Abstract
This paper presents the results of three dimensional simulation using CFD on a diesel engine spray. In this study the effect of some spray parameters like injection timing, break-up time and other important factors that control the diesel combustion such as swirl ratio, piston wall temperature , and initial charge temperature were investigated.
The result of the simulation shows that the formation of exhaust gas emission, which is influenced by injection timing, break-up time, swirl ratio, can be predicted qualitatively. The influence of piston wall temperature on Total Hydrocarbon
(THC) emission concentration still could not be predicted properly.
