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. The microprocessor-based control system receives information concerning one or more engine-operating parameters such as manifold absolute pressure, throttle position, engine coolant temperature, air temperature, and engine speed or period and the like. These parameters are sensed or measured and the analog sensor output signals are supplied to input circuits for signal conditioning and conversion into digital words usable by the microprocessor system. The microprocessor system computes a digital word commanding a particular computer-commanded engine control operation and output circuitry responds to particular computer-generated commands and to the computed digital command words for converting them to corresponding pulse-width control signals for controlling such engine operations as fuel-injection ignition timing, proportional and/or on-off EGR control, or the like.
