Biodiesel Development and Analysis of Biodiesel - Diesel Blend in C.I Engine

Energy consumption is rapidly increasing due to population growth, higher standard of living and increased production. Significant amounts of energy resources are being consumed by the transportation sector leading to the fast depletion of fossil fuels and environmental pollution. Biodiesel is one of the technically and economically feasible options to tackle the aforesaid problems. In this research work biodiesel will be produced by trans-esterification of crude Rice Bran Oil (RBO).And the analysis of C.I engine will be done by using the diesel fuel and also by utilizing the blend of biodiesel –diesel .Oil extracted from the inner husk of rice, termed Rice Bran Oil (RBO) promises to be a low-cost, renewable substitute for petroleum-derived diesel as a compression ignition (CI) engine fuel. While rice is a major crop in India, RBO is underutilized. As an oxygenated fuel, RBO reduces emission of pollutants like CO and unburnt hydrocarbon (UBHC) by supplying additional oxygen from the fuel. The specific objective of this study is to analyse the performance, and emission characteristics of RBO and its blends with diesel. Results showed that biodiesel obtained under the optimum conditions has comparable properties to substitute mineral Diesel and is found suitable to use as a substitute fuel in the C.I engine asits fuel consumption rate, Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE) is very close to that of conventional diesel fuel.
