MOTOR-GENERATOR ASSISTED TURBOCHARGING SYSTEMS FOR USE WITH INTERNAL COMBUSTION ENGINES AND CONTROL SYSTEMS THEREFOR

摘要

A turbocharger system for use with an internal combustion engine includes an assisting motor-generator and control for enhancing turbocharged internal combustion engine performance with reduced losses inherent to turbochargers incorporating waste gates. The controlled assisting motor-generator provides enhanced turbocharger boost with reduced turbo lag below a boost pressure limit, and can generate electric current at high exhaust gas flow rates.
