Ramesh Babu Nallamothu, Geleta Fekadu, & Prof B.V. Appa Rao

The rapid depletion of petroleum fuels and ever increasing price of them has led to an intensive search for alternative fuels. Biofuels being renewable and ecofriendly are attracting growing interest around the world. Ethanol (C2H5OH), an alcohol found to be a promising alternative fuel for gasoline engine. Ethanol is an attractive alternative fuel and blends can be used as fuel in order to substitute some part of gasoline. In this research work, procedures of measuring fuels have been used to blend the ethanol produced from sugar cane with gasoline and base fuels used for the experiment. Properties of ethanol-gasoline blended and base fuel were first examined by the standard ASTM test methods D86, D130, ES626:2008 (ANNEXB), ES640:2001 (ANNEXA), D323, D1298 and fuel was blended in different volume rates E0, E5 and E10. Moreover, the experimental comparative performance evaluation are tested and evaluated at 8:1 compression ratios. The performance and exhaust emission were carried out on gasoline engines by using TD43F variable compression engine test rig and Exhaust gas analyzer 5000 and the following test results were summarized. Best performance with maximum reduction is 2.9% Pb is obtained for all samples for the compression ratio of 8:1 at speed of 2000 rpm. Blending increases ηb for compression ratio of 8:1. Compression ratio of 8:1 is recommended to use E10.
