摘要
利用分形几何的基本原理对柴油机燃油喷注表面特性进行了研究．在对燃油喷注轮廓分形维实际测量和分析的基础上，提出将其轮廓线的分形维作为除贯穿度和喷雾锥角之外的又一特征参数，对燃油喷注特性作定量的描述．
In this paper, the characteristics of fuel spray surface of diesel en-gine is studied with the help of fractal geometry, On the basis of the measure-ment and analysis of fractal dimension of fuel spray profile, the authors put for-ward that it may be regarded as another parameter in addition to penetration and angle of spray cone, which may be used to describe the characteristics of fuel spray in detail.
