PROBLEM TO BE SOLVED: To minimize pressure drop in a hydraulic operating electronic control system by arranging an operation fluid supply device between a fluid rail and an injector, and thereby arranging the fluid rail near the injector. SOLUTION: A fluid rail 109 and a fluid rail support device are provided. The fluid rail 109 forms an operation fluid reservoir 124. An operation fluid outlet 129 connectable to an operation fluid inlet of an injector 104 is formed for the communication of the operation fluid. The fluid rail support device can be attached to an engine. When it is attached, the fluid rail 109 is arranged on an upper side of the operation fluid inlet of the injector 104 at the time of use.
