METHODS AND SYSTEMS FOR BOOST CONTROL
Abstract:
Methods and systems are provided for managing a compressor temperature using EGR to address surge and condensation. A variable mixture of cooled compressor recirculation flow and hot EGR is provided to a compressor inlet. A composition of the mixture is adjusted to maintain a compressor inlet temperature sufficiently warm so as to reduce ingestion of condensation, and a compressor outlet temperature sufficiently cold to be within component temperature limits with flow above the surge limit.
