置。[Scope of Claim for Utility Model Registration] (1) Engine operating state detection means for detecting the operating state of the engine, setting a fuel injection amount according to the engine operating state, and outputting an injection signal corresponding to the fuel injection amount. A fuel injection amount setting means, an exhaust temperature detection means for detecting the temperature of engine exhaust gas, and a correction injection amount setting means for outputting a correction injection signal corresponding to a correction fuel injection amount that is set to increase or decrease according to the detected exhaust gas temperature. and pulse output means for outputting a fuel injection pulse obtained based on the outputs of the fuel injection amount setting means and the corrected injection amount setting means, and driving a fuel injection valve in accordance with the pulse output from the pulse output means. An electronically controlled fuel injection device for an internal combustion engine, comprising: a drive means; (2) Registration of a utility model characterized in that the corrected injection amount setting means outputs a corrected injection signal so that the air-fuel ratio is such that the maximum output of the engine is obtained when the detected exhaust temperature is below a predetermined allowable temperature. An electronically controlled fuel injection device for an internal combustion engine according to claim 1. (3) Registration of a utility model characterized in that the correction injection amount setting means outputs a correction injection signal for correcting the air-fuel ratio to the rich side when the detected exhaust gas temperature exceeds a predetermined allowable temperature. An electronically controlled fuel injection device for an internal combustion engine according to claim 1 or 2. (4) Utility model registration claims 1 to 3, characterized in that the corrected injection amount setting means outputs a corrected injection signal only in a predetermined operating state detected by the engine operating state detecting means. An electronically controlled fuel injection device for an internal combustion engine according to any one of the items.
