Claims

[Scope of Claim for Utility Model Registration] 1. Basic fuel amount determining means for determining the basic amount of fuel to be supplied to the internal combustion engine according to the load of the engine, and detecting the throttle valve opening and controlling the detected throttle valve opening. an acceleration determining means for determining an accelerated operating state and a post-acceleration operating state of the engine based on a degree of change in speed; and when the acceleration determining means determines that the engine is in an accelerated operating state;
a correction amount determining means for determining an acceleration fuel correction amount in accordance with a change in the throttle valve opening; and a correction amount determining means for determining an acceleration fuel correction amount when the acceleration determining means determines that the engine is in an operating state after acceleration. a correction amount gradual reduction means for gradually decreasing the value at the end of the acceleration driving state; and a basic fuel correction for adding an acceleration fuel correction amount determined by the correction amount determining means or the correction amount gradual reduction means to the basic fuel amount. and a fuel supply control device for an internal combustion engine, characterized in that the degree of gradual reduction of the acceleration fuel correction amount gradually reduced by the correction amount gradual reduction means is set according to a change in the basic fuel amount. Fuel supply control device. 2. The fuel supply control device for an internal combustion engine according to claim 1, wherein the degree of gradual reduction of the acceleration fuel correction amount gradually reduced by the correction gradual reduction means is set to be larger as the degree of increase in the basic fuel amount is larger.
