ABSTRACT:
The apparatus comprises a luminosity probe to provide an electrical signal in response to the combustion event in a diesel engine and also comprises a probe to provide another electrical signal indicative of top dead center. Both electrical signals are processed and applied to a circuit which generates an output pulse having a duration corresponding to the time between the start of the electrical signals. A meter displays the angle represented by the duration of such pulse. Circuitry is provided to compensate for offset.
