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.

Various methods and systems are provided for adjusting flow resistances in an engine cooling system. In one example, a method for an engine includes adjusting a first resistance of a radiator main return line to be greater than a second resistance of a sub-cooled return line in response to an engine speed below a threshold speed, the sub-cooled return line arranged in parallel with the radiator main return line in an engine cooling system.
