  • Patent number: 11965470
    Abstract: In accordance with one aspect of the present disclosure, a turbocharger includes a compressor having a compressor wheel, a turbine provided within a housing, and an exhaust gas recirculation (EGR) flow path. The EGR flow path includes a first fluid connection in the housing and located in proximity to the turbine, a second fluid connection located in proximity to a trailing edge of the compressor wheel, an EGR control valve disposed between the first fluid connection and the second fluid connection, the EGR control valve configured to selectively operate the turbocharger in a low-heat mode having an EGR up to 50% and an operational mode having an EGR rate typically less than 35%.

  • Publication number: 20230349385
    Abstract: A rotating machine for delivering a working fluid to a system includes a compressor housing defining a compressor housing interior and partially defining a flow path. The rotating machine also includes a shaft and a compressor wheel disposed in the compressor housing interior. The rotating machine additionally includes a backplate coupled to the compressor housing and further defining the flow path. The backplate and the compressor housing are configured to direct working fluid from the compressor housing interior through the flow path. The backplate defines a working fluid connection adjacent the compressor wheel and/or the flow path such that the working fluid connection is fluidly coupled to the flow path and such that the compressor wheel delivers working fluid from the compressor housing interior and the working fluid connection to the flow path.

  • Patent number: 10947931
    Abstract: A product may include a bearing housing in which a shaft may be supported by a bearing so that it may rotate. A compressor wheel may be disposed on the shaft. A compressor cover may be connected with the bearing housing, which may form a compressor body and may define a chamber within which the compressor wheel may rotate. A diffuser may extend radially outward from the chamber and may receive gas from the compressor wheel. An inlet may be provided to the compressor body, which may receive a supply of exhaust gas. An EGR distribution cavity may be defined within the compressor body and may extend around the shaft. An EGR inlet channel may extend into the bearing housing from the inlet to the EGR distribution cavity. An EGR passage may extend from the EGR distribution cavity to the diffuser.
