MODEL OF DEPOSIT FORMATION ON DIESEL ENGINE PISTONS

EIN MODEL DER ABLAGERUNGSBILDUNG AM DIESELMOTORKOLBEN

In contrast to the well-known chemistry of deposit formation little is known about mechanical and physical factors governing these reactions. Several observations such as bulk oil oxidation in relation to piston temperatures, depletion of alkaline additives, cylinder wall drying of crankcase oil and the mechanism of oil consumption lead to the conclusion that in a running engine, there must exist an intensive oil circulation between the piston-cylinder zone and the oil sump. Based on this conception a more detailed description of phenomena leading to deposit formation is possible, showing more concrete terms of lubrication requirements and the possibility to reduce these requirements by means of constructive measures.
