  • Patent number: 10508595
    Abstract: An energy recovery system for an engine system is disclosed. The engine system includes an engine, an exhaust conduit configured to receive exhaust gases discharged from the engine, and a first turbocharger coupled to the exhaust conduit to receive exhaust gases from the engine and provides compressed air to the engine. The energy recovery system includes a bypass conduit, a second turbocharger, and an accumulator. The bypass conduit is coupled to the exhaust conduit upstream of the first turbocharger, and facilitates a portion of exhaust gases from the exhaust conduit to bypass the first turbocharger. The second turbocharger is coupled to the bypass conduit, and is driven by the portion of exhaust gases bypassing the first turbocharger to compress air received from an ambient to a first pressure. The accumulator is in fluid communication with the second turbocharger, and stores air received from the second turbocharger at the first pressure.

  • Publication number: 20190106130
    Abstract: An energy recovery system for a power system is disclosed. The power system includes an engine, a generator driven by the engine, an electrical bus configured to receive electrical power from the generator, an exhaust conduit configured to receive exhaust gases from the engine, and a turbocharger coupled to the exhaust conduit. The energy recovery system includes a bypass conduit, a turbo-generator, and a synchronizer. The bypass conduit is coupled to the exhaust conduit, and facilitates a portion of exhaust gases from the exhaust conduit to bypass the turbocharger. The turbo-generator is coupled to the bypass conduit, and is driven by the portion of exhaust gases bypassing the turbocharger. Further, the synchronizer modulates one or more parameters of electrical power received from the turbo-generator based on one or more parameters of electrical power present on the electrical bus. The synchronizer transmits modulated electrical power to the electrical bus.

  • Patent number: 9181855
    Abstract: A turbocharger is disclosed for use with an engine. The turbocharger may include a housing at least partially defining a compressor shroud and a turbine shroud. The turbine shroud may form a volute having an inlet configured to receive exhaust from an exhaust manifold of the engine in a tangential direction. The volute may also include an axial channel disposed downstream of the inlet. The turbocharger may also include a turbine wheel disposed within the turbine shroud that may be configured to receive exhaust from the axial channel. The turbocharger may also include a compressor wheel disposed within the compressor shroud, and a shaft connecting the turbine wheel to the compressor wheel. The turbocharger may also include a nozzle ring disposed within the axial channel at a location upstream of the turbine wheel.
