Further Developments In Cylinder Bore Finishes

This paper describes a cylinder plateau bore finish derived from a production process. The resulting surface is clean and free from ragged honing lines. Consistency in production is achieved as a result of the nonsensitivity of the process. Details of honing sticks, production process, control capability, and engine test results are discussed.

Bore areas have been analyzed by viewing “Stereoscan” shots of the honed surface.
