Abstract
After starting of an internal combustion engine, a quantity of fuel to be supplied to the engine is increased by the use of a fuel increment, and at the same time a period of time is counted which elapses from the time an oxygen concentration sensor has its internal resistance decreased below a predetermined value. When the period of time counted exceeds a predetermined period of time, the increase of the quantity of fuel is terminated and simultaneously calculation of a correction value responsive to oxygen concentration in exhaust gases sensed by the sensor is started, and the quantity of fuel is corrected by means of the correction value calculated. A temperature in the engine intake system is sensed, and the above predetermined period of time is to a larger value as the sensed intake system temperature is higher.
