An Improved Lubrication Model between Piston Rings and Cylinder Liners with Consideration of Liner Dynamic Deformations

The friction pair of piston rings and cylinder liner is one of the most important friction couplings in an internal combustion engine. It influences engine efficiency and service life. Under the excitation of piston slaps, the dynamic deformation of cylinder liner is close to the surface roughness magnitudes, which can affect the friction and lubrication performance between the piston rings and...

Investigating the effect of nanocoating on friction loss and abrasion in the piston rings

The piston ring which prepares mechanical sealing of a combustion chamber, should have significant abrasion resistance and less friction loss, using appropriate ring coating. The coating widely used is CrN, because of its good abrasion resistance at room temperature. However, it suffers from some shortcomings, such as high abrasion rate at temperatures above 200°C and lack of self-lubricating p...

reflections on taught courses of the iranian ma program in english translation: a mixed-methods study

the issue of curriculum and syllabus evaluation and revision has been in center of attention right from when curriculum came into attention of educational institutions. thus everywhere in the world in educational institutions curricula and syllabi are evaluated and revised based on the goals, the needs, existing content, etc.. in iran any curriculum is designed in a committee of specialists and...
