Numerical studies on optimal design of combustion system for high-speed diesel engine, which is mainly used for power generation or ship propulsion, have been carried out to meet the target value of fuel oil consumption and IMO(International Maritime Organization) Tier2 NOx regulations. The spray visualization experiment was performed in the constant-volume high-pressure chamber to clarify the numerical results on the spray characteristics of the spray angle and penetration for medium-speed diesel engine having the same bore size. The intake/exhaust valve timing and turbocharger specifications were determined from the results of 1-D performance analysis. The nozzle configurations of the unit injector, fuel injection rate, piston bowl shape and compression ratio were determined from the results of 3-D in-cylinder combustion analysis. The intake swirl port geometry was developed from the results of 3-D flow analysis to improve the rate of fuel-air mixing and the velocity of diffusion flame for the reduction of fuel oil consumption. Finally, engine performance of the combustion system designed by numerical analysis was verified from the experimental results.
