Investigations on performance and emission parameters of direct injection diesel engine running with Mesua ferrea oil methyl ester blends

The present study deals with the experimental analysis on performance and emission characteristics of VCR diesel engine operating through Mesua ferrea oil methyl ester (MFOME) blends at different injection operating pressures of 180 bar, 200 bar, and 220 bar. Four test fuels were used in this analysis namely diesel, MFOME10, MFOME20, and MFOME30. The conventional diesel has shown higher BTE than the leftover MFOME blends while the BSFC was also lowered for conventional diesel. Emission parameters namely CO, UHC, and smoke opacity were reduced while the CO2 and NOx were greater intended for MFOME blends than conventional diesel. The similar trend was followed at all three injection pressures and better results were noticed at an injection operating pressure of 220 bar. The performance of MFOME20 is somewhat nearer to conventional diesel and better emission concerning CO, UHC, and smoke opacity were with MFOME20.
