Wear assessment model for cylinder liner of internal combustion engine under fuzzy uncertainty
Mechanics & Industry, 2021 The wear of the piston ring-cylinder system is inevitable in the operation of the internal combustion engines (ICEs). If wear exceeds the maximum, the piston ring-cylinder system will be failure.

Development of Hydrogen-Free Diamond-Like Carbon Coating for Piston Rings
Tribology Online, 2017 The first piston ring application of a hydrogen-free diamond-like carbon (H-free DLC) coating to a mass-production gasoline engine reduces friction. It is found that the friction reduction effect between the cylinder bore and piston is 18%.

Numerical experiments on vortex ring formation [PDF]
, 2001 Numerical simulations are used to study the formation of vortex rings that are generated by applying a non-conservative force of long duration, simulating experimental vortex ring generation with large stroke ratio. For sufficiently long-duration forces,
