Abstract:
Methods and systems are provided for an engine system configured with a wide range active compressor and high pressure EGR. In one example, a compressor may include an active casing treatment with a slideable sleeve may be adjusted to direct air flow through either a choke slot and surge slot to control compressor efficiency, thereby maintaining EGR flow. In another example, the compressor may comprise a variable inlet device to regulate air flow through the compressor, thereby adjusting compressor efficiency and also maintaining EGR flow.

Claim (Index 13):
A method, comprising:\n responsive to operation of a wide range active compressor (WRAC) within a surge region, adjusting the WRAC to a first position to alleviate compressor surge; responsive to engine operation at an engine pressure differential less than a threshold, and operation of the WRAC outside of the surge region, adjusting the WRAC to a second position to decrease compressor efficiency and increase the engine pressure differential to flow EGR; and responsive to the engine pressure differential rising above the threshold, adjusting the WRAC to the first position to increase compressor efficiency during WRAC operation outside of the surge region.
