Abstract

PURPOSE: To correct the air-fuel-ratio according to the varying the characteristic of the exhaust sensor by supplying a corrective signal output circuit which outputs a correcting signal according to the maximum or the minimum value of the exhaust sensor output to delay the reise time or the cut-off time.
CONSTITUTION: A corrective signal output circuit 8 puts out a correcting signal u according to the maximum or the minimum value of an output a from an exhaust sensor 3 so that a deviation signal P sent from a deviation detecting circuit 4 may delay to rise or be cut off. A control circuit 5 develops a control signal v according to the correcting signal u, which controls a fuel metering equipment 6.
