ABSTRACT:
A method and apparatus for controlling the various functions of an internal combustion engine using a program-controlled microprocessor having a memory preprogrammed with various control laws and associated control schedules receives information concerning one or more engine-operating parameters such as manifold pressure, throttle position, engine coolant temperature, air temperature, and engine speed or period and the like. These parameters are sensed or measured and then the value thereof is supplied to input circuits for signal conditioning and conversion to digital words usable by the microprocessor. The microprocessor system computes digital control words indicative of particular computer-commanded engine control operations and output circuitry responds to predetermined computer-generated commands and to the computed digital command words for converting them into corresponding pulse-width control signals for controlling such engine operations as fuel-injection, ignition timing, proportional and/or on-off EGR control, and the like. The engine control system further includes an oxygen sensor feedback system for providing reliable data to said microprocessor for command control purposes. In particular the oxygen sensor signal is sampled a predetermined number of times per each engine revolution and the totality of each sampling is determined per revolution. This generates a digital word representing the condition of the air/fuel ratio of the engine over each revolution.
