Development of a chemically compatible, low viscose and low ash oil for internal combustion engines containing parts with friction-reducing coatings

Résumé des résultats (Abstract) (Allemand)

The aim of the project is to develop of a chemically compatible, low viscous and low ash oil for internal combustion engines containing parts with friction-reducing coatings. Functional surface coatings have recently been intensively investigated and are expected to enter the market in internal combustion engines within the next years due to fuel economy requirements or for engine performance reasons. It is expected that losses due to mixed friction in the use of functional coatings in internal combustion engines can be significantly reduced. However, the tribological, chemical and physical properties of functional surfaces are fundamentally different from those of conventional, iron-metallic surfaces. The new engine oil must not only comply with the existing OEM performance requirements but also prolong the life-time of the coating.
