“…Surface topographies from fired engines have been analyzed in this work and have been compared with new surface measurements. As a complementary and efficient measure of wear, Picken et al 33 proposed to perform hand-made controlled scratches on the liner surface and to monitor their depth at different times. The main advantage is that the wear is measured at specific locations.…”

This paper is part of a project aiming at optimizing the cylinder-liner/piston-ring contact performance: oil consumption, friction and wear. The surface micro-geometry has a major influence on these characteristics. Classical cylinder-liners display cross-hatched patterns. Grooves modify contact pressure distributions and act as lubricant reservoirs and pipes redistributing oil. The load-carrying capacity is greatly influenced by the number of grooves and their geometry. An automatic groove geometry identification (depth, width, angle) is performed on cylinder-liner surface measurements. The surfaces were measured at two instants: new and after a fired engine test. The micro-geometry evolution is discussed.
