Abstract
An electronic control apparatus for an internal combustion engine having engine sensors, actuators, and a signal processor, contains an improved interface unit for coupling signals to the actuators in response to an output from the processor based upon sensor signals. The interface unit includes a scheme for generating event timing signals in accordance with the prescribed timing signal pattern generated by a stage pulse generator. Depending upon the operational conditions of the engine, the processor supplies a control code through which the timing signals that are produced are altered. This control code is used to alter the rate of occurrence or frequency of generation of the timing signals so that specific actuator control functions may be varied depending upon the engine operation conditions.
