Abstract

A turbocharger for use with an internal combustion engine is provided. The turbocharger comprises a differential device having a carrier portion, a compressor portion, and a turbine portion. The compressor portion is in driving engagement with a first portion of the differential device. The turbine portion is in driving engagement with a second portion of the differential device. The carrier portion of the differential device is in driving engagement with an infinitely variable transmission. The infinitely variable transmission is in driving engagement with the internal combustion engine. The turbocharger is simply controlled, reduces turbo lag, decreases a boost threshold of the turbocharger, and increases an efficiency of the internal combustion engine.
