Prime mover fuel efficiency control system

摘要

A system for determining and controlling the power being transmitted through a rotated shaft from a fuel-consuming engine, which includes a husk assembly associated with the shaft and providing electrical signals proportional to shaft torque, a tachometer for providing electrical signals proportional to shaft rotational speed, electrical circuitry for electronically multiplying the torque signals by the RPM signals to determine shaft horsepower, a dividing network for dividing the shaft horsepower signal into an electrical signal representing the rate of fuel consumption to provide a continuous indication of instantaneous system efficiency, a first control network connected to receive the shaft RPM signals for providing both variable and on-off feedback signals for controlling the speed of the engine and a second control network connected to receive the shaft torque signals for providing both variable and on-off torque control signals for feedback control of the engine to enable the direct supervision of engine operating parameters and automatic control so as to increase fuel efficiency.
