    摘要： A turbocharger includes a turbine section, a compressor section and a bearing section. A turbine wheel and a compressor wheel are mounted on a shaft and the shaft is rotatably mounted in a bore of a housing. A lubrication system circulates lubricant through the bearing section. First and second spaced apart seals are positioned along the shaft. A recess is positioned between the first seal and the second seal to define an air buffer chamber. The air buffer chamber is provided with pressurized air to discourage lubricant leakage past the first seal.

    摘要： A frictional welding process for joining a titanium aluminide turbine to a titanium alloy shaft is disclosed. The disclosed process includes preheating the turbine to a designated temperature, providing a specially-designed joining interface geometry at the distal end of the shaft and optimizing the frictional welding parameters. The frictional welding is carried out in multiple steps but, while the shaft is being spun by a rotating chuck, two different pressures and two different time periods are used until the narrower portions of the distal end of the shaft have been fused onto the welding surface of the turbine. Then, an additional forging step with yet another engagement pressure between the shaft and the turbine is carried out without rotation of the shaft.

    摘要： An internal combustion engine system includes an engine having an engine housing. The engine system further includes an exhaust system, and a turbine disposed within the exhaust system. A particulate reduction device is disposed in the exhaust system upstream of the turbine. The particulate reduction device includes an exhaust retarder having a flow property which is based at least in part on a residence requirement for combustion of particulates in exhaust gases passing therethrough. The flow property may be a flow restriction property, and the exhaust retarder may include a flow restricting trapping element configured to trap particulates in the exhaust gases. The flow restricting trapping element defines a combustion efficacy to exhaust mass flow and temperature coefficient for the particulate reduction device which is based at least in part on a combustion initiating residence requirement for particulates passing through the particulate reduction device.

    摘要： A valve seat insert operable with a valve to selectively open and close a passage to a cylinder in an internal combustion engine. The valve seat insert includes a cobalt alloy base including at least about 40 wt % Co and at least about 5 wt % Cr. An oxide scale coating is disposed on at least a wear face of the valve seat insert adapted to engage the valve and optionally on a portion of the valve.
