ABSTRACT:
A torque converter output augmentation apparatus includes a torque converter connected between an engine and a driven component in a drive train. The torque converter is connected into a hydraulic circuit along with a hydraulic fluid pressurizer, a hydraulic fluid container, and a valve. The hydraulic fluid pressurizer pressurizes hydraulic fluid received from the torque converter and the hydraulic fluid container stores pressurized hydraulic fluid received from the hydraulic fluid pressurizer. A controller is programmed to cause the valve to alternately admit and block pressurized hydraulic fluid flow from the hydraulic fluid container to the torque converter. Pressurized fluid received from the hydraulic fluid container is directed within the torque converter in a manner that augments torque converter output to the driven component.
