In an electronic engine control apparatus in which ignition timing and fuel injection quantity are calculated from the negative pressure in an intake manifold of the engine or from a flow rate of suction air and the rotational speed of the engine, a reference register group is constituted of register for storing the result of the calculation while an instantaneous register group is made up of registers for storing the instantaneous states of actuators. One of the registers of the instantaneous register group is selected according to a stage timing signal, so that the contents of the two registers selected are compared with each other for producing control pulses for driving actuators such as an ignition coil or fuel injector. The reference register group contains a register desigated a CYL register and the instantaneous register group contains a register designated a CYL counter for dividing reference pulses from an angular position sensor in accordance with the number of engine cylinders, so that the engine control apparatus may be employed in various engines of different cylinder numbers such as a 4, 6, 8 or 12 cylinder engine. |
