ABSTRACT:
A controller for a three wheel turbocharger receives input parameters from throttle or fuel rack position, manifold absolute pressure and accumulator pressure. The operating parameters are used by the controller to control the amount of hydraulic fluid applied to the third turbine wheel of the turbocharger through various operational modes including pump bypass, power transfer, lugging or override, and accumulator charging modes. The controller is designed so that a simple moveable shuttle within a cylindrical housing provides various valve functions interconnecting the various components.
