摘要：

The standard diesel engine parameters are well-suited with conventional diesel fuel operation. However optimization of engine parameters for dairy scum biodiesel operation in diesel engine is highly pronounced as dairy scum oil methyl ester (DSOME) has higher viscosity and lesser heating value when compared to petroleum diesel. In the present investigation standard engine piston bowl and nozzle hole geometry along with engine parameters (Injection pressure (IOP): 210, 220, 230 and 240 bar; Injection timing (IT): 23, 26 and 29.deg. bTDC; Compression ratio (CR): 16, 17 and 18) were modified to evaluate the diesel engine performance operated with optimized blend of DSOME-B20 among DSOME-B10, DSOME-B30 and DSOME-B100. From the experimental study it clears that modified engine with RTPBG (Re-entrant toroidal piston bowl geometry) had shown improved performance in comparison with HPBG-ME (Hemispherical piston bowl geometry-Modified engine) and DSOME-B20-SE (standard engine), which could be attributed to improved fuel atomization, reduction of fuel droplet size, increased cylinder temperature, enhanced swirl and squish (turbulent kinetic energy) during combustion.
