Abstract:
Methods and systems are provided for a compressor of a turbocharger of an engine. In one example, a compressor may include a flow passage and a resonance chamber surrounding the flow passage, with the flow passage fluidly coupled with the resonance chamber by a recirculation passage, a bleed passage, and a plurality of apertures positioned between the recirculation passage and the bleed passage. Flowing fluid from the resonance chamber, through the apertures, and into the flow passage may reduce a noise level of the compressor.
