The performance and emissions characters of diesel engine behavior depend
largely on several criteria, fuel injection nozzle plays a vital role in the
proper combustion of diesel engines. This research analyzes the impact of a
nozzle hole configuration on the features of a biodiesel-fuelled diesel
engine. Therefore, the causes are dependent on the modification that the
nozzle hole was selected from three-hole and five-hole nozzles, while the
engine characteristics of the lemongrass biodiesel blend with diesel were
examined. Lemongrass Biodiesel with 20 percent blend (LGB B20) has been
investigated experimentally with different engine loads with respect to
brake power, three hole, and five-hole nozzles. The experimental
investigation showed an improvement in peak i.e. highest heat release rate
of 12.5% for three and five-hole nozzle and brake specific fuel consumption
of 15% is increased in single hole nozzle and it is observed it?s diminished
in three and five holed nozzle. Further, the brake thermal efficiency is
increased in the five-hole nozzle in comparison to the three hole nozzle at
full load condition. Furthermore emission characteristics like HC, CO, and
smoke are decreased with an increase in the number of nozzles, at the
penalty of increase in NOx emissions has been observed.
