A casting device and a casting processes for producing a cast component in a mold in which a mold cavity is formed, and a cast component produced by means of the casting process. The casting device includes a first melt feeder, configured to receive a first molten material, a second melt feeder, configured to receive a second molten material, and a feed device configured for simultaneous or temporally independent charging of the mold cavity with the first molten material from the first melt feeder and the second molten material from the second melt feeder by means of gravity. It is provided that the feed device has at least one first outlet that can be introduced into the mold cavity and can be moved relative to the mold cavity in order to charge the mold cavity with the first molten material and/or the second molten material.

Disclosed are a cylinder liner for insert casting and a method for manufacturing the same. In particular, the cylinder liner for insert casting has cooling and warming performances suitable for functions of respective parts by imparting multiple layers having different thermal conductivity on the surface of the cylinder liner for insert casting, such that the cylinder liner can be used for vehicle cylinder blocks.

A cylinder head includes an inner structural member having a plate forming a deck face of the cylinder head and forming at least one dished cylinder roof, and a plurality of cylinder head bolt columns extending from the plate. An outer member is supported by the inner structural member and forms a cooling jacket, intake ports, and exhaust ports. Passages of the cooling jacket are lined with metal walls in contact with the composite structure of the outer member. A method of forming a cylinder head includes positioning a structural insert and a lost core insert in a tool, and injecting material into the tool to form a body surrounding the structural insert and the lost core insert thereby forming a head preform. The lost core insert is shaped to form a cooling jacket and has a lost core material generally encapsulated in a metal shell.

A cylinder liner for an engine block includes a first engine block bonding surface, and a second engine block bonding surface that provides a lower heat transfer coefficient between the cylinder liner and an adjacent engine block material than the first engine block bonding surface. The second engine block bonding surface extends a substantial portion of the axial length of the cylinder liner.

A method of forming an engine is provided. A liner is cast with an outer surface with a first texture extending circumferentially from a first end to a second end of the liner. A section of the outer surface of the liner is machined to provide a second texture extending circumferentially about the liner and spaced apart from the first end, wherein the second texture has a lower specific surface area than the first texture. An engine and a cylinder liner for the engine are provided. The liner has first and second ends with an outer surface extending therebetween. An outer surface of the liner has axial sections defining different textures to form material interfaces with the block with different thermal conductivities thereacross.

An engine has a cylinder block formed by a block material and defining at least one cylinder. The block defines a lubrication circuit with fluid passages including an inlet passage, a main oil gallery, a crankshaft bearing lubrication passage, and a piston ring lubrication passage. The fluid passages are formed by continuous metal walls in contact with and surrounded by the block material. At least one of the fluid passages is curved. A method of forming a component with an internal pressurized lubrication circuit includes positioning a lost core insert in a tool, with the insert shaped to form a lubrication circuit. The lost core insert has a lost core material generally encapsulated in a continuous metal shell, and at least one curved section. Material is provided into the tool to form a body surrounding the lost core insert thereby forming a component preform.

The invention relates to a method for producing a thermally sprayed, thin-walled cylinder liner for insertion into a cylinder crankcase and to a cylinder liner produced with said method.

An assembly, a crankcase, a reciprocating internal combustion engine, and a method for producing a reciprocating internal combustion engine facilitates engine block cleaning after casting, enables current and future residual-soiling standards to be met, and provides a solution to the challenges facing current and future high-performance engines, in particular the load zones head plate and cylinder tube, as well as potential for local improvement to properties in the crankcase in the additional load zones, namely the screw connection connecting the cylinder head and the crankshaft bearing. The assembly includes at least two cylinders and a platelike deck plate connecting them of integral design, wherein the platelike deck plate has a clearance for each cylinder and wherein the assembly can be inserted into or placed upon a crankcase of a reciprocating internal combustion engine, in that at least one coolant guideway is arranged between the cylinders.

A cylinder liner assembly for inclusion in the cylinder bore of an internal combustion engine includes a sleeve-like cylinder liner and an anti-polishing ring to scrape combustion deposits from a piston reciprocally movable along an axis line of the cylinder liner. A fire dam may axially protrude from a first liner end of the cylinder liner and may have an obliquely angled chamfer disposed therein circumscribing the axis line. To locate the anti-polishing ring proximate to the top land of the piston when at the top dead center position, the anti-polishing ring can include a cuff header disposed at the first cuff end that is generally triangular and has an angled undercut corresponding to the obliquely angled chamfer. When mated, the chamfer and angled undercut abut against each other.

Provided are casting products for cooling heating elements, the casting products including: a body made of a metal material; and a cooling pipe providing a path through which a cooling fluid flows, and being made of an aluminum alloy material, wherein the body includes a plate-shaped plate portion, protrusion extensions protruding from the plate portion and extending along the cooling pipe so that at least part of the cooling pipe is fully buried, and a cooling pin structure formed integrally with the plate portion, and the cooling pipe is formed in such a way that a first pipe thickness of the cooling pipe having a cross-sectional shape in a first direction is greater than a second pipe thickness in a second direction perpendicular to the first direction, and the first direction is in parallel to the plate portion, and the second direction is a thickness direction of the plate portion.
