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 only input manual control is a "throttle" displacement, and the output 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 vs. running condition of the engine.
