Environmental contamination has been increasing day by day due to increase in use of fossil fuel, therefore world is moving towards unconventional sources of energy generation. In this study, a diesel engine characteristic was analysed in a single cylinder, four strokes, water cooled, direction injection (DI) diesel engine by using two different fuel blends, one is non-edible oil (Moringa oleifera) and another one is alcohol (Ethanol) and operating at different engine load. Diesel engine characteristics were examined in terms of engine performance, emission and combustion characteristics by using Diesel-RK software and before that validate the numerical result with experimental result. The result shows that MB20 has reduction of 2.26%, 7.37%, 2.6%, 8.3% and 15.02% in BTE, EGT, Smoke emission, MRPR and NOX respectively and increases 8.9% and 12.34% in SFC and CO2 emission. The MBE20 has increased by 2.9% and 18.75% in SFC and CO2 emissions and decrease of 1.25%, 2.45, 5.44%, and 3.06% in BTE, EGT, MRPR and NOX respectively was found as compare to diesel fuel. In this paper, mixing various blends 20% of Moringa Oleifera biodiesel fuel with 20% of ethanol gives optimum blends ratio.

In this study, the sunflowers oil was utilized as for producing biodiesel via a chemical operation, which is called trans-esterification reaction. Iraqi diesel fuel suffers from high sulfur content, which makes it one of the worst fuels in the world. This study is an attempt to improve the fuel specifications by reducing the sulfur content of the addition of biodiesel fuel to diesel where this fuel is free of sulfur and has a thermal energy that approaches to diesel.20%, 30% and 50% of Biodiesel fuel were added to the conventional diesel. Performance tests and pollutants of a four-stroke single-cylinder diesel engine were performed. The results indicated that the brake thermal efficiency a decreased by (4%, 16%, and 22%) for the B20, B30 and B50, respectively. The increase in specific fuel consumption was (60%, 33%, and 11%) for the B50, B30, and B20 fuels, respectively for the used fuel blends compared to neat diesel fuel. The engine exhaust gas emissions measures manifested a decreased of CO and HC were CO decreased by (13%), (39%) and (52%), and the HC emissions were lower by (6.3%), (32%), and (46%) for B20, B30 and B50 respectively, compared to diesel fuel. The reduction of exhaust gas temperature was (7%), (14%), and (32%) for B20, B30 and B50 respectively. The NOx emission increased with the increase in biodiesel blends ratio. For B50, the raise was (29.5%) in comparison with diesel fuel while for B30 and B20, the raise in the emissions of NOx was (18%) and...

An organic compound, Dioxane, is blended to reduce the viscosity of raw vegetable oil (Mahua). A dilute blend was prepared by mixing with raw vegetable oil (Mahua) and 10% dioxane in volume basis. Tests were conducted on a single cylinder, water cooled, DI diesel engine coupled with the eddy current dynamometer. Emissions like HC, NOX, etc., were measured by using gas analyzer and smoke density was measured by using smoke meter. The cylinder pressure, heat release rate were measured by combustion analyzer. From the experimental investigation, it was observed that operating at a blend ratio of 10% diesel-80% mahua oil-10% Dioxane significantly reduced the HC and NOx emissions when compared to diesel fuel. It was also observed, the variation of break thermal efficiency is almost same to that of diesel fuel. Hence, it can be concluded that raw vegetable oil (mahua) with Dioxane blend could partially replace the diesel, as a fuel.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.
