AN OPTO-ELECTRONIC TORQUEMETER FOR ENGINE CONTROL

An optical means of measuring torque is described having high accuracy and reliability combined with modest cost. Details of an instrument which was adapted to a transmission output shaft are given. Torque, rpm, and their time rates of change are envisaged as inputs to a microprocessor for the generation of feedback control signals for timing, fuel-air ratio, and fuel.
