摘要： 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.

摘要： A method of preheating fuel in a fuel injector with an internal heater energized to reduce emissions. The heater being a ceramic hollow cylinder disposed within a valve body just upstream of a valve seat where fuel is injected through an orifice into the engine. Conductors for energizing the heater extend into the valve body and are sealed against the escape of pressurized fuel. In one version, the conductors are extended through an O-ring to be sealed. In another version the conductors include pins extending through the valve body sidewall with glass seals fused to the valve body and the pins. The conductors may comprise flat foil strips clamped between the O-ring and an elastomeric washer. The conductors also may be molded into the magnetic coil bobbin and sealed where the conductors emerge into the fuel cavity. The heater has metallized surfaces to create current flow through its wall thickness, and the conductors are electrically connected respectively to the inner end and outer surfaces of the hollow cylinder by metallization patterns enabling both mechanical contacts to be made on the outside of the heater.

摘要： A metering assembly for a fuel injector having multiple orifice plates is disclosed. The metering assembly includes a valve body, a seat, a needle and a multi-layer orifice plate assembly. The valve body has an inlet, an outlet and a longitudinal axis extending therethrough. The seat is disposed proximate the outlet and includes a passage having a sealing surface and an orifice. The needle is reciprocally located within the housing along the longitudinal axis between a first position wherein the needle is displaced from the seat, allowing fuel flow past the needle, and a second position wherein the needle is biased against the seat, precluding fuel flow past the needle. The multi-layer orifice plate assembly is located at the housing outlet and includes a first orifice plate having a plurality of first openings extending therethrough. The orifice plate assembly further includes a second orifice plate having a plurality of second openings extending therethrough. The plurality of first openings and the plurality of second openings are fluidly connected by at least one channel. A method of accelerating fuel through the injector is also disclosed.

摘要： The injector nozzle includes a cylindrical needle which is axially reciprocated by an armature assembly. The needle has a needle tip terminating in a flat end surface with a spherical transition surface between the flat end surface and the side walls of the needle. Depending upon the diameter of the needle and the included angle of the valve seat, the diameter of the flat end surface may be less than the diameter of the orifice through the valve seat. The circular edge defined between the flat end surface and the spherical transition surface defines a location where the liquid fuel and air consistently separate from the needle in the valve-open condition whereby variations in the spray cone angle and the flow rate are minimized during steady-state and transient operating conditions.
