A hybrid hydraulic turbocharger system for internal combustion engines. The turbocharger system includes a hydraulic pump motor in mechanical communication with said engine drive shaft. A hybrid turbocharger unit includes an engine exhaust gas turbine driving a compressor, a hydraulic turbine and a hydraulic pump, all mounted on said turbocharger shaft. The hydraulic pump motor functions as a hydraulic pump driven by the drive shaft of the engine to provide additional boost to the turbocharger unit at low engine speeds and functions as a hydraulic motor driven by the turbocharger pump to provide additional torque to the engine drive shaft high engine speeds. Additionally, this system provides for brake energy recovery by storing the energy absorbed during the breaking cycle and releasing it back to the pump motor when required during the subsequent acceleration cycle.
