ABSTRACT:
An example system for inducting air into an engine includes a compressor and a turbine mechanically coupled to the compressor and driven by expanding engine exhaust. The system also includes high pressure (HP) and low pressure (LP) exhaust gas recirculation (EGR). The disclosed system allows EGR to be routed from an HP take-off point to an LP mixing point. Such functionality may be useful in averting compressor surge and increasing EGR flow potential under certain operating conditions.
