  • Publication number: 20140013740
    Abstract: An exemplary turbocharger system for an internal combustion engine is provided. The turbocharger system includes a first turbine and a second turbine. The first turbine is in fluid communication with the internal combustion engine. The first turbine receives a first portion exhaust gas discharged from the internal combustion engine and provides a first turbine exhaust gas. The second turbine is in fluid communication with the first turbine via an inter-stage channel. The inter-stage channel transports the first turbine exhaust gas from the first turbine to the second turbine. The inter-stage channel is in thermal connection with an exhaust gas recirculation channel defined between an inlet and an outlet of the internal combustion engine. The first turbine exhaust gas flowing through the inter-stage channel is capable of being heated by a second portion exhaust gas discharged from the internal combustion engine and flowing through the exhaust gas recirculation channel.

  • Publication number: 20120227400
    Abstract: A turbine system for a multistage turbocharger and a method for utilizing the same are disclosed. The turbine system includes a high pressure turbine having an inlet for receiving a flow of fluid, and an outlet for passing the flow on extraction of work from the high pressure turbine. The system further includes a low pressure turbine, having an inlet for receiving a flow of fluid from the high pressure turbine. A diffuser connects the outlet of the high pressure turbine and the inlet of the low pressure turbine. The system also includes a bypass channel for bypassing a portion of the flow around the high pressure turbine, from upstream of the high pressure turbine to downstream of the high pressure turbine. The system includes an injector to input the bypass flow in the diffuser in a manner to reduce flow separation in the diffuser.

  • Patent number: 8206078
    Abstract: A system is provided for monitoring radial motion of a rotating shaft of a turbocharger. The turbocharger includes a compressor and a turbine coupled to opposing ends of the shaft. The system includes a thrust collar including a cylindrical portion and a flange configured to radially extend from one end of the cylindrical portion. The thrust collar is configured to rotate with the shaft. A sensor is positioned within a separation of an outer surface of the thrust collar flange, and the sensor is configured to monitor the separation as indicative of the radial motion of the shaft. Additionally, a method is provided for monitoring radial motion of a rotating shaft of a turbocharger.

  • Patent number: 7101151
    Abstract: A diffuser (30) for a centrifugal compressor (60) having a flow slot (34) formed between the leading edge portion (36) of a diffuser vane (32) and an adjoining diffuser wall (70) for the passage of working fluid (67) over the vane from the pressure side ((40) to the suction side (42) of the vane. The portion (38) of the working fluid passing over the vane is injected into the flow boundary region (43), thereby minimizing the growth of a flow separation zone (58) along the suction side.

  • Patent number: 6994526
    Abstract: Compressor wheel and techniques for manufacturing such a wheel are provided. The wheel may include a hub with a counterbore internally treated to impart residual compressive stresses for enhanced endurance to stress-induced fatigue. The surface treatment allows extending the counterbore relatively closer to a plane of typical maximum stress of the wheel. This design flexibility advantageously allows avoiding or reducing overhang of the compressor wheel, thereby improving rotor dynamics and reducing the axial length of the hub, and the overall foot print of the compressor wheel.
