Enhanced Response Turbocharger Using Motor/Generator

Abstract:

A turbocharger system which is used in an internal combustion engine and particularly suitable for use in an on-road vehicle is provided with a turbocharger including a turbine, a compressor and a turboshaft coupling the turbine and the compressor together. A turbo lag is produced in a turbocharger. A solution to this is mechanically coupling it to a motor/generator (motor which acts as a generator when required); storing the power in battery when boost available exceeds the required boost; and rotating the turbocharger shaft using motor during insufficient turbocharger boost. The turbocharger provides a compact and efficient method of storing energy in the battery during excess period of turbocharger boost, and retrieving energy from the battery (using motor) during periods of insufficient turbocharger boost.
