Abstract
An experimental study has been conducted on the effect of alumina nanoparticles in a DICI (Direct Injection Compression Ignition) engine using cymbopogon flexuosus (lemongrass oil) as fuel. Lemongrass oil (LGO) is extracted from the steam distillation method. This fuel may also be more suitable for diesel engines as an alternate fuel without any transesterification process and engine modification. In this study, three fuels (LGO25, LGO25+ALU50 ppm and LGO25+ALU100 ppm) were tested in a single-cylinder, four-stroke and naturally aspirated diesel engine. From the experimental analysis, it was found that BSFC decreased with an increase in BTE using alumina nanoparticles. The cylinder pressure and heat release rate are higher by 1.66% at LGO25+ALU 50 ppm and 3.7% at LGO25+ALU 100 ppm than LGO25. In the case of emission study, CO, HC and smoke emissions decreased by 16.67% and 25.79%, 5.9% and 12.83%, and 18.94% and 24.7% at LGO25+ALU50 ppm and LGO25+ALU100 ppm concentrations, respectively. NOx emission is increased by 4.95% and 8.27% for LGO25 with 50 ppm and 100 ppm respectively than LGO25.
