ABSTRACT:
BACKGROUND OF THE INVENTION
It is believed that examples of known fuel injection systems use an injector to dispense a quantity of fuel that is to be combusted in an internal combustion engine. It is also believed that the quantity of fuel that is dispensed is varied in accordance with a number of engine parameters such as engine speed, engine load, engine emissions, etc.
It is believed that examples of known electronic fuel injection systems monitor at least one of the engine parameters and electrically operate the injector to dispense the fuel. It is believed that examples of known injectors use electromagnetic coils, piezoelectric elements, or magnetostrictive materials to actuate a valve.
It is believed that examples of known valves for injectors include a closure member that is movable with respect to a seat. Fuel flow through the injector is believed to be prohibited when the closure member sealingly contacts the seat, and fuel flow through the injector is believed to be permitted when the closure member is separated from the seat.
It is believed that examples of known injectors include a spring providing a force biasing the closure member toward the seat. It is also believed that this biasing force is adjustable in order to set the dynamic properties of the closure member movement with respect to the seat.
It is further believed that examples of known injectors include a filter for separating particles from the fuel flow, and include a seal at a connection of the injector to a fuel source.
It is believed that such examples of the known injectors have a number of disadvantages.
It is believed that examples of known injectors must be assembled entirely in an environment that is substantially free of contaminants. It is also believed that examples of known injectors can only be tested after final assembly has been completed.
SUMMARY OF THE INVENTION
According to the present invention, a fuel injector can comprise a plurality of modules, each of which can be independently assembled and tested. According to one embodiment of the present invention, the modules can comprise a fluid handling subassembly and an electrical subassembly. These subassemblies can be subsequently assembled to provide a fuel injector according to the present invention.
The present invention provides a method of setting armature lift in a fuel injector. The method comprises providing a tube assembly, providing a seat assembly having a seating surface, connecting the seat assembly to the second valve body end, and adjusting the distance between the first tube assembly end and the seating surface. The tube assembly includes an inlet tube assembly having a first tube assembly end; a non-magnetic shell having a first shell end and a second shell end, the first shell end being connected to the first tube assembly end; and a valve body having a first valve body end and a second valve body end, the first valve body end being connected to the second shell end.
