SULZER RTA—58—68—76—64 TYPE DIESEL ENGINES S. BULLETIN — LOSS OF MATERIAL ON PISTON CROWNS DUE TO HIGH TEMPERATURE CORROSION AND EROSION

The loss of the material occurring on piston crowns which is actually more generally known as piston crown "burn-off will be discussed in this Service Bulletin. Introduction; Loss of material on piston crowns; Countermeasures to minimize the loss of material; Piston cooling water system; Conclusion; Service bulletins published for large bore RTA-type engines. The chemical elements Sulphur, Sodium & Vanadium commonly contained in the HFO, i.e. heavy fuel oil, burned in the two-stroke diesel engines are to be paid particular attention and deserve special consideration with regard to corrosive deposits which subsequently cause the material loss...
