Abstract: In one aspect of the present disclosure, a compressor wheel is disclosed that includes a body, a plurality of blades, and one or more supports. The supports add strength to the compressor wheel and may be configured as ribs, for example. The body has a first face (e.g., an outer or front face), which may include the blades, and a second face (e.g. an inner or rear face), which may include the supports. The supports may include an arcuate configuration curving forward in a direction of rotation of the compressor wheel.

Abstract: An engine system (40) includes an engine (42), and a turbocharger (1) that receives exhaust gas from the engine (42) and delivers charged air to the engine (42). The engine system (40) also includes an electrically-driven compressor-expander (60) disposed in the engine air intake passage (48) between a compressor section (10) of the turbocharger (1) and the engine (42). The compressor-expander (60) is configured to modify the pressure and temperature characteristics of the charged air flow exiting the turbocharger compressor section (10). A valve (50) controls the flow path and/or direction of the charged air flow as it enters the compressor-expander (60).
