Characterization of engine liner topography

Abstract

The characterization of engine liner topography has been a topic of considerable research in manufacturing, tribology, surface metrology and auto-mobile engineering for the past 30 years. It is believed that an idle surface topography would result in a short running-in stage, low oil consumption, low harmful emissions, prolonged engine life and good engine performance. To achieve these objectives a plateau-shaped feature which possesses truncated peaks, deep valleys and a crossed striation pattern is required for the surface topography of engine liners (cylinder liner).
