In this research, Palm Oil Methyl Ester (PME) was added to methanol-biodiesel fuel in order to reduce the emissions. Thus, for diesel engines, alcohols are receiving increasing attention because they are oxygenated and renewable fuels. Therefore, in this study, the effect of PM emission level of a four cylinder, naturally aspirated, indirect injection diesel engine has been experimentally investigated by using methanol-blended diesel fuel from 0% to 20% with an increment of 5%. Thus, the effects of methanol on particulate matter (PM) components, soluble organic fraction (SOF) and dry soot (DS) using different type of fuel blends were investigated. Using a composite filter, the ester-methanol-diesel characteristic such as mass concentration in term PM, SOF and DS were analyzed under different engine operating conditions. The results show that the combination of 10% of methanol with 20% of Palm Oil Methyl Ester gives less PM emissions. Thus, PME20M10 of methanol-biodiesel fuel can reduce the PM emissions effectively for all load condition.

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.

Suitable Modification

The technology for use of biodiesels (up to 20%) as alternative fuel in diesel engines has already been established. In this regard, some suitable modification of biodiesel with appropriate additives may help in increasing the biodiesel component in the biodiesel fuel blends. In order to evaluate the effects of iron nanoparticles (INP) blended palm biodiesel (PB) on the performance and emission characteristics of diesel engine, an experimental investigation is carried out in a single cylinder diesel engine. Methodically, biodiesel prepared from palm oil and commercially available nanosized INP is used in this study. Iron nanoparticles are suspended in the biodiesel in proportions of 40 ppm to 120 ppm using an ultrasonicator. The intact study is conducted in the diesel engine using the four fuel samples, namely diesel, PB20, INP50PB30, and INP75PB30, consecutively. The addition of nano-additive has resulted in higher brake thermal efficiency (BTE) by 3% and break-specific energy consumption (BSEC) by 3.3%, compared to diesel fuel. The emission levels of carbon monoxide (∼56%) and NOx (∼4%) are appreciably reduced with the addition of INP. Increase of INP in the blend from 50 ppm to 75 ppm, BTE and BSEC tend to reduce, but CO and NOx emissions are reduced.

Di Diesel Engine

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.
