ABSTRACT:
A device for measuring the power output of an internal-combustion engine comprises a serial arrangement including a pickup for taking up the speed of rotation of the shaft of the internal-combustion engine, a pulse former, a selector for selecting the speed of rotation of the shaft of the internal-combustion engine, a unit for controlling the device, a unit for producing a train of electric pulses, a unit for determining the difference of two adjacent pulse trains, and a unit for recording the measurement results. Connected to the engine shaft speed selector are an engine duty control unit and a clock pulse generator. The pulse train producing unit is connected to the pulse former to which a unit for producing a preset number of pulses is connected. The device control unit and the unit for producing a preset number of pulses are connected to the unit for determining the difference of two adjacent pulse trains and to the clock pulse generator.
