摘要： An automotive engine control system is provided for an automobile having a variable rotation speed engine which has a plurality of spark plugs served by respective spark plugs. The system includes an optical rotary encoder having a rotatable pulse scale having a row of code pattern with specific light-permeable or light-deflection slits each for outputting a reference position signal and other light-permeable or light-reflection slits each adapted to reduce the amount of light for outputting an angular signal, both of the optical signals being photoelectronically converted and the waveform of the resultant electric signals being shaped based on threshold voltages into electric pulse signals indicative of a reference angle of 0.degree. and the accumulated angle of rotation, in which the circumferential width of each specific reference slit is made narrower than that of other slit so that the pulse width for angular position-indicating of the angular pulse signal is always equal and constant for ensuring more accurate detection of the angle of rotation. As the engine rotation speed is sensed to speed up and slow down, by a sensor that is operatively connected with the engine, the optical rotary encoder varies igniting of the spark plugs.

摘要： An optical encoder comprising a photointerruptor having light-emitting and light-receiving optical fibers and a rotatable pulse scale disposed in an optical path between both of the opposed end faces of the optical fibers so as to shut the optical path intermittently, thereby generating optical pulses in accordance with an angle of rotation of the pulse scale, in which the light-receiving optical fiber has a larger diameter and a greater numerical aperture NA than those of the light-emitting fiber. The light-emitting optical fiber may be replaced with a light-emitting device. Further, a reflector may be interposed in the optical path. Optical pulse signals indicative of an angle of rotation can be detected effectively and it is possible to facilitate the assembling or wiring operation and reduce the production cost.
