ABSTRACT:
The invention contemplates an electronic control unit in the form of a square-wave generator to serve the function of throttle and enrichment control in a fuel-injected internal-combustion engine. The output of the square-wave generator is an appropriately timed succession of square-wave pulses, of width (in terms of crankshaft rotation) which currently reflects computed evaluation of inlet-air temperature and pressure, engine speed, and start-up running condition of the engine. Under conditions of cold starting the pulse width of the square wave pulses is increased to provide fuel enrichment and, dependent upon engine throttle position the frequency of the square wave pulses may also be increased to provide additional fuel enrichment.
