<p>PROBLEM TO BE SOLVED: To suppress a variation of an engine rotation speed when changing a fuel injection amount in order to complete learning processing within a learning area in which the learning processing of a learning value is not completed, and the lowering of drivability resulting from the variation.SOLUTION: A learning value for correcting a fuel injection amount is set at each of a plurality of learning areas which are categorized according to the fuel injection amount from an injector 6 of an internal combustion engine 1, and the learning processing of the learning value is performed at each learning area so that the learning value compensates for displacement from a proper value of the fuel injection amount. When there exists a learning area in which the learning processing of the learning value is not completed, forcible learning processing for completing the learning processing is performed. In the forcible learning processing, the fuel injection amount of the injector 6 is adjusted to a value within the learning area in which the learning processing is not completed by adjusting a flow-in amount of evaporation fuel to a suction passage 2 by an evaporation fuel processor, and the learning processing of the learning value in that learning area is performed.</p> |
