The objective of this study was to evaluate the various properties of biodiesel and optimize the biodiesel blend with conventional diesel fuel. Biodiesel fuel is a clean-burning fuel made from natural renewable sources such as free fatty acid of rice bran vegetable oil. Biodiesel operates in compression ignition engines similar to diesel fuel. It can be burnt in any standard unmodified diesel engine blended with 0% to 100% biodiesel with diesel. Free fatty acid of rice bran oil can be converted into biodiesel fuel as methyl ester by transesterification. Experimental investigations have been carried out using biodiesel as an alternative fuel in single cylinder, compression ignition engine under varying operating conditions. Various parameters such as brake power, specific fuel consumption, exhaust temperature and emissions during combustion process under varying operating conditions with diesel, biodiesel, blends of biodiesel were studied. Various properties of the biodiesel thus developed were evaluated according to ASTM and compared in relation to that of conventional diesel. These tests for biodiesel and diesel oil include density, viscosity, flash point, aniline point/cetane number and calorific value, etc. The prepared biodiesel from free fatty acid of rice bran oil was used for short-term engine performance test with different blends with diesel. It was found that 20 percent blend of biodiesel gave the best performance amongst all blends. There was a net advantage of 3 percent in peak thermal efficiency, substantial reduction in smoke opacity values and 3 to 4 percent increase in NOx. This blend was chosen for long-term test on the CI engine. The engine operating on optimum biodiesel blend showed substantial improved behavior. A series of engine test provide adequate and relevant information that the biodiesel can be used as an alternative, environmental friendly fuel in existing diesel engines without modification in the engine hardware.
