Performance and Emission Analysis of a Diesel Engine Fueled with Lemongrass Biodiesel with the Influence of Injector Holes

In diesel engines, injector nozzle geometry and number of holes influence on the working characteristics due to the reason that both the parameters influences the spray factors namely penetration length and droplet size. Therefore, the causes of number of hole in injector on the working feather of a diesel engine utilizing diesel and 20% Lemomgrass oil methyl ester (LGOME20) was experimentally investigated with various engine loads with respect of brake power. The injector with 3, 4 and 5 hole nozzle were used for this study. The output showed that the Nitrogen Oxides (NOx) emission and Brake Specific Fuel Consumption (BSFC), were increased, HydroCarbon (HC), Carbon monoxide (CO) and smoke opacity, emissions were diminished for LGOME20 with 4 hole and 5 hole injector when compared to LGOME20 with standard 3 hole injector.
