An Experimental Investigation of Unattended Methyl Ester of Paradise Oil as Fuel in Diesel Engine

Engine tests have been executed with the intention of obtaining the performance, emission and combustion characteristics of a diesel engine running on methyl ester of paradise oil (MEPS) and its diesel blends. From the emission analysis it was observed that there has been a significant reduction in smoke and hydrocarbon emissions by way of 35 % and 25 % respectively for MEPS 55 % blend and 45 % and 30 % reduction for MEPS 100. But, there has been an increase of 6 % and 9 % NOx emission for MEPS 55 and MEPS 100 respectively. Brake thermal efficiencies of MEPS and its diesel blends are slightly decrease than that of std. diesel. From the engine analysis, it was found that the overall performance of MEPS and its diesel blends had been just like that of std. diesel.
