Abstract: Various systems and methods are provided for controlling operation of a turbocharger compressor. In one example, a system includes a turbocharger including a turbine positioned in an exhaust passage and a compressor positioned in an intake passage, an engine bypass passage having an inlet fluidically coupled to an outlet of the compressor and an outlet fluidically coupled to an inlet of the turbine, an engine bypass valve to control flow through the engine bypass passage, and a controller configured to adjust a position of the engine bypass valve to maintain compressor operation within a designated compressor efficiency region.

Abstract: Various methods and systems are provided for a variable geometry ported shroud for a turbocharger. In one example, a compressor system includes a compressor housing defining an air inlet, a shroud, and a bypass passage, a compressor wheel housed in the compressor housing and surrounded by the shroud, only a single port passing through the shroud and fluidically coupled to the bypass passage, and a ring configured to move axially to adjust a restriction of the port.
