The estimation of the loading for nozzle's guiding precision interface from diesel's fuel injector by means of CFD-modeling

The analysis of moving the fuel’s fluid stream into hydraulic tract of cylindrical guiding precision interface of the nozzle from diesel’s fuel injector is performed in application to different models of fluid dynamic (CFD). The distribution of the pressures and velocities of fuel in the interface, values of the radial force and problems of the increasing the service life of the guiding precision interface are considered and estimated by means of modeling for high (up to 120 MPa) values of the pressure of fuel injection.
