Biodiesel, a derivative of vegetable oils and animal fats, is used nowadays as an alternative renewable and sustainable fossil fuel. In this work, the investigation of manufacture, characterization, and results of biodiesel blends are carried out using two important feedstock’s, sunflower oil and ricebran oil on engines. For the collective advantageous of sunflower oil and ricebran oil, the two biodiesels are combined together and the mixture is analysed to assess the engine performance and emission characteristics. NaOH catalyzed transesterification process is used for producing the Biodiesels A 4.4 kW, four-stroke, single-cylinder and direct fuel injection diesel engine is used for measuring physic-chemical with full load and varying speed conditions and using the specifications of ASTM D6751 standard, the properties are compared. It is observed that the Biodiesel mixtures produce a low brake torque and high brake-specific fuel consumption (BSFC) in addition to the reduction of CO and HC emissions. NOx, however, is reduced considerably with the improvement of brake thermal efficiency. The Performance analysis indicates that the mixture of sunflower oil and ricebran oil improves performance and emission characterizes over sunflower oil and ricebran oil biodiesel when they are unmixed..

This paper presents the investigation of engine optimisation when plastic pyrolysis oil (PPO) is used as the primary fuel of a direct injection diesel engine. Our previous investigation revealed that PPO is a promising fuel; however the results suggested that control parameters should be optimised in order to obtain a better engine performance. In the present work, the injection timing was advanced, and fuel additives were utilised to overcome the issues experienced in the previous work. In addition, spray characteristics of PPO were investigated in comparison with diesel to provide in-depth understanding of the engine behaviour. The experimental results on advanced injection timing (AIT) showed reduced brake thermal efficiency and increased carbon monoxide, unburned hydrocarbons, and nitrogen oxides emissions in comparison to standard injection timing. On the other hand, the addition of fuel additive resulted in higher engine efficiency and lower exhaust emissions. Finally, the spray tests revealed that the spray tip penetration for PPO is faster than diesel. The results suggested that AIT is not a preferable option while fuel additive is a promising solution for long-term use of PPO in diesel engines.

In this study, Biodiesel -Dimethyl Ether (BDE) and Biodiesel Ethanol (BE) were tested in a 4-cylinderdirect-injection diesel engine to investigate the performance and emission characteristics of the engine underfive engine loads at the maximum torque. The engine speed was maintained at 1500 rpm. Here the jatropha oilis used as a non edible oil to produce the biodiesel. The ethanol and dimethyl ether is used as an additive toenhance the engine combustion. The BDE 5 (biodiesel 95% and dimethyl ether 5%) , BDE 10 (biodiesel 90%and dimethyl ether 10%) BDE 15(biodiesel 85% and dimethyl ether 15%) BE5 (biodiesel 95% and ethanol 5%),BE10 (biodiesel 90% and ethanol 10%) and BE15 (biodiesel 85% and ethanol 15%) were tested in the engine.The results indicate that when compared with neat jatropha, the engine performance increased and emissionlevel decreased with adding the ethanol and diethyl ether with methyl ester of jatropha oil. In comparison withneat jatropha, the BDE5 and BE15 blends have higher brake thermal efficiency (BTE) of 12% and 13%respectively. The experimental results showed that the CO, HC emission is decreased and NOx emission isincreased for higher blends of additives. The brakes specific fuel consumption (BSFC) decreased for BDE5 andBE5 compared to other combination of fuel.DOI: http://dx.doi.org/10.3329/jme.v42i1.15941
