摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine having a bearing shell for satisfying different requests in points of load support capacity and resistance to a dust; and a method for manufacturing these layers. SOLUTION: The internal combustion engine has the bearing shell formed of a phase of at least two sliding bearing materials mutually spatially separated, arranged on a surface of the bearing shell and having different hardness and substantially formed of a bearing layer by thermal spraying. The method includes a step of mechanically adjusting one bearing surface, a step of covering the bearing surface with a material of the bearing shell by one thermal spraying method, and a step of processing one thermal spraying layer by smooth finishing, and manufactures the bearing shell for the internal combustion engine. At least the two sliding bearing materials having different hardness, are welded in a spatially separated area as the bearing shell, and mutually contact via a mixed microstructure.

摘要： The invention relates to a cylinder crankcase made of an aluminum diecasting alloy with at least one cylinder bore which has at least one cylinder liner made of a hypereutectic aluminum/silicon alloy, in which in each case a piston is arranged so as to be axially movable, the piston comprising at least one piston ring, one piston skirt and one piston crown, the piston having, with respect to its movement relative to the piston ring, a top and a bottom dead center. The invention is characterized in that the cylinder liner ends at most 10 mm below the bottom dead center, and edge regions of the cylinder bore below the cylinder liner consist of the aluminum diecasting alloy.

摘要： Surface activation is intended to ensure that a cylinder liner can be anchored in the casting material of a light-metal crankcase with greater bonding. For surface activation, the surface of the cylinder liner is roughened mechanically. Advantageously, copper particles are also implanted into the treated surface. It is necessary to ensure that the time span between surface activation and casting-in is short. Moreover, the activated surface, as far as possible, should not be touched by hand.

摘要： Cylinder liner blank production, by cutting a continuously cast fine-grained aluminum-silicon alloy tube (80) into lengths, is new. Cylinder liner blanks of hypereutectic aluminum-silicon alloy are produced by cutting length sections of a quasi-continuous fine-grained AlSi alloy seamless tube (80) formed by continuous casting of a melt which solidifies in a fine-grained condition as a result of rapid forced cooling (40, 50) and/or shear motion of the melt, the cast strand (80) being internally shaped to the desired open cross-section and cooled, in addition to external shaping and cooling, by a core which extends through the melt to concentrically within the cast strand (80) and which is end cooled.
