Assessment of diesel engine characteristics fuelled by jatropha with tamarind seed oil biodiesel

Abstract

The present experimentation is carried out on a diesel engine using biodiesel as a fuel. The combination of lemongrass and tamarind seed methyl ester has replaced the diesel at various percentages. This investigation used three blends of biodiesels i.e. 10% of mixed methyl ester and 90% of pure diesel (B10) similarly B20, and B30. From the obtained results it was observed the enhanced brake thermal efficiency (BTE) for biodiesel blends as compared to the diesel. The blend B20 shows enhanced BTE than other samples, being around 20% higher than the diesel. The biodiesel blends show a reduction in HC and CO emissions and enhancement in CO2 and NOX emissions than the diesel. The highest heat release rate observed for B20 at a crank angle of 355° is 68.77 J/deg.
