提出了一种利用滤光氙灯和摄像机对活塞表面油膜的分布和行为进行详细观察的荧光图像诊断方法。在理论上考虑了荧光染料和油与荧光染料的吸收光谱后，选择了具有合适光谱特性的光源来测量油膜厚度。对曲面的测量结果进行了简单的修正和标定。该系统的使用保证了对活塞裙和活塞环上油膜分布和行为的定量测量，具有一定的实际应用价值。
A fluorescence image diagnostic method in which a filtered Xe-flash lamp and a video camera are used has been developed to observe the distribution and behavior of oil film on a piston surface in detail. A light source with appropriate spectrum characteristics for measurement of the thickness of thin oil films was employed after theoretical consideration of the absorption spectrum of the fluorescent dye and the oil with the fluorescent dye. A simple correction for measurement results obtained for a curved surface and calibration were carried out. The use of this system ensures that the distribution and behavior of oil film on the piston skirt and piston rings can be quantitatively measured, and the system is shown to have practical applications.
