A nozzle insert that is capable of being irreversibly attached to a needle valve tube such that the resulting needle valve member can be used in a nested needle valve configuration for a dual mode fuel injector.

Nozzle insert for dual mode fuel injector

A fuel injector includes a homogenous charge nozzle outlet set and a conventional nozzle outlet set controlled respectively by inner and outer needle value members. The homogenous charged nozzle outlet set is defined by an outer needle value member that is moveably positioned in an injector body, which defines the conventional nozzle outlet set. The inner needle valve member is positioned in the outer needle valve member. The outer needle valve member is a piece component that includes at least one external guide surface, an external value surface and an internal valve seat.
