摘要：

This paper explores the possibility of utilizing bioethanol obtained from Madhuca Indica flower as an alternative fuel in a direct injection (DI) diesel engine. Three different percentages of bioethanol (5%, 10%, and 15%) on volume basis were emulsified with diesel proportionality with the help of a surfactant. The emulsions were designated as BMDE5, BMDE10, and BMDE15 where the numeric value refers to the percentage of bioethanol. The emulsions were tested as fuels in a single cylinder, four stroke, and air cooled DI diesel engine developing a power of 4.4 kW at 1500 rpm. Results indicated that the bioethanol-diesel emulsions exhibited a longer ignition delay by about 2.2 degrees CA than that of diesel operation at full load. Overall, the nitric oxide (NO) and smoke emissions were found to be lesser by about 4% and 20%, respectively, with the bioethanol-diesel emulsions compared to that of diesel operation at full load. The BMDE5 emulsion gave a better performance and lower emissions compared to that of BMDE10 and BMDE15. It is suggested that the bioethanol produced from Madhuca Indica flower can be used as a potential alternative fuel replacing 5% of petroleum diesel.
