Abstract
An improved hydraulic assist turbocharger system is provided for supplying charge air to a combustion engine. The system includes at least one turbocharger having an hydraulic assist turbine adapted to be driven by a pressurized hydraulic fluid to supplementally drive the turbocharger during selected engine operating conditions when supplemental charge air flow is required. Hydraulic fluid flow is regulated by an electrohydraulic control valve responsive to control signals from a main controller, wherein the control signals and corresponding control valve operation may be independent of engine speed and load. In addition, the hydraulic fluid is supplied to the hydraulic assist turbine via a dual segment nozzle, with appropriate selector valves coupling the fluid for passage through one or both nozzle segments in accordance with engine charge air requirements. The entire system, inclusive of the turbocharger and related control components, is conveniently provided as a unitary package adapted for facilitated mounting onto a combustion engine.
