Abstract
Increasing energy demands and various environmental stringent laws are the factors which give thrust area to the scientist to develop clean and green energy for future and sustainable developments. Biofuel (Biodiesel) seems like an alternative that can meet several energy requirements. Biodiesel from Non-edible vegetable oil is getting more attention day by day compared to edible vegetable oil. Jatropha Biodiesel is promoted as a sustainable and renewable source of energy that can be used as a replacement to diesel fuel in the compression ignition engine. The present research is carried out to find the suitability and sustainability of Jatropha biodiesel in the diesel engine. The trans-esterification process is used for the production of Jatropha oil biodiesel and different samples of biodiesel are prepared. Physio-chemical properties of fuels, its sustainability, performance, and emissions characteristics of the CI engine are experimentally investigated, followed by energy and cost analysis to explore the operational and economic feasibility. Fuel properties determined in this study conform to the ASTM D6751 standard. The outcomes of the study indicate that the viscosity of different blends of biofuel is close to pure diesel. With the increase in the percentage of prepared biodiesel in fuel, specific fuel consumption increased whereas, the thermal efficiency of the engine falls. The maximum thermal efficiency of the engine is found to be 29.8% and 19.2% for pure diesel and biodiesel respectively. There is an improvement seen in the hydrocarbon emissions but with the rise in percentage of biodiesel in different composition of blends, NOx emission increases. Results conclude that the blend of a 10–20% of Jatropha biodiesel with mineral diesel (B10 and B20) is suitable to use as fuel in CI engines.
