(FR) CHEMISE DE CYLINDRE D'UN MOTEUR ALTERNATIF
Abstract: front page image
(EN)A cylinder liner (1) of a reciprocating engine, the cylinder liner (2) having an inner surface (3) acting as a running surface (4) for piston rings (5), which running surface (4) comprises an upper portion (U) and a lower portion (L). The upper portion (U)includes at least a top dead centre region of a topmost piston ring (5). Only the upper portion (U) of the running surface (4) is provided with a coating(7) of metal matrix composite reinforced with ceramic particles.
