Many countries including India whose economy is very expeditiously incrementing have very high consumption of mineral diesel in wide variety of applications. With the fervently growing economy, demand is withal going up sharply which is resulting in incremented level of vehicular traffic and is the main reason for environmental pollution compared to other sectors. To cope up with the supply and authoritatively mandate, to keep pace with the time and minimize pollution levels we have to ascertain certain alternative resources in lieu of diesel. Alcohols (especially ethanol) are a felicitous renewable fuel because it can be facilely derived from different vegetative crops. The present experimental work is carried out on a Kirloskar make 3.5 KW constant speed (2000 rpm) diesel engine. All the tests were conducted on prepared fuel blends and exhaust emissions mainly carbon mono-oxide (CO), carbon dioxide (CO2), unburnt hydrocarbons (UHC), NOx and O2 emissions were analyzed and recorded at different loads. The study demonstrates that emulsified fuel blend E10S5D85 and E15S10D75 of 195 proof ethanol may be utilized for this engine in lieu of diesel which may result in 12 to 20% supersession of diesel emanated pollution levels these days caused by conveyances. The emulsified fuel blend E15S10D75 has shown lowest emission of CO at all applied load conditions as compared to diesel as well as other emulsions. The fuel blend E10S5D85 shows minimum emission of unburned hydrocarbons and insinuate better than diesel from UHC emission perspective at proximately all the loads. The emission of NOx from the exhaust of engine was found lower on all the emulsified fuel blends then diesel. It is pellucid that NOx emissions were on lower side for emulsified fuel than diesel.
