This paper present a study of the effects of duration of injection on emissions and combustion characteristics in a direct injection diesel engine using CFD code KIVA-3V. In this study, duration of injection was also changed from 6o to 12o CA while the injection timing is constant to evaluate the effect on DI Diesel engine performance, indicated specific fuel consumption and particulates and oxides of nitrogen emission. The obtained results indicate that the capacity of the engine reaches its maximum value and NOx and soot emissions is decreased when the duration of injection is in the range of 6o to 9o CA.
