Performance Characteristics of a Diesel Engine with Mustard-Honge Biodiesel

ABSTRACT The Increased rate of energy consumption around the world due to industrialization and modernization has been the major cause for the drastic decline in the fossil fuel. The drastic rate of depletion of fossil fuel could overcome by good alternative, that should also meet the demand of future energy requirement. In this context, biodiesel was found to be one of the best alternatives to fossil fuel. Which has the characteristics almost nearer to the conventional diesel fuel. Though there are different resources, from which Biodiesel can be extracted, yet for the present work, a Biodiesel sample has been extracted from Honge and Mustard oils in 1:1 ratio, by means of the transesterification process. 2% of ethanol is added to enhance the ignition quality. Three different samples are produced as B10, B20, and B30 when biodiesel is blended with diesel at three different proportions (10%, 20%, and 30%). These samples are applied to a 4S single cylinder diesel engine of 3.67kW @1500 RPM. The above samples of biodiesel are tested on the engine at different injection pressures of 180bar, 200bar, and 220bar respectively. The performance characteristics include BSFC and BTE are studied for the said CI engine and are found almost nearer to the values of conventional diesel as fuel, at an injection pressure of 180bar. Out of the three mentioned pressures, 200bar for the sample B10 found to be an optimal, irrespective of efficiency and economy. Further, the samples are investigated for emissions characteristics at the mentioned injection pressures. The sample B10 is found showing optimum emissions characteristics at a 200bar injection pressure compared to the rest two samples.
