A hydraulic drive assists to increase the acceleration rate of a turbocharger impeller/turbine shaft assembly and provide a secondary means of driving the compressor impeller at lower engine speeds where exhaust gases alone does not generate adequate shaft speeds to create significant induction boost. The hydraulic circuit includes a dual displacement motor, which provides high torque for acceleration yet converts to a single motor for high-speed operation. When the exhaust driven turbine function allows compressor speeds, beyond which the hydraulic syst...
1. A hydraulically driven forced air induction system operative to boost inlet air pressure of a vehicle combustion system, said system comprising: a centrifugal compressor operative to compress combustion system inlet air;a first positive displacement hydraulic motor including an output drive shaft drivingly engaging said centrifugal compressor through a speed increaser mechanism operative to drive said centrifugal compressor at a rotational rate exceeding the rate of said first motor output drive shaft;a second positive displacement hydraulic motor inc...
