PROBLEM TO BE SOLVED: To easily synchronously operate them, even when a plurality of injectors are fitted to one cylinder for tune-up by providing a detecting part detecting the control signal from an injection control part and a synchronously controlled signal which generates part generating a synchronously controlled signal synchronizing with the control signal. SOLUTION: In a six-cylinder engine, of which each cylinder is provided with one of a first injector 20, when a second injector 20 is provided more on each cylinder, the respective first injectors 20 are connected together by the use of a control part 40 and wirings 3, the respective second injectors 30 are connected together by an assistant control device 1 and wirings 4. This assistant control device 1 is provided with input parts 1c for detecting control signals related to the injection actions of the first injectors 20, and constituted so as to generate synchronously controlled signals following the control signals input here from the control part 40. Hereby, even when injectors are provided addition for tune-up, the operation can be controlled properly.
