概要

Experiments on piston ring scuffing were conducted using a simulation test equipment of relatively large size of increased similarity with actual marine diesel engines, and a practical empirical formula was obtained. In addition, scuffing was caused to occur in practice using actual medium speed diesel engines to verify said empirical formula, and it was found that this formula was effective for judgment in the stage, of design and development.<BR>This paper suggests that the important factor that obstructs evolution of future diesel engines is piston ring scuffing based on said practical empirical formula, and it also describes the direction to be taken into the future.
