A fuel injector that provides fuel targeting and fuel spray distribution with non-angled metering orifices at higher than normal fuel flow rates is described. In a preferred embodiment, the fuel injector includes a housing, an inlet, an outlet, a seat, a metering disc, and a closure member. The seat is disposed proximate to the outlet and includes a sealing surface and a seat orifice extending through the seat from the sealing surface along the longitudinal axis to a tapered surface that extends obliquely from the seat orifice about the longitudinal axis to define a first volume. The metering disc includes a first surface disposed about the longitudinal axis and having a portion contiguous to a plane and a second surface that extends from the first surface away from the inlet and bounds a portion of the plane to define a second volume. The plurality of metering orifices is located outside a projection of the seat orifice that defines a first virtual circle on the second surface. A method of flowing fuel through the fuel injector is also described.

A method and apparatus for measuring and controlling the temperature of fuel inside a fuel injector is provided. A first resistive element having a resistance that varies with temperature is positioned proximal the fuel within a fuel injector and a second resistive element having a known resistance is placed in series with the first resistive element and connected at a node. When a known voltage is applied across the resistor-divider network, the voltage generated at the node corresponds to the temperature of the fuel within the fuel injector. The first resistive element may also be used to heat the fuel within the injector to a predetermined temperature. Logic circuitry prevents energizing the first resistive heating element if any fuel injector coils are energized, thereby ensuring full voltage is available to drive the fuel injector coils.

A fuel injector includes a common coil that both actuates a pole-piece and provides inductive heating to a fuel flow path. In one example, a first magnetic field is generated to move the pole-piece in response to a DC signal. A structure within the fuel injector near the fuel flow path is excited and heated in response to a AC signal to the coil that generates a second magnetic field.

Multiple orifice disks are stacked and include one or more swirl disks. The effect of the stack of disks is to impart swirl to the fuel stream being ejected from the injector in a relatively short axial length. The geometry of the disks in the stack are such that the fuel from the top disk enters the bottom disk at the end of a pattern which operates to impart a swirl component to the fuel. The pattern in the bottom disk is typically a two layered pattern wherein the top layer is one half the thickness of the thin disk and the bottom layer is the second half of the thickness of the thin disk.

A fuel injector for an internal combustion engine includes a valve body. A valve seat is associated with the valve body. The valve seat defines an outlet opening through which fuel may flow. An armature is associated with the valve body and is movable with respect to the valve body between a first position and a second position. The armature is associated with a closure member proximate the outlet opening and contiguous to the valve seat when in the first position, and spaced from the valve seat when in the second position. An electromagnetic coil is energizable to provide magnetic flux that moves the armature between the first and second positions to control liquid fuel flow through the outlet opening. A heating coil is energizable to provide heat and thereby vaporize liquid fuel as it exits the outlet opening.

A thin disk orifice member having fuel metering orifices located on flat planar surfaces extending from the disk surface, The flat planar surfaces from sides of an enclosed structure having three or more sides, The structure may be in one position extending from the disk surface in the direction of the outlet of the injector or may be inverted. The orifices direct the fuel flow in various streams or sprays to individual cylinders of the engine.

A heated tip fuel injector includes a housing having a bore formed therein for receiving fuel under pressure; a valve seat mounted at one end of the housing, the valve seat including an orifice; a needle valve having one end mounted to an armature and another end which contacts the valve seat to close off fuel outflow from the bore and which is lifted from the valve seat to inject fuel; a heater disposed in the housing upstream of the valve seat and extending around the needle valve; and at least one flow disturbing element disposed upstream of the heater. The flow-disturbing element enhances heat transfer from the heater to the fuel.
