T-MAS, the Detector of Scuffing before Excessive Wear

概要

論文の詳細を見る
The Temperature Monitoring and Alarming System (T-MAS) is a unique system which can detect scuffing on the running surface of the cylinder liner of large two-stroke diesel engines before the occurrence of excessive wear. An excessive wear of cylinder liner has a very high impact on the vessel schedule and operating cost.<BR>T-MAS detects the symptom of scuffing on the surface of cylinder liner by monitoring temperature. Normally, there is enough cylinder lubricating oil on the surface of cylinder liner. When the scuffing is started on the very small local part, cylinder lubricating oil has gone by the metal-to-metal contact and combustion gas with high temperature blows on this part. At that time, the temperature behavior of this surface is unique. Therefore, ship operators can avoid the excessive wear by taking a proper countermeasure when T-MAS detects such phenomenon.
