Methods of Preparing Internal Combustion Engine Cylinder Bore Surfaces for Frictional Improvement

Frictional losses between the piston rings to cylinder bore surface is one of the major sources of mechanical losses in an internal combustion engine (ICE). Traditional plateau honing produces a relatively rough cylinder bore surface with many valleys for oil retention and plateau surfaces that are...
