An engine timing input system (400) is described for pulse detonation engines that allows for accurate engine timing when rotary or cylindrical valves are used to distribute an air/fuel mixture for combustion. The invention uses a profile disk (160) having a predetermined circumferential edge (405) corresponding to valve position to provide for accurate engine timing. A frequency wheel (170) is used in conjunction with the profile disk (160) to provide a more accurate representation of valve position by partitioning the valve position into multiple pulses during each rotation of the rotary or cylindrical valve. The profile disk (160) and frequency wheel (170) when used with programmable timing circuitry signal fuel valve timing and ignition relative to the rotating valve.
