Abstract
A newly developed fluorescent diagnostic system can measure the oil film thickness distribution through two-dimensional images with high sensitivity and quick response. This system consists of a filtered Xe-flash lamp, a filtered charge-coupled-device video camera, a personal-computer-based signal analyzer and lubricating oil with the fluorescent dye added. We have installed the system in a single cylinder research engine and measured the oil film thickness distribution around the piston under various operating conditions. One example of the results is that an oil spout from a gap in the first compression ring, which agrees with the measured oil consumption rate of the engine, was clearly observed at high engine speed.
