    摘要: Gegenstand der Erfindung ist ein Zylinder-Kurbelgehäuse aus einer Aluminium-Legierung. Die Zylinder sind mit Zylinderlaufbuchsen versehen. Während das Gehäuse aus einer preisgünstigen Aluminium-Legierung mit 3% - 12% Silizium und 3% - 5% Kupfer, z.B. G-AISi9Cu3 besteht, werden die Zylinderlaufbuchsen aus einer übereutektischen Al-Legierung, z.B. AISi17Cu4Mg hergestellt.

    摘要: The invention relates to a cylinder crankcase (1) for an internal combustion engine, into which crankcase a one-piece cylinder jacket system (9) is diecast, said system comprising at least two cylinder jackets (5, 6, 7) that are arranged in a row and that are interconnected via webs (2, 3, 4). The aim of the invention is to provide a cylinder crankcase which can be produced at low cost and which comprises a cylinder jacket system that can be subjected to high thermal and mechanical stresses. According to the invention, a lateral face of the cylinder jacket system (9) has a rough structure and is surrounded by a diecast outer casing (26). Respective coolant passages (14, 15, 16) having openings (31, 32) for supplying and discharging the coolant are formed into the webs (2, 3, 4), at least one opening (32) extending through the outer casing (26) into the recess (25) for the water cooling jacket.

    摘要: A piston for an internal combustion engine of an automotive vehicle. The piston has a piston ring and a piston skirt section each of which has a sliding section in slidable contact with a cylinder bore section of a cylinder block in presence of a lubricating oil. The cylinder bore section is formed of eutectic or hyper-eutectic aluminum alloy. Additionally, a hard carbon thin film is coated on the sliding section of the piston and contains hydrogen atom in an amount of not more than 1 atomic %. Here, the lubricating oil contains at least one selected from the group consisting of ashless fatty acid ester friction modifier, ashless aliphatic amine friction modifier, polybutenyl succinimide, derivative of polybutenyl succinimide, zinc dithiophosphate, and derivative of zinc dithiophosphate.
