Abstract

PURPOSE: To inexpensively provide for a number of control functions by providing a reference register group, a momentary register group and a comparison result register group such that registers in said respective register groups are connected to a comparator circuit under the control of a stage counter.
CONSTITUTION: The control unit receives detection signals from a air flow meter 14, a water temperature sensor 96, an intake temperature sensor 16, an exhaust temperature sensor 84, a throttle valve position detector 24, an EGR unit 28 and a λ sensor 80 and provides control signals to a fuel injection valve 66, an ignition coil 40, an EGR unit 28 and an air regulator 132. The detection signals are supplied through filters 132 to 144 to a multiplexer 122 in an input output circuit 12. The input output circuit 120 is provided with a pulse output circuit 126, which serves to hold a signal processed by CPU114, and is provided with a reference register group, a momentary register group, comparators and so forth
