The piston remains one of the most challenging components to successfully design, and is certainly quite critical to the performance and durability of the engine. The root of the challenge lies in the piston’s role as the moving combustion chamber wall.

Lubrication Science, 2020
In current researches on the lubrication of engine piston ring, some were based on a hypothesis that the piston ring is on a flooded lubrication status. Although some others belong to the starved lubrication analysis, the one‐dimensional model, a certain

Investigation of Scuffing Resistance of Piston Rings Run against Piston Ring Grooves
Tribology Transactions, 2008The hot scuffing phenomenon of a piston ring in a ring groove is one of the important failure mechanisms in an automotive engine. The dynamic motion of a piston ring against the ring groove is very complicated. Five motions are usually involved, including radial sliding, circumferential sliding, impacting, rocking, and tilting.

Piston Ring Lubrication—Part 1: The Historical Development of Piston Ring Technology
Journal of Lubrication Technology, 1982The history of the piston seal may be traced far beyond the Industrial Revolution, for the problems inherent in sealing a moving piston within a cylinder were well known to the early Greek and Roman engineers. Substantial progress in piston sealing technology was not made, however, until the 17th and 18th centuries, and it was the advent of the steam ...

Biodegradation of PEEK Piston Rings
Polymer Degradation and Stability, 2021Abstract Polyether ether ketone (PEEK) is considered a high performance thermoplastic with excellent mechanical, chemical, and thermal properties. It is generally believed that this material is chemically and biologically inert, and is used for various biomedical and industrial applications, especially in the form of fiber reinforced polymeric ...

Industrial Lubrication and Tribology, 1978
In this paper, wear of the cylinder is taken to mean not only wear of the liner but of the piston ring assembly also, since usually, though not always, the wear of the one is closely related to that of the other. The wear process may be corrosive, abrasive or frictional, and it is likely that all three processes occur together to varying extents ...

On the optimum design of piston rings
Journal of Optimization Theory and Applications, 1980We study a family of control problems that arise in the design of dynamically loaded bearings which have a minimum power loss; in particular, we study the design of piston rings with minimum parasitic power loss.
