Now a days increasing in prices and depletion of fossil fuels, creates very necessary to find out an alternative fuel (biodiesel) from renewable natural resources. This paper deals with the transesterification of animal fat (dairy scum oil) to obtain Fatty Acid Methyl Ester (FAME) or biodiesel in presence of calcium oxide catalyst at 65°C. The properties of produced biodiesels and their blend for different ratios (B10, B20, B30 and B100) are comparable with properties of diesel and ASTM biodiesel standards. Tests have been conducted on CI engine for different blends of biodiesel with standard diesel, at an engine speed of 1500 rpm, fixed compression ratio 17.5, fixed injection pressure of 200bar and varying brake power. The performance parameters includes brake thermal efficiency, brake specific fuel consumption, Exhaust gas temperature and emissions parameters as Carbon monoxide (CO), Carbon dioxide (CO2), Hydrocarbon (HC) and Oxides of nitrogen (NOx) varying against Brake Power (BP). |
