An exhaust gas oxygen sensor (23) gives an output signal representative of the air-fuel ratio (A.F.R.) supplied to an engine. Thus signal is compared, by a comparator (27) with a desired value of A.F.R. for the instantaneous values of engine speed and throttle opening from a memory (29). If an error is detected, a correction to the value of throttle angle is determined from a memory (32) and applied to modify the 'on' time of fuel injectors (16) of the engine. |
