ABSTRACT:
A controller for a three-wheel turbocharger is shown for receiving input parameters including: throttle or rack position, manifold absolute pressure, airflow (either mass or volume), and engine RPM. The controller may also use an accumulator. The operating parameters are used by the controller to control the amount of hydraulic fluid applied to the third hydraulic 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 power transfer may be overridden when engine load sensed by manifold absolute pressure or airflow or throttle position is reduced.
