- Summary:
- To elucidate the behavior of oil film on the piston land, the visualization experiments around the piston using an optical engine with a glass liner was conducted. The photochromic visualization technique was successfully applied. The oil film above the top ring gap moved toward the piston head under each throttle condition. The oil film velocity in each engine stroke was successfully calculated from the image processing, and it was confirmed that the direction of movement and the velocity is different with the throttle condition and the engine stroke. The rapid transport of oil film on the 2nd land under the engine brake like condition was captured and it was supposed that this type of oil transport phenomena is the cause of high oil consumption under engine brake condition
