Abstract In this study, exergy, energy, performance and emission analysis were investigated for the repurpose used cooking oil (RUCO), Jatropha curcas (JC), Pongamia Pinnata (PP) and petroleum diesel fuel (PDF) fueled compression ignition engine under various engine loads. In this study, 20% of each biodiesel was tested in single cylinder, four stroke, diesel engine, given that open literature shows the potential use of biodiesel of up to 20% in a diesel engine without modification. The diesel engine was used to investigate their performance, combustion and emission characteristics of diesel-repurpose used cooking oil, Jatropha curcas, and Pongamia Pinnata fuel samples at different compression ratios and load condition. The results showed that thermal efficiency is higher with the PDF compared to DRUCO20, DJC20, DPP20 biodiesel blends. The exhaust gas temperature decreased and specific fuel consumption of the engine were increased by adding RUCO, Jatropha curcas, Pongamia Pinnata to petroleum diesel fuel. Engine ecological analysis showed that blended fuel reduces the average hydrocarbons (HC), carbon monoxide (CO) and NO X than petroleum diesel fuel. While DRUCO20 showed better performance and reduction in ecological analysis but higher ecological of CO 2 is comparable with DCJ20 and DPP20.

The application of fermentation is one of methods to increase food quality biologically. Availability of Jatropha curcas residual from oil factory be focused as a soybean meal or fish meal replacement. On the other hand, J. curcas residuals possess a toxic compound as well. This study aimed to examine the effect of Aspergillus niger on the nutrition and harmful content of J. curcas as a potential ingredient of feed. In brief, J. curcas residual was fermented with a detoxification method at 3 d, 5 d, and 7 d. Crude protein, fat, and crude fiber content were assessed to discover the biological responses of J. curcas post–fermentation while phorbol ester was evaluated to toxic content post–detoxification. The results showed that crude protein and fat content were highest on 7 d post–fermentation but it was no significant difference (p > 0.05). While crude fiber content showed significant difference which the 3 d fermentation had the highest content of fiber. For phorbol ester content, 3 d fermentation showed a better result than the control group (p < 0.05). The present findings suggest that A. niger is recommendable as starter to reduce fiber and toxic content of J. curcas residual at 3 d fermentation.

A two stage esterification process was adopted in producing biodiesel from Jatropha curcas seed oil in a modified batch reactor. The produced fuel was washed and dried before testing it in an unmodified single stroke diesel engine. 10 liters of biodiesel was measured into five containers and blended with fossil diesel at various percentages for optimal performance in the following order; 10% (B10), 20% (B20), 50% (B50) and 70% (B70) while the fifth container was used as control at 100% biodiesel (B100). Constant engine speed test was conducted to investigate the performance of the produced fuel at known operational speeds of most farm machines. Two engine speeds were selected (2000rpm and 1500rpm). Each speed level was selected on the engine when no extra load was on it, then load from the dynamometer was gradually imposed on the system. A drop in speed was noticed and the engine was raised back to the selected speed. It was allowed to stabilize for about 3minutes before recording the spring readings on the tension side of the belt (F₁), and that on the slack side of the belt (F₂), and torque (T) on the belt and other parameters were deduced. The result of the experiment showed the high torque delivering ability of biodiesel and its blends (B10 & B20) and their ability to protect the enginewhile in operationby reducing frictional wear and tear given its high viscosity.
