摘要： A fluid motor is disclosed employed in a turbocharger to spin-up the turbocharger turbine independently of the existing exhaust gas pressure on the exhaust turbine wheel. A fluid turbine wheel is fixedly attached to the rotary mounted shaft of the turbocharger. Fixedly mounted nozzles directed at the fluid turbine wheel present fluid from a controlled source of pressurized fluid. A fixedly mounted collector receiving exhausted fluid from the fluid turbine wheel. The fluid is recycled from the collector to the controlled source of pressurized fluid and then back to the fixedly mounted. The fluid turbine wheel exhausts the fluid with residual energy to the collector. The controlled source of pressurized fluid includes a gear pump with an accumulator and a solenoid valve.
