In dual fuel engines, it is desirable to have injection of two distinct quantities of liquid fuel. Engines with these operating requirements have typically used two separate fuel injectors, or two separate nozzle assemblies, to satisfy this need.

In dual fuel engines, it is desirable to have injection of two distinct quantities of liquid fuel. Engines with these operating requirements have typically used two separate fuel injectors, or two separate nozzle assemblies, to satisfy this need. However, these systems can be rather complex and difficult to control. In addition, engineers have learned that fuel injectors having direct control have better performance which can increase engine efficiency. Therefore, the present invention addresses the needs of engines desiring injection of two distinct quantities of fuel, such as dual fuel engines, by utilizing a direct control fuel injector having a dual concentric check having separate orifices for the pilot and main injections.
