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.

Pumpkin Seed Oil

In the current study, the primary components used are pumpkin seed oil biodiesel with diesel was tested in diesel engine and its performance, exhaust emissions, and its effects were observed. The pumpkin seed oil that is used to produce biodiesel undergoes transesterification process along with ethanol, sulphuricacid ,andNaOH catalysts . With blends like B0,B20,B40,B60,B80,and B100, the test on engine performance is obtained, and the reports exposed that, B40 is overlying blend among the other biodiesel blends. In addition, to enhance the performance characteristics of B20,B60,B80 by volume was combined with B40 blend. Due to lower heating characteristics of biodiesel, the observations of BTE for B40 is 4.6% lower than diesel. But the observations of BSFC for B40 is 7.3% higher than diesel. The heat emission rate ofB20,B40,andB60 are almost identical to diesel fuel ,apace with ,at higher loads B40 emitted37.5%less CO and NOx emission was raised at the rate of 95% when correlated to diesel fuel. However, It is observed that there is no major difference not much difference in the emissions (HC, NO, andCO) and characteristics of the engine when using the diesel fuel and Pumpkin seed biodiesel fuel blends
