摘要： In a double air-fuel ratio sensor system having three-way catalysts, a full O.sub.2 storage amount of the three-way catalysts is estimated and compared with a predetermined amount. When the estimated full O.sub.2 storage amount is smaller than the predetermined amount, the three-way catalysts are determined to have deteriorated.

摘要： An idling speed control device normally controlling the idling speed of the engine so that it becomes equal to a desired idling speed. At the time of acceleration, the lean time and the rich time of the air-fuel mixture are calculated during the lean-rich discriminating time, which is basically equal to a time of an occurrence of the lean time and the rich time when the air-fuel ratio is maintained at the stoichiometric air-fuel ratio at the time of acceleration. If the lean time becomes considerably longer than the rich time when the engine is started, the idling speed is increased.

The apparatus also includes a power control unit for comparing the heater resistance value detected by the resistance/power detection unit with a target resistance value and for supplying the heater with power supplied from a battery in a definite-resistance control mode in which the heater resistance value is controlled to become equal to the target resistance value, a resistance value correction unit for correcting the target resistance value so that a difference between the amount of power detected by the resistance/power detection unit and a standard amount of power becomes equal to zero, and a storage unit for storing the target resistance value corrected by the resistance value correction unit as a learning value. Further, the apparatus includes a storage state judgment unit for judging whether or not the the learning value is correctly stored in the storage unit, and a stop unit for stopping the power control unit to supply the heater with power in the definite-resistance control mode.

摘要： A fuel injection control device in which the amount of fuel injected by the fuel injector is increased at the time of acceleration. Namely, at the time of acceleration, the lean time and the rich time of the air-fuel mixture are calculated during the lean-rich discriminating time, which is basically equal to a time of an occurence of the lean time and the rich time when the air-fuel ratio is maintained at the stoichiometric air-fuel ratio at the time of acceleration. When the lean time becomes considerably longer than the rich time, the amount of fuel injected by the fuel injector is further increased.

摘要： A fuel injection control device in which it is determined whether the air-fuel mixture is lean or rich at a predetermined crankangle during a lean-rich discriminating time at the time of acceleration. The lean-rich discriminating time is shortened as the degree of the acceleration becomes larger, and the times of being lean and the times of being rich within the lean-rich discriminating time are calculated. When the times of being lean are larger than the times of being rich, and the difference therebetween is larger than a predetermined value, the accelerating increasing rate of the amount of fuel fed into the engine cylinder is increased.

摘要： In an internal combustion engine, a heater for heating an air-fuel ratio sensor provided in the exhaust gas flow passage is controlled in accordance with a parameter of a load of the engine. That is, the heater is turned ON when the load parameter is not larger than a predetermined value, and the heater is turned OFF when the load parameter is larger than the predetermined value. The turning OFF of the heater is delayed with a predetermined delay time when the engine rotational speed is lower than a predetermined value, and the turning ON of the heater is delayed with the predetermined delay time when the engine rotational speed is higher than the predetermined value. Thus, the number of times that the heater is turned ON and OFF is decreased, thereby prolonging the life of the heater.
