摘要： An air/fuel ratio feedback control method which is adapted to control the air/fuel ratio of an air/fuel mixture being supplied to an internal combustion engine in response to the output of a means for detecting the concentration of an ingredient in the exhaust gases emitted from the engine. When the engine is operating in a predetermined feedback control region, control of the air/fuel ratio of the air/fuel mixture is carried out by the use of a first coefficient which has a value variable in response to the output of the aforementioned ingredient concentration detecting means, and simultaneously, the value of a second coefficient, which is a mean value of values of the first coefficient, is determined. When there occurs a transition in the operating condition of the engine from the feedback control region to one of a plurality of particular operating regions, the value of the first coefficient is held at a value of the same coefficient, obtained immediately before the above transition, and the held value is applied for the air/fuel ratio control until a predetermined period of time elapses, after the transition. After the above predetermined period of time elapses, the air/fuel ratio is controlled by the use of the aforementioned second coefficient in place of the above first coefficient. When the operation of the engine is returned to the feedback control region before the aforementioned predetermined period of time elapses, the above held value of the first coefficient is initially used as an initial value to control the air/fuel ratio. Preferably, the above predetermined period of time is set to a period of time required for completing a speed changing operation of the transmission gear of the engine. The aforementioned particular operating regions include a mixture-leaning region, a decelerating region and a fuel-cut effecting region.

摘要： An air/fuel ratio feedback control system for internal combustion engines, which is arranged such that when a pulse motor for driving an air/fuel ratio control valve passes the switching point of position detecting means during feedback control operation, a value indicative of the number of steps corresponding to the reference position of the pulse motor, stored in a memory in an electrical circuit for driving the pulse motor is simultaneously shifted to an actual position counter. Air/fuel ratio control can be achieved with accuracy on the basis of a count in the above actual position counter which thus exactly corresponds to the actual position of the pulse motor.
