ABSTRACT:
A torque control system for an engine performance test machine for internal combustion engines comprises an oscillating type electric dynamometer including a rotor and an oscillating member being oscillatably supported around said rotor and a connecting device for interconnecting the rotor shaft and the rotating member of the engine. The torque control system also includes a load cell for monitoring oscillating torque of the oscillating member, means for generating a first torque occurring at the rotor, means for generating a second torque occurring at the rotating member. The torque control system also includes means for generating a detection signal representative of the sum of said oscillating torque, and the first and second torques, and a controller for adjusting the torque generated by the engine in response to the detection signal.
