PROBLEM TO BE SOLVED: To optimize fuel supply quantity and injection timing in a gasoline-replacing fuel injection system using a gasoline injection system. SOLUTION: In a gasoline-replacing fuel injection system adding an injector 2 for non-gasoline fuel and an electronic control unit 11 for non-gasoline fuel injection control receiving gasoline injection signal output according to engine operation condition and calculating injection quantity of non-gasoline fuel on a gasoline injection system existing on an engine provided with an electronic control unit 10 for gasoline injection control and various sensors 5-9 detecting engine operation conditions, the electronic control unit 11 directly calculates injection quantity of non-gasoline fuel based on data of an engine operation condition without using gasoline injection signal, outputs fuel injection signal to the injector 2 and executes independent control when the engine gets in the predetermined operation condition.
