ABSTRACT:
A device for generating a series of output signals in relation to a rotating output shaft of a diesel fuel test engine generating a series of engine signals, each engine signal occurring at a first angular orientation of the output shaft. Each output signal is generated at a second angular orientation of the output shaft. The device receives the series of engine signals, measures the angle of rotation of the output shaft relative to the occurrence of each engine signal, determines an angular interval between the first and second angular orientations of the output shaft, in the direction of rotation of the output shaft, and generates the output signal when the measured angle of rotation of the output shaft corresponds to the angular interval.
