Cylinder liner cold corrosion
WebJan 8, 2024 · The iron found in used cylinder oil samples typically exists in various forms, each one having its own particular properties. For example, metallic iron particles worn off the cylinder liner by cat fines exhibit strong ferromagnetism and may be detected. There are cold corrosion test kits to aid in this condition monitoring process. WebHigh Iron levels caused by scuffing incidents or Catalytic Fines in bunker fuels can be isolated from cold corrosion issues. Conversely, corrosion caused by sulphuric acid corrosion of the liners can be isolated from other wear mechanisms in the cylinder chamber. Major OEM's recommend a maximum cold corrosion figure of 200PPM.

WebGenerally, cold corrosion results from operating at too low an operational temperature or using oil with too low of a Base Number (BN) and Bore Polish results from over lubrication use of oils with too high of a BN. Both of these conditions result in accelerated wear and lead to liner scuffing. Increased Efficiency In Inspections Webfuels can be isolated from cold corrosion issues. Conversely, corrosion caused by sulphuric acid corrosion of the liners can be isolated from other wear mechanisms in the cylinder chamber. Major OEM’s recommend a maximum cold corrosion figure of 200PPM. Ideally this should be kept below 100PPM within the engine to maintain low wear levels.
