    Abstract: The invention relates to a method for compensating for incorrect adaptations of the precontrol of the fuel metering of an internal combustion engine that is operated in at least two operating modes, namely homogeneous normal operation and stratified charge operation. The inventive method is further characterized in that mixture control and adaptation of said mixture control takes place in the homogeneous normal operation. Depending on a desired operation, the control switches between the two operating modes, said desired operation being determined by a plurality of operating mode requirements, a priority being allocated to every operating mode requirement. The desired operation is determined depending on the priorities of the operating mode requirements. The physical urgency of the adaptation is increased by different intervals, thereby requiring a switch to the homogeneous operation.

    Abstract: An air-fuel ratio control apparatus (34) adapted for an internal combustion engine (2) equipped with a purge system (30). The air-fuel ratio control apparatus estimates the amount of fuel vapor present in a fuel tank (18) from a balance between an estimated produced vapor amount and an estimated purged amount of fuel vapor. When the estimated amount of fuel vapor present is small, the concentration of fuel vapor to be purged is low, so that a base air-fuel ratio feedback coefficient is learned in a period where the estimated value is small. As a result, the base air-fuel ratio feedback coefficient is appropriate learned. Even if the base air-fuel ratio feedback coefficient is learned incorrectly, the air-fuel ratio control apparatus can correct the feedback coefficient. Accordingly, the concentration of the fuel vapor to be purged into the intake air can be detected accurately, thus permitting the base air-fuel ratio feedback coefficient to be maintained at a more appropriate value.

    Abstract: In an apparatus in which a fuel injection quantity Ti is computed by correcting a basic fuel injection quantity Tp calculated based on a parameter participating in the quantity of air sucked in an engine by a feedback correction coefficient LAMBDA set by proportional-­integrating control or the like based on a signal from an air/fuel ratio sensor and the air/fuel ratio is feedback-­controlled to an aimed air/fuel ratio, according to the present invention, the deviation of the feedback correction coefficient LAMBDA from the reference value during the air/fuel ratio feedback control is learned to determine a learning correction coefficient, and on computation of the fuel injection quantity Ti, the basic fuel injection quantity Tp is corrected by the learning correction coefficient and the base air/fuel ratio obtained from the fuel injection quantity computed without correction by the feedback correction coefficient LAMBDA is made in agreement with the aimed air/fuel ratio and during the air/fuel feedback control, the fuel injection quantity is computed by further correcting the air/fuel ratio by the feedback correction coefficient. In the present invention, the above-mentioned learning correction coefficient is divided into an indiscriminate learning correction coefficient K ALT for learning deviation by the change of the air density with respect to all the areas of the engine driving state mainly for correction of the deviation by the altitude and an area-­wise learning correction coefficient k MAP for learning the deviation by dispersion of a part or the like for the respective area, and the fuel injection quantity Ti is computed, for example, according to the formula of Ti = Tp (LAMBDA + K ALT + K MAP ). On the other hand, under conditions where only the deviation by the change of the air density can be learned, that is, in the region where no deviation in the system is caused by the change of the throttle valve opening degree and the sucked air flow quantity is not substantially changed by the change of the throttle valve opening degree at any engine rotation number (Q flat region), the deviation by the change of the air density is indiscriminately learned and the indiscriminate learning correction coefficient K ALT is rewritten, and in the other region , the deviation by dispersion of a part is learned for the respective areas and the area-wise learning correction coefficient K MAP is rewritten.
