FUEL INJECTION SYSTEM AND A MANUFACTURING METHOD THEREOF, PREVENTING A BOUNDARY BETWEEN A FUEL INJECTION PIPE AND A FUEL SUPPLY PIPE FROM BEING EASILY BROKEN AND PREVENTING FUEL FROM LEAKING TO THE OUTSIDE BY BREAKAGE

摘要

PURPOSE: A fuel injection system and a manufacturing method thereof are provided to prevent connection positions of a fuel supply pipe and a fuel injection valve from being easily broken by action of stress. CONSTITUTION: A fuel injection system(1A) comprises a tank in which fuel is stored; a supply pipe(2) including plural partition members(4,5) connected to each other and supplying fuel; and plural injection valves(3) connected to the supply pipe. Each injection valve comprises a cylinder(10) having a passage(12) pierced; a valve device(13) arranged in the cylinder to open and close the passage; and an actuator(14) driving the valve device. The cylinder is integrated with one of the partition members of the supply pipe.
