Positive Effect of Periodic Micropatterns on Compression Ring Friction Open
Internal combustion engines are increasingly regulated in regard to efficiency and environmental impact, which requires advanced optimization strategies of engine components. The contact between the top ring and the cylinder liner is criti…

Combined experimental and simulative approach for friction loss optimization of DLC coated piston rings Open
Piston rings cause significant friction losses within internal combustion engines. Especially the first compression ring, which is pressed onto the liner by high cylinder pressure, contributes significantly to the total friction loss of th…

Friction Response of Piston Rings for Application-like Starvation and Benefit of Amorphous Carbon Coatings Open
The oil supply at the interface between the top ring and the cylinder liner (TRCL) plays a major role in an internal combustion engines efficiency. In particular, the interface forms a trade-off between the serving of enough lubricant for …
