を設けたことを特徴とするエンジンの制御装置。[Scope of Claim for Utility Model Registration] Operating state detection means for detecting the operating state of the engine, and a predetermined delay time from when the operating state of the engine shifts to a predetermined fuel increase region in response to an output from the operating state detection means. An engine equipped with an increase means for increasing the amount of fuel after the elapse of time, a knock sensor for detecting knocking, and a determining means for receiving an output from the knock sensor and determining whether or not the fuel used is regular gasoline based on the degree of occurrence of knocking. What is claimed is: 1. A control device for an engine, characterized in that the control device is provided with a prohibition means for prohibiting a determination by the determination means during a delay time of fuel increase by the fuel increase means.
