摘要：
A method for externally adjusting the axial length of a solenoid actuated fuel injector includes the step of externally forming a helical scribe mark in a housing component, thereby changing the axial length of the injector. By adjusting the length of the helical scribe mark and the depth of the scribe mark, and by measuring the stroke or the flow rate of the injector, the stroke or the flow rate of injector may be set precisely. The external adjustment of the length of the housing component may be made in cartridge form as well as in final assembly form of the fuel injector complementing the manufacturing process versatility.
