Abstract: The engine was tested with biodiesel blends for various loads and the speed is maintained constant at 1500 rpm to study the improvement of performance. Experimental result shows that brake thermal efficiency (BTE) increased upto14.7%, brake specific fuel consumption (BSFC) decreased up to 8.7%. The exhaust gas temperature 1310C (pure diesel) reduced to 112 0C at zero break power, whereas exhaust gas temperature increased from 548 0C to 571 0C at maximum load due to faster burning of blended fuels. The mean effective pressure (MNEP) at different break power with an engine speed of 1500 rpm found as 74.9 bar for blends and 68.8 bar for pure diesel. Heat release rate found 162.1 KJ/m3K for D50 E40 blend and 121.2 KJ/m3K for pure diesel at maximum break power. Longer ignition delay and shorter combustion duration are found with all blends than pure Diesel fuel. The concentrations of NOx, CO, CO2, PM and HC gases reduced to 0.036% in exhaust emission for biodiesel blends. Also, the smoke density is drastically reduced to 36 [HSU-Hartridge smoke units] than that of Diesel fuel. The oxygen concentration, fuel distribution, latent heat of vaporization, combustion temperature, ignition delay and cetane number have improved performance, combustion and reduced exhaust gas emissions. This study has been used for the applications in automotive engines.
