ABSTRACT
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% 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 de-creased with an increase in the number of nozzles, at the penalty of increase in NOx emissions has been observed.
