Oil Going-up Mechanistic Analysis for Oil Consumption Stabilization (Second Report)

- Grasp Physical Quantity of Oil Behavior in Decelerating Condition -

Abstract

In order to understand the mechanism of lubricating oil consumption (LOC) and the details of it, nowadays cylinder visualization method which can observe direct oil motion in a cylinder and analyze oil film thickness by the image analysis is used. In this study, more detailed oil transportation by the simultaneous measurement of the visualization, ring motion and the pressure of piston lands in decelerating condition is reported. Oil transportation depends on the level of inertia force and vacuum pressure influenced by the ring axial motion.
