摘　　要：采用高分辨率单反数码照相机和马尔文激光粒度分析仪分别在20MPa、24MPa和28MPa喷油压力下对纯柴油的喷雾特性进行了试验研究。结果表明随着喷油压力的逐渐增大,燃油喷雾锥角逐渐增大,索特平均直径逐渐减小,说明增大喷油压力可以提高燃油的雾化质量。The spray characteristics of pure diesel were tested at high pressure high resolution digital camera and Spraytec laser particle size analyzer at 20MPa, 24MPa and 28MPa injection pressure respectively. The results show that with the increase of the injection pressure, the taper angle of the fuel spray increases gradually, and the average diameter of the Sauter decreases gradually, which indicates that increasing the fuel injection pressure can improve the atomization quality of the fuel.
