water content and pour point. The biodiesel from mango seed oil (MSO) compared excellently well with the values obtained for the commercially available petroleum diesel, dispensed at government approved filling stations in Nigeria. The biodiesel so produced and characterized, was subsequently subjected to an engine test, in a four-stroke internal compression (IC), (diesel) engine loaded between 120 – 200 rpm, to determine its suitability as a fuel. The result was compared with the Conventional diesel characteristics in terms of brake power output, mass flow rate, thermal efficiency, and specific fuel consumption (SFC) and so on. The biodiesel results compared very well with most of the data generated on the conventional diesel, and satisfied the ASTM-D6751 and the EN14214 standard requirements for suitability as working fluid in an IC engine, especially with regard to SFC, which translates to the direct running cost of every diesel engine.

“…The rise in CO emissions is noticed when the load percentage increases (Sundaresan et al, 2007). Smoke opacity falls as the biodiesel content in the blend rises, but increases when the load increases for Jatropha biodiesel and its blends (Chauhan et al, 2012;Pandhare and Padalkar, 2013). The engine performance and emissions while utilising Jatropha Curcas based biodiesel for different test conditions are summarised in Table 5.…”

This article looks at the national and global actors, social networks, and narratives that have influenced Jatropha’s worldwide acceptability as a biofuel crop. Jatropha Curcas is a genus of around 175 succulent shrubs and trees in the Euphorbiaceae family (some of which are deciduous, such as Jatropha Curcas L.). It’s a drought-tolerant perennial that thrives in poor or marginal soil and produces a large amount of oil per hectare. It is easy to grow, has a fast growth rate, and can generate seeds for up to 50 years. Jatropha Curcas has been developed as a unique and promising tropical plant for augmenting renewable energy sources due to its various benefits. It is deserving of being recognised as the only competitor in terms of concrete and intangible environmental advantages. Jatropha Curcas is a low-cost biodiesel feedstock with good fuel properties and more oil than other species. It is a non-edible oilseed feedstock. Thus it will have no impact on food prices or the food vs fuel debate. Jatropha Curcas emits fewer pollutants than diesel and may be used in diesel engines with equivalent performance. Jatropha Curcas also makes a substantial contribution to the betterment of rural life. The plant may also provide up to 40% oil yield per seed based on weight. This study looks at the features characteristics of Jatropha Curcas as biodiesel feedstock and performance, and emissions of internal combustion engine that operates on this biodiesel fuel.

“…Consumption of fuel increased from 2.75 to 15% for fuels B10 to B100. 13 Exhaust gas temperature (EGT) increased with a higher biodiesel blend. Highest observed temperature in the exhaust gases was 430 °C with biodiesel under the loading conditions of 1.5–3.5 kW, while for diesel the maximum exhaust gas leakage temperature is 440 °C.…”

Methyl ester production from jatropha–algae oil is conducted through a transesterification process. Consequences of four parameters, the molar ratio (oil:methanol), the reaction temperature, the amount of catalyst, and the reaction time for obtaining a higher yield of biodiesel, are derived, and the process was optimized using the response surface methodology based on the Box–Behnken Design. An optimized biodiesel yield of 96% is achieved at a molar ratio of 1:10, a reaction temperature of 53° C, a 0.3 wt% catalyst, and a reaction time of 172 min. The predicted optimal conditions were experimentally validated with a relative error of 4% of the experimental result (96%). The P value of ANOVA is <0.0001, which shows that the model is significant. Finally, the performance and emissions in a diesel engine coupled with an electricity generator powered by biodiesel blends (B0, B5, B10, and B20% vol.) were investigated, concluding a significant reduction of exhaust gases. The engine was run with numerous blends of biodiesel by changing the brake power from 0 load to 0.5, 1, 1.5, and 2 KW.
