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.

The intent of this paper is to summarize the state of knowledge on use of vegetable oils as diesel fuels. Fuel related properties are reviewed and compared with conventional diesel fuel. The use of neat vegetable oil (edible and/or nonedible), biodiesel and its blends in a diesel engine has been discussed. Performance and emission characteristics are highlighted. Suitability of different combustion chambers for diesel engine operation with vegetable oils is outlined. Techniques to decrease viscosities are discussed. An overview on current developments on the use of vegetable oils directly and indirectly in diesel engines is presented.

Performance And Emission

Biodiesel has become more attractive recently, because of its environmental benefits and the fact that it is made from renewable resources. Over the past few decades, most of the countries depending on diesel engines for transportation. Some of its valuable advantages like highest thermal efficiency made it very popular. At the same time, the cost of diesel fuel is increasing, due to the depletion of fossil fuels. In this current scenario, we need an alternative fuel instead of diesel fuel. Many of the researchers have successfully placed several works on generating energy from different types of alternative sources including solar and some kind of conversion processes including renewable agricultural products into liquid fuel. One of the biggest challenges for developing countries in relation to energy consumption is to develop and implement technologies that help to improve efficiency of automobile engines, also to reduce the emissions of harmful gases and particulate matters. In order to avoid environmental impacts, emissions are reduced or eliminated by introducing renewable energy resources. The present research chronicles the production and testing of renewable biodiesel fuel derived from virgin coconut oil on a diesel engine, to analyses the engine performance and emission characteristics. In the first phase of work, production of biodiesel fuel from virgin coconut oil using transeterification process with two types of catalysts (homogenous and heterogeneous). The preliminary results shows that, with the addition of homogenous catalyst called Potassium Hydroxide (KOH) with methanol shows much higher activity than that of heterogeneous catalysts, and it shows more similar properties with diesel fuel. The results obtained from the chemical test and physicochemical properties of transesterified biodiesel fuel clearly proves the above-mentioned statement. The chemical tests such as GCMS and FT-IR clearly shows that the biodiesel fuel has sufficient amount of volatile components and functional groups. Then, physicochemical properties include, Fire point, Flashpoint, density, and viscosity were analyzed. Finally, Engine performance and Emission characteristics were analysed to confirm, whether this biodiesel fuel is suitable for diesel engines, without any engine modifications. It was found to be, the transesterified virgin coconut oil biodiesel has similar properties to that of the diesel fuel. From the physiochemical properties and engine performance clearly shows that, coconut oil biodiesel is suitable for diesel engine on blending, at a blending percentage level of 20% with conventional diesel fuel. Since the obtained transesterified biofuel can be used as an alternative fuel for diesel engines. The several journal reports and find outs from experimental investigation clearly depicts that the efficiency of the transesterified biofuel mainly depends upon the amount of catalyst adding and type of catalysts present in the biofuel, whether it is homogenous or heterogeneous catalyst is suitable with methanol. Finally, from the analysis made from biodiesel fuel. Coconut Oil Biodiesel fuel has less emission characteristics than that of the diesel fuels.
