制御装置。[Scope of Claim for Utility Model Registration] a. An intake air amount detection means for detecting the amount of intake air; b. A rotation speed detection means for detecting the rotation speed of the engine; c. An opening degree detection means for detecting the opening degree of the throttle valve; d air amount calculation means for calculating the amount of intake air based on the opening degree of the throttle valve and the rotational speed of the engine; e transient state determination means for determining the transient state of the engine from changes in the opening degree of the throttle valve; f intake air amount The amount of fuel supplied to the engine is set based on the amount of air detected by the detection means, and when setting, the amount of fuel supplied is set so that the target air-fuel ratio is leaner than the stoichiometric air-fuel ratio in at least a part of the operating range. At the same time, when the engine is in a lean air-fuel ratio operating region and shifts to a predetermined transient state, the fuel supply amount is determined based on the air amount calculated by the air amount calculation means instead of the detected value of the intake air amount detection means. A fuel supply control device for an internal combustion engine, comprising: supply amount setting means for calculating; and fuel supply means for supplying fuel based on the output of the supply amount setting means.
