  • Method and system for controlling engine performance
    Patent number: 10343757
    Abstract: Methods and systems are provided for operating a vehicle including an engine comprising a turbocharger including a compressor and a turbine. The engine further includes a bypass path configured to selectively route gas from downstream of the compressor to upstream of the turbine. In one embodiment, the method comprises selectively increasing gas flow to the engine by adjusting gas flow through the bypass path from downstream of the compressor to upstream of the turbine. In this manner, the performance of the engine may be adjusted for various operating conditions.

  • Systems and apparatus for transferring fluid flow
    Patent number: 8959913
    Abstract: Various apparatuses and systems are provided for a turbocharger. In one example, the turbocharger system includes a first turbine having an exhaust flow outlet and a second turbine having an exhaust flow inlet. The turbocharger system further includes a transition conduit fluidically coupling the outlet of the first turbine to the inlet of the second turbine, the transition conduit including an expansion region upstream of a first bend, and a bypass which routes exhaust flow around the first turbine, the bypass having an exhaust flow outlet fluidically coupled to the transition conduit downstream of the expansion region.

  • System, transition conduit, and article of manufacture for delivering a fluid flow
    Patent number: 8888449
    Abstract: Various systems and apparatuses are provided for a flow delivery system for an engine. In one example, a system includes a first turbine providing an exhaust flow and a second turbine having an inlet and being fluidically coupled to the first turbine. The second turbine further includes a plurality of nozzle vanes positioned within the inlet of the turbine. A transition conduit is curved about an axis and coupled to the inlet and to the first turbine. The transition conduit is configured to impart an angular momentum component to at least a portion of the exhaust flow, and includes a slot that delivers at least a portion of the exhaust flow to the plurality of nozzle vanes.
