Definitions

  • a fuel supply system in accordance with the invention includes a throttle valve for controlling the admission of combustion air to an engine and having an angularly movable spindle, a digital encoder for said throttle valve for producing a digital output corresponding to the angular position of the spindle, and a digital electronic fuel control unit responsive to the output of the digital encoder for controlling the rate at which fuel is supplied to the engine in accordance with the output of the digital encoder.
  • the system shown in FIG. 1 includes a digital electronic fuel control device which controls the supply of fuel, pressurised by a pump 11, to injection nozzles 12 in an air intake manifold 13 of the engine.
  • the digital control device 10 has inputs from a speed sensing device 14 and from a digital encoder 15 associated with a throttle 16 which controls admission of combustion air to the manifold 13 under the control of a pedal 17.
  • the timing of the injections is controlled by a timing device 18.
  • the quantity injected in each cycle is controlled by the device 10.
