Abstract: Methods and systems are provided for a noise mitigating device for a turbocharger compressor. In one example, the noise mitigating device includes a set of perforated rings arranged in a recirculation passage of a compressor casing treatment. The rings of the set of perforated rings may be oriented so that apertures of one ring are offset from apertures of one or more adjacent rings, forcing air to flow through the apertures via a non-linear path while deflecting at least a portion of sounds waves generated in the compressor.

Abstract: Methods and systems are provided for a compressor having a variable inlet device and an active casing treatment. In one arrangement, a system for a compressor may include a casing forming a recirculation passage surrounding an inlet passage, an active casing treatment surrounding the inlet passage and configured to selectively control gas flow through the recirculation passage, an impeller, and a variable inlet device positioned in the inlet passage upstream of the impeller and configured to selectively reduce an effective size of the impeller. The variable inlet device and the active casing treatment may be adjusted based on operating conditions in order to increase a flow range of the compressor while providing high compressor efficiency.

Abstract: Methods and systems are provided for compound boosted engine comprising an electric supercharger. In one example, the electric supercharger may be double-ended with a compressor arranged on either side of an electric motor and rotationally coupled to the electric motor via shafts. The electric supercharger may be configured to provide boost assist to a twin turbocharger system via a bypass channel adapted with a bypass valve.

Abstract: Methods and systems are provided for merging recirculated exhaust gas (EGR) with fresh intake air in an intake passage. In one example, a method may include introducing EGR to the intake passage via an angled annular slot and flowing unmixed EGR and ambient air through an intake compressor inlet. Ambient air may flow to a center of the intake compressor while the EGR may flow along a periphery of the intake compressor inlet.

Abstract: An exhaust gas recirculation system for an engine includes a conduit, and a mixer. The conduit is configured to direct to direct exhaust gas away from an exhaust manifold. The mixer is configured to direct exhaust gas from the conduit, into an engine air intake system. The mixer is arranged with an exhaust gas mixing volute chamber having a plurality of mixing vanes configured to direct the exhaust gas into a central intake airflow upstream of an intake manifold.

Abstract: An exhaust gas recirculation system for an engine includes a conduit, and a U-shaped exhaust gas mixer. The conduit is configured to direct an exhaust gas away from an exhaust manifold. The U-shaped exhaust gas mixer is configured to direct exhaust gas from the conduit and into an engine air intake system. The U-shaped exhaust gas mixer is arranged with a pre-mixing cavity configured to disperse the exhaust gas and entraining the exhaust gas into an intake air flow prior to distribution into an intake manifold of an engine.
