Publication number: 20190153930Abstract: A turbocharger includes a turbine wheel configured to impart torque to a drive shaft, a compressor wheel configured to be driven by a driven shaft, a one-way clutch operatively connecting the drive shaft and the driven shaft such that the drive shaft can impart torque to the driven shaft and the driven shaft can overrun the drive shaft, and a motor-generator capable of imparting torque to the driven shaft or the compressor wheel, and/or generating an electric current. The motor-generator generates electric current via torque provided from the drive shaft. An energy storage device can be selectively regenerated by electric current generated by the motor-generator. The motor-generator is configured to alternately regenerate the energy storage device and drive the driven shaft at overrun speeds relative to the drive shaft. The turbine wheel can be driven by internal combustion engine (ICE) exhaust. An ICE may utilize a plurality of such turbochargers.Type: ApplicationFiled: November 21, 2017Publication date: May 23, 2019Inventor: Cesare Maria Meano
