Method of positioning components of a modular fuel injector

摘要

A method of connecting a fuel group to a power group in a fuel injector comprising: manufacturing a fuel group including: providing a fuel tube assembly having a longitudinal axis extending therethrough; installing an orifice plate on the fuel tube assembly, the orifice plate having at least one opening disposed away from the longitudinal axis; rotating at least one of the power group and the fuel group such that the at least one opening is disposed at predetermined angle relative to a reference point on the power group; installing the fuel group in a power group, the power group having a generally axially extending dielectric overmold and a power connector extending generally radially therefrom; and fixedly connecting the fuel group to the power group; prior to rotating, a position of the at least one opening relative to the power connector can be identified by optical sighting.
