Bachelor/Master Thesis: Piston Ring – Liner Contact Chemistry under Methanol Contaminted Lubrication

The Institute of Machine Elements and System Development researches the fundamental structural and tribological behaviour of machine elements and depicts this in experimentally validated model descriptions. These model descriptions are used to analyse and design the functional, loss and noise behaviour of entire technical systems with a focus on drive technology. The models developed are also used to research and develop methods of model-based systems engineering as a central element of future, inductive product development processes.

The Tribology department at MSE researches the tribological behaviour of machine elements. The focus of research is on application-orientated basic research. Key topics include the interactions between the lubricant and the surfaces of the lubricated components, the wear behaviour of machine elements and the changes in lubricants caused by use. Other key topics include condition monitoring and service life prediction of machine elements.

Background:

In order to reach net zero emission goal in Europe, green energy sources need to be adapted to many engineering systems. Alternative fuels plays important role in this change. This research investigates how methanol fuel contamination alters the chemistry and mechanics of the ultra-thin boundary lubrication films (tribofilms) that protect piston rings and cylinder liners.

Various fuel-material-lubricant combinations will be tested and their tribochecmistry will be analyzed. Analyze how methanol combustion byproducts (formaldehyde, formic acid, water) influence film formation, growth, chemical composition, and mechanical stability.
