Method for armature lift feedback setting of injector

Abstract

A method for controlling an armature lift feedback setting of an injector for a vehicle includes a primary lift that is formed by deforming a positioning ring or a stopper through a primary laser welding in a circumferential direction with a lower end portion of the positioning ring or an upper end portion of the stopper as a first welding portion, and a target lift may be reached through a secondary welding in the circumferential direction performed by a number of weldings set according to a tolerance range of the primary lift with respect to the target lift with a middle portion of the positioning ring or the stopper as a secondary welding portion. The method further includes adjusting the number of weldings according to a variable laser output, thereby precisely obtaining armature lift dispersion with respect to the positioning ring or the stopper.
