Abstract

The present invention is a hydraulically-assisted turbocharger system (10) having a selectively engagable pump (20), a camshaft (54) having at least one cam (56), with the cam (56) operably associated with the pump (20), a turbocharger unit (12) having a compressor (18) and a turbine (14), and a hydraulically actuated driver (16) for driving the turbocharger (12), the driver being in fluid communication with the pump (20), connected to the turbocharger and the pump (20). When the cam (56) rotates, and the pump (20) is activated, the cam (56) will cause the pump (20) to deliver pressurized fluid through the hydraulically actuated driver (16) for driving the turbocharger (12), thereby causing the compressor (18) to compress air, and when the pump (20) is deactivated, no fluid is pumped for driving the turbocharger (12).
