In recent years CFD calculation has been successfully used for mixture formation, fluid flow, combustion and pollutant formation investigations in diesel engines. Numerical simulation was carried out to investigate the effect fuel spray characteristics in marine medium speed diesel engine – Sulzer 6A20/24D. KIVA-3V code with a fuel spray model adopted for simulation atomization and combustion process. The fuel injection nozzle and other components of the engine were exchanged for combustion improvement. For better understanding, calculation and experimental test, all results are compared. Hence, standard marine engine test cycles performed to asses basic parameters caused by injection equipment retrofitting. Cylinder pressure, exhaust emission histories for full load range of the engine experimentally established.
