Abstract: Biodiesel is made by combining alcohol (usually methanol) with vegetable oil, animal fat, or recycled cooking grease. Among them, much different kind of fuels can be found: bio ethanol, bio butanol, biodiesel, vegetable oils, bio methanol, pyrolysis oils, biogas, and bio hydrogen. This thesis work is focused on the production of biodiesel, which can be used in diesel engines as a substitute for normal diesel. However, vegetable oils are preferred because they tend to be liquid at room temperature, and emit fewer pollutants. This work is carried out with the help of biodiesel made from Niger Seed Oil and Milk Scum Oil with methyl ester which meets the international standards. The performance and emission test were carried out in a single cylinder water cooled direct injection compression ignition engine. The hydrocarbon, carbon oxides and dioxide emissions were found to be less than that of neat diesel fuel except nitrogen oxides. Brake thermal efficiency of biodiesel and its blends was found to be less than diesel fuel. However, exhaust gas temperature, brake specific fuel consumption for biodiesel and its blends were found to be higher than that of diesel fuel.
