Definitions
- a method for providing variable fuel dispersal through a fuel injector nozzle comprising: providing a first plurality of openings in an outer housing of the fuel injector nozzle; providing a second plurality of openings in the outer housing of the fuel injector nozzle, the second plurality of openings being disposed below the first plurality of openings and the second plurality of openings are larger than the first plurality of openings such that a larger amount of fuel is allowed to flow therethrough; moving an outer needle from a first position to a second position in accordance with a first mode of dispersal of fuel through the fuel injector nozzle, wherein fuel under pressure is only allowed to flow through the first plurality of openings; and moving the outer needle from the second position to a third position in accordance with a second mode of dispersal of fuel through the fuel injector nozzle, wherein fuel under pressure is allowed to flow through the first plurality of openings and the second plurality of openings wherein fuel flowing through the second plurality of openings collides with fuel flowing through the first pluralit
- One exemplary embodiment of the present invention is to provide a fuel injector with a variable area nozzle that produces colliding sprays in one spray position optimized for normal diesel combustion and a non-colliding spray configuration wherein only a smaller set of opening are used for fuel dispersal wherein the spray geometry and flow rate is adapted for other emission technologies such as Homogeneous Charge Compression Ignition (HCCI) or injection of the fuel when the piston is at or near bottom dead center or any other position other than top dead center.
- HCCI Homogeneous Charge Compression Ignition
- first outer valve needle 18 to control fluid communication between chamber 22 and a plurality of first outlet openings 24 bored through a nozzle end 26 of nozzle body 12.
- first outlet openings 24 will have a smaller diameter opening than the openings disposed below openings 24 and the angular configuration of openings 24 is adapted for supplemental injection requirements.
- the diameter of openings 24 is 0.011 mm and the diameter of openings 48 is 0.016 mm. It is, of course, understood that exemplary embodiment of the present invention are intended to include dimensions greater than or less than the aforementioned values.
- the number of openings 48 will be the same as the number of openings 24. However, in an alternative exemplary embodiment, and wherein the positioning and size of openings 48 allows the same to collide with fuel from more than one opening 24, the number of openings 48 may be less than the number of openings 24. Likewise the number of openings 24 may be less than the number of openings 48, but in all cases an opening 48 will be paired with an opening 24 as they may exist.
