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 relating to one or more actual engine operating parameters such as manifold absolute pressure, throttle position, engine coolant temperature, air temperature, engine speed or period or the like. These parameters are sensed and then supplied to input circuits for signal conditioning and conversion to digital words usable by the microprocessor. The microprocessor system computes one or more digital 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 generating 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. A fuel management control "limp home" circuit is also disclosed which will allow a vehicle to be driven for a short distance such as to a repair station or the like whenever the microprocessor-controlled fuel injection system fails to function properly.
