• In order to improve the performance of 16 V280 diesel engine, the three-dimensional numerical models of the flow field in the nozzle which belongs to the injection system was built, and different detailed flow structures was captured under different pressure conditions. Through the analysis of the flow field, the unsuitable position of the nozzle was located, and the methods which combine CAD/CAM/CFD was applicated to optimize the structure of the nozzle. The analysis results indicate that with the increase of the injection pressure; the flow turbulence intensity increase; the more energy get lost, which caused by turbulence; the coefficient of flow decrease. After the spray nozzle structure was changed into sphere pin valve, the current capacity under the same level of injection pressure was improved greatly.
