Abstract: An engine has a cylinder block with a deck face and at least one cylinder liner with a cylinder axis. The block has a first fluid jacket about the liner, a second fluid jacket about the liner, and a third fluid jacket about the liner. The first, second, and third fluid jackets are fluidly independent from one another and spaced apart from one another along the cylinder axis. A method for forming the engine includes using an insert to provide each of the fluid jackets. The insert has a lost core material surrounded by a metal shell.

Abstract: A wire feed control system includes an anti-twist mechanism and a controller programmed to operate the anti-twist mechanism, responsive to a measured degree of twist of a wire on a trajectory between a feed for the wire and a plasma transfer wire arc (PTWA) torch, to maintain the degree of twist within a predetermined range defined by natural rotation introduced to the wire by the PTWA torch.

Abstract: Oil pumps having wear-resistant coatings applied thereto and methods of applying the coatings are disclosed. The oil pump may include an aluminum housing that defines a cavity. A steel rotor may be disposed within the cavity and configured to rotate therein such that a portion of the steel rotor contacts the aluminum housing. A metal coating (e.g., steel) may cover at least a portion of the aluminum housing in a region that is configured to be contacted by the steel rotor. An integrated oil pump and engine cover is disclosed including an aluminum body having a peripheral wall defining a cavity. The peripheral wall may form a portion of the oil pump housing and the cavity may receive a steel rotor. A wear-resistant coating (e.g., steel) may cover at least a portion of the peripheral wall in a region that is configured to be contacted by the steel rotor.

Abstract: A tool and a method of forming an engine using the tool are provided. The tool includes an insert and at least one die. The insert is formed by forming an interbore passage between first and second siamesed cylinder liners, casting a lost core, and then casting a metal shell. The insert is positioned into a die of the tool and the engine block is cast. The lost core material may then be removed to provide the cooling jacket. The engine includes a cylinder block with a cooling jacket circumferentially surrounding first and second siamesed cylinder liners intersecting a closed deck face. The cooling jacket has first and second widths in first and second axial sections, respectively.
