Abstract: A link assembly for a track comprises a first side plate, and a second side plate coupled with the first side plate such that proximal surfaces of the first and second side plates are disposed in abutment with one another. The link assembly further includes a wear plate assembly that is coupled to a top face of the first side plate and a top face of the second side plate. The wear plate assembly is formed from a material having a wear resistance greater than a wear resistance of the first and second side plates.

Abstract: A method of pressure casting a turbocharger component for an internal combustion engine may include heating an aluminum-scandium alloy to form a molten casting material including up to about 5 wt % scandium that is fully dissolved in the molten casting material, and introducing the molten casting material into a cavity of a mold from a bottom of the mold toward a top of the mold while applying a pressure to the molten casting material with a movable portion of a ram positioned in contact with the bottom of the mold. The method may also include solidifying the molten casting material by cooling the casting material as it comes into contact with a cooling member positioned on the top of the mold, wherein a coolant is pumped through coolant passages formed in the cooling member in order to cool the casting material at a cooling rate such that the solidifying preserves at least 70% of an original amount of the scandium in the aluminum-scandium alloy in solid solution in the casting material.

Abstract: A method of manufacturing a turbocharger component for an internal combustion engine is disclosed. The method may include introducing a material into a mold, wherein the material includes at least one added alloying element. The method may further include applying a pressure to the material, and solidifying the material by cooling the material at a cooling rate, wherein the solidifying preserves an amount of the at least one added alloying element in solid solution in the material. The method may also include forming precipitates within the material by aging the material at an aging temperature.

Abstract: Various examples of system and methods for particulate filters include a particulate filter comprising a housing having a flow axis between an input header and an output header, and a plurality of filter segments arranged in a stacked array, the stacked array disposed within the housing and lying in a plane normal to the flow axis, the stacked array including a first filter segment having a first average flow characteristic per unit area and a second filter segment having a second average flow characteristic per unit area, the first average flow characteristic per unit area different from the second average flow characteristic per unit area, each particular filter segment of the plurality of filter segments having a segment flow axis substantially in parallel alignment with the flow axis.

Abstract: An integral engine component is disclosed. The integral engine component may have a solid first member and a second member cast in place relative to the solid first member. A metallurgical bond may exist between the solid first member and the second member, and the melting temperature of the solid first member may be lower than the melting temperature of the second member.
