概要:

application/pdf<br />Journal Article<br />To reduce friction loss in automotive reciprocating engine, it is required to know the lubricant oil film behavior. In the present study, a laser-induced fluorescence (LIF) and a particle image velocimetry (PIV) were applied to measure the oil film thickness and its velocity, independently. A model engine with a quartz glass cylinder was used. Using Rhodamine B, a linear relationship between oil film thickness and … fluorescence intensity can be obtained in the range of 0 to 150μm. The LIF measurements were performed under the 300 rpm of mortaring condition. The range of oil film thickness was from 10 to 25 μm on the piston rings. The crank angle variation of oil film thickness was demonstrated successfully. The PIV measurements were also carried out under the motoring speed of 100 rpm. The velocity vector map was obtained in the slit of piston ring. The oil velocity was almost the same as the piston speed near the oil ring. Velocity profiles in the slit were visualized according to the crank angle positions. The results suggested the possibility to analyze the oil film behavior under the combination of the LIF and the PIV measurements. 続きを見る
