Title: Dual mode fuel injection system and fuel injector for same

Abstract

A fuel injection system has the ability to produce two different spray patterns depending on the positioning of a needle control valve member. Positioning of the needle control valve member determines which of the two needle control chambers are placed in a low pressure condition. First and second needle valve members have closing hydraulic surfaces exposed to fluid pressure in the two needle control chambers. The injector preferably includes a homogenous charge nozzle outlet set and a conventional nozzle outlet set controlled respectively, by the first and second needle valve members.
