Beschreibung
Zusammenfassung:	A direct injector unit includes a fuel pipe and injectors fixed to the fuel pipe. The direct injector unit is assembled to a cylinder head by: mounting the cylinder head in a predetermined posture; holding the direct injector unit while positioning a reference injector and guiding remaining injectors such that their leading end portions are movable; and inserting the injectors into injector mounting holes of the cylinder head by relatively moving the direct injector unit toward the cylinder head in a state in which the reference injector is positioned with respect to a corresponding injector mounting hole.
