Notes:
The laser honing technique is a new surface texturing technique. As the piston ring at thetop or lower oil attachment point works under worse lubrication condition, its wear increasesseverely, laser texturing was used to the piston ring/liner, lineary extending grooves and regulararranged dimples with predetermined parameters was well-matched with the needs of lubrication.The effects of different dimple shapes, such as sphere coronal, combined sphere coronal ,columnar,hexahedral, and trapezoidal dimples was analyzed by the theory of hydrodynamic lubrication. Itwas deduced that trapezoidal dimples are fit for only single running orientation and sphere coronaland combined sphere coronal dimples are fit for double running orientations. The experimentalresearches show that laser texturing not only can reduce the oil consumption and the cost of enginebut also can prolong its work life
