ELECTRONIC ENGINE CONTROL APPARATUS Abstract of the Disclosure Signals from a plurality of sensors for detecting operating states of an engine are converted into digital signals, and an actuator is driven by data processed by means of an arithmetic processing circuit on the basis of the digital signals to control the engine. Electronic engine control apparatus comprises a group of reference registers for retaining the arithmetic processing data, a group of instantaneous registers for retaining instantaneous states of the engine, a stage signal generator circuit for generating stage signals which correspond to the respective registers constituting the group of instantaneous registers and which serve to count contents of the corresponding instantaneous registers in a fixed sequence, and a timer register for altering a period of the stage signals. The data from the arithmetic processing circuit is set in the timing registers, the contents of the corresponding instant- aneous registers being counted in periods according to the data, and the actuator is driven on the basis of relations between the count values and the reference registers.
