...Peijian Guo; Jiujun Xu; Zhijun Yan; Ruoxuan Huang The wear reliability assessment plays a critical role in evaluating product quality for piston ring-cylinder liner (PRCL) components. In practice, the wear data of components is discrete and sparse, which makes it difficult to evaluate the wear...

... a hypereutectic Al–Si cylinder liner specimen against the chrome-coated piston ring as the counter specimen. The experiments were performed to mimic the engine’s condition under a boundary layer lubrication regime. The type A and type B uncertainty components of the tribosystem, such as uncertainty involved...

...Vikram Kumar; Sujeet Kumar Sinha; Avinash Kumar Agarwal The main objective of this investigation is the evaluation of the performance of hard diamond-like-carbon (DLC) or tungsten carbide (WC) and soft (epoxy composite) dual-coatings on the internal combustion (IC) engine piston rings...

...V. Dunaevsky; J. Rudzitis This technical brief clarifies origins of the piston ring conformability bounds presented by Dunaevsky (1990, Tribol. Trans. 33(1), pp. 33–40) and provides their correct expression. The subject has strong practical significance in the field of piston engines...

...Y. Kligerman, Mem. ASME; I. Etsion, Fellow ASME; A. Shinkarenko An analytical model is developed to study the potential use of partial laser surface texturing (LST) for reducing the friction between a piston ring and cylinder liner. The hydrodynamic pressure distribution and the time-dependent...
