Utilization of unattended methyl ester of paradise oil as fuel in diesel engine

Engine tests have been carried out with the aim 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 found that there was a significant reduction in smoke and hydrocarbon emissions by 33% and 22% respectively for MEPS 50 blend and 40% and 27% reductions for MEPS 100. However, there was an increase of 5% and 8% NOx emission for MEPS 50 and MEPS 100 respectively. Brake thermal efficiencies of MEPS and its diesel blends are slightly lower than that of std. diesel. From the engine analysis, it was found that the performance of MEPS and its diesel blends were similar to that of std. diesel.
