Abstract
A control apparatus for controlling the fuel metering device of an internal combustion engine uses a computer and servomotor to override the accelerator when the engine reaches a predetermined threshold speed for a selected throttle valve position. Preset values stored in the computer assure favorable fuel consumption during acceleration above the threshold speed.
Claims8
A control apparatus for providing favorable fuel consumption during operation of an internal combustion engine in response to operation of an accelerator pedal, said engine having a controllable fuel metering device, comprising:
- servomotor means for actuating said fuel metering device;
- first means for providing an output indicative of the position of said accelerator pedal;
- second means for generating signals indicative of engine rotational speed;
- and
- means responsive to said pedal position and said engine speed signals for controlling the setting of said fuel metering device, said setting of said fuel metering device being dependent only on said pedal position in a first range of values for said speed signals, and said setting being dependent only on said speed signals in a second range of values for said speed signals, said second range higher than said first range.

- servomotor means for actuating said fuel metering device;
- first means for generating signals indicative of the position of said accelerator pedal;
- second means for generating signals indicative of engine rotational speed;
- and
- means responsive to said pedal position signals and said engine speed signals for generating an output signal to actuate said servomotor means, said output signal having a value dependent only on said pedal position signals in a first range of values for said speed signals, and said output signals having a value dependent only on said speed signals in a second range of values for said speed signals, said second range higher than said first range.
