射装置。[Scope of Claim for Utility Model Registration] When starting an engine, the engine is equipped with a fuel supply control means that outputs a drive signal based on the operating state to an auxiliary fuel injection valve provided separately from the main fuel injection valve. In the injection device, a cold fuel control means outputs a drive signal that changes according to the temperature of the engine, and a drive signal from the fuel supply control means is cut off when the fuel supply control means becomes abnormal. An engine starting injection device comprising: a switching device for outputting a drive signal from the cold-time fuel control device to the auxiliary fuel injection valve.
