| Abstract: | In this experimental analysis, the impacts of altering the injection nozzle geometry on the performance parameters of a compression ignition (CI) engine were explored. The injection nozzle geometry of the standard engine with three holes of 0.24 mm diameter was replaced by a 6‐hole injector having 0.20 mm diameter. The modified engine was tested by a blend of 20 volume per cent of jatropha biodiesel (JOME20) in diesel. Considering the small size of the injector orifice, the injection pressure was raised to 240 bar from the standard pressure, and the injection timing was adjusted to 21° before Top Dead Center (bTDC) from the normal. The test findings revealed that the modified engine showed an enhancement in "Brake Specific Fuel Consumption (BSFC)" and "Brake Thermal Efficiency (BTE)." Notable improvements in the decrease of emissions have been observed. However, the enhanced fuel‐air mixing and high combustion temperature increased the oxides of nitrogen (NOx) emissions. The modification of the injection nozzle geometry showed improvements in BSFC, BTE, and a reduction in emissions, but with a trade‐off of increased NOx emissions, highlighting the need for further optimization.
