ABSTRACT:
A pulse generator of the corona discharge type for sensing engine crankshaft angle in an engine control system having a rotor with a plurality of pulse generating elements angularly spaced about the rotor axis. In order to generate as many pulses for each revolution of the rotor as desired to permit accurate measurement of the angular displacement of the rotor axis from a reference point, the rotor is constructed of a disc having a plurality of angularly equally spaced apart segmented regions to act as the pulse generating elements, and at least one electrode is stationarily mounted with respect to the disc to form an air gap to generate corona discharges thereacross in succession in cooperation with each one of the segmented regions upon rotation of the disc. An impedance element is provided to develop a voltage signal in response to the generation of the corona discharge.
