  • TURBOCHARGER WITH TWO-STAGE SERIES COMPRESSOR DRIVEN BY EXHAUST GAS-DRIVEN TURBINE AND ELECTRIC MOTOR
    Publication number: 20170335756
    Abstract: A turbocharger includes a two-stage serial compressor having a first impeller and a second impeller affixed to a shaft and arranged in series for a two-stage compression of air, an exhaust gas-driven turbine having a turbine wheel affixed to the shaft, and an electric motor mounted on the shaft for assisting the turbine in rotatably driving the compressor.

  • Compressed-air-assisted turbocharger system for internal combustion engine
    Patent number: 8434305
    Abstract: A turbocharger system for an internal combustion engine that powers a vehicle having a pressure vessel storing pressurized air. The turbocharger system comprises a turbocharger and a valve system. The system is configured such that the air intake system of the internal combustion engine can be supplied with air at super-atmospheric pressure either from the compressor of the turbocharger or from the pressure vessel. When the pressure vessel is supplying the intake system, compressed air from the compressor is recirculated back to the air inlet of the compressor so as to help prevent a surge condition in the compressor.
