ABSTRACT:
A device for correcting the air/fuel ratio of a mixture being supplied to an internal combustion engine, by the use of a correction coefficient which has its value determined as a function of intake air temperature in the intake pipe of the engine. The correction coefficient has a predetermined constant value at intake air temperature higher than a predetermined value, and has its value increasing as the intake air temperature decreases from the above predetermined value. A decrease in the evaporation rate of fuel being supplied to the engine at low intake air temperature is thus compensated for by the above air/fuel ratio correction.
