  • When there is a certain inlet chamfer and nozzle taper at the inlet of the nozzle orifice passage, the efficiency of the engine can be further improved by improving the fuel atomization effect of the nozzle. In this paper, soft fluid abrasive is used to process the orifice channel, so that the orifice channel inlet has a certain inlet chamfer and orifice taper. The test results show that under the inlet pressure of 5 MPa and 8 MPa, the average particle size is 5 μm. After 800 s of processing with 25% soft abrasive, the measured radius of curvature of the orifice inlet chamfer is 0.018 mm and 0.01 mm respectively, and the taper of the orifice channel is 1° and 3°. Under different inlet pressures, this paper analyzes the flow characteristics of soft fluid abrasive in the orifice channel through the polyflow software. At the same time, the error between simulation and test results is found to be within the allowable range, which proves the reliability of numerical analysis.
