A diesel engine timing apparatus comprising a luminosity probe including a photocell which in response to light generated by combustion of fuel in a selected chamber of the diesel engine generates an on or off signal depending on the respective presence or absence of light. Electronic circuitry elements process the on or off signal to produce an amplified output signal which is transmitted to light-generating elements disposed externally of the engine, e.g., a conventional inductive pick-up, strobe-type timing light. A pulsed visible light signal is thereby generated which may be employed to adjust the engine timing to a selected value in a conventional manner, by aligning of fixed and adjustable timing marks on stationary and motive portions of the diesel engine. The disclosed system is devoid of any magnetic probe or magnetic sensing structure.
