御装置。[Scope of Claim for Utility Model Registration] (a) Operating state detection means for detecting the operating state of the engine; (b) A fuel cut signal is output when the engine shifts to a predetermined deceleration state, and when the engine reaches a predetermined recovery rotation speed. a signal generating means that stops outputting the fuel cut signal and outputs the fuel cut signal again when the engine exceeds the recovery rotation speed after the output of the fuel cut signal is stopped and the amount of change in the engine rotation speed tends to increase; (c) supply amount calculation means that calculates the fuel supply amount based on the operating state of the engine and outputs a supply signal, and stops outputting the supply signal when a fuel cut signal is input; 1. A fuel supply control device for an internal combustion engine, comprising: a fuel supply means for supplying fuel to an engine based on the fuel supply means;
