Cross hatched texture influence on the load carrying capacity of oil control rings

摘要

The optimization of the cylinder-liner/piston-ring contact performance (oil consumption, friction and wear) is the final objective of this work. The micro-geometry impacts directly the contact behavior. Cross-hatched textures are usually manufactured on cylinder liner surfaces. Grooves are often described as lubricant reservoirs and pipes redistributing oil. Grooves also change the pressure distribution and load carrying capacity.
