The Partially Lubricated Piston Ring
Journal of Mechanical Engineering Science, 1977The discrepancy between measured and calculated oil-film thickness under a piston ring is shown to be due to oil starvation. If care is taken to keep the inlet region filled with oil, the film thickness is found to obey the theory. A simple formula is derived for predicting the degree of starvation to be expected when more than one piston ring is ...

has to maintain a gas-tight chamber for the charge during its stroke, when hot or cold, and to transmit the combustion pressure through the connecting rod to the crankshaft. The excess heat in the combustion chamber is dissipated partly by the piston to the cylinder walls, so there must be sufficient surface contact, and the piston is expected to last ...

The piston ring is one of the most important parts of a two-stroke marine diesel engine. It is lubricated by a special mode in which the lubricating oil is directly injected into the liner’s inner surface.

Effect of additives on a surface textured piston ring–cylinder liner system
Tribology - Materials, Surfaces & Interfaces, 2019Laser texturing of the surface is a known approach to improve the tribological performance of mechanical systems. Many studies focused on optimising surface texture parameters for the piston-ring cylinder liner (PRCL) system. However, little attention is

Purpose In an internal combustion engine, piston ring-cylinder liner tribo pair is one among the most critical rubbing pairs. Most of the energy produced by an internal combustion engine is dissipated as frictional losses of which major portion is ...

Tribological studies of automotive piston ring by diamond-like carbon coating
Tribology - Materials, Surfaces & Interfaces, 2019Increasing environmental awareness and demanding low energy consumption are of the top priorities for future vehicles manufacturing companies. This can be achieved by reducing wear and friction of engine components, so that its efficiency and lifetime ...
