Definitions

  • ABSTRACT A controlling device for controlling an operation of fuel injection system of an internal combustion engine, comprising an optical means having light absorbing characteristics and a photodetecting means arranged to move relative to said optical means, the optical means has prerecorded optical variation of the light absorbing characteristics corresponding to requested two-dimensional characteristics 01 the operation of the internal combustion engine, the optical variation is detected by the photodetecting means to produce an electric output voltage to control the injection period of fuel injector to obtain desired output characteristics of the internal combustion engine.
  • FIG. 1 shows working characteristics curves of an internal combustion engine expressed by the relation between the duration of fuel injection and engine speed while making load conditions as the parameter;
