摘要：

This article presents importance of the injector nozzle geometry for performance and durability of diesel fuel system, quality of fuel spray and in-cylinder work mixture formation. Reviewed ways to improve its hydraulic characteristics. As prototype for investigation has used injector nozzle of the high-speed diesel 4DTNA1. The estimated volumetric models of the injector nozzle with two different flowing channels geometry was made. Got the results of the fuel flow modeling by CFD calculation. Carried out analysis of the diesel flow parameters in both geometries with searching ways to reduce hydraulic loses and cavitation erosion influence.
