摘要： A fuel injector assembly includes a first coil that induces a time varying magnetic field into a second coil that is utilized to heat fuel flowing through the fuel injector. A first coil receives a first signal from a driver to generate a first magnetic field that moves an armature between an open and closed position. The second coil generates a second magnetic field generated by a current induced by the first coil into the second coil. The induced current is generated by an alternating current signal that is interposed onto a direct current signal sent to the first coil. The alternating current signal produces a time varying second magnetic field that induces heating of a magnetically active component with the fuel flow that in turn heats the fuel.

摘要： A fuel injector assembly includes a first coil driven by a direct current driver and a second coil driven by an alternating current driver where both the first coil and the second coil share a common connection to reduce the number of external terminal connections. The second coil generates a second magnetic field that is utilized to heat a component in thermal contact with the fuel flow that in turn heats fuel before exiting the fuel injector.

摘要： A fuel injector assembly includes a first coil that induces a time varying magnetic field into a second coil that is utilized to heat fuel flowing through the fuel injector. The second coil generates a second magnetic field generated by a current induced by the first coil into the second coil. The induced current is generated by an alternating current signal that is interposed onto a direct current signal sent to the first coil. The second coil also is electrically connected to pass current induced from the first coil into a component in thermal contact with the flowing fuel. The current from the secondary coil resistibly heats the component to provide an alternate mode of heating fuel flow.

摘要： The fuel injector nozzle injects fuel into the runner in a direction that may be either parallel or non-parallel to the co-axis of the fuel injector and its mounting socket, and the nozzle orifice from which the fuel is injected is disposed beyond an antechamber of the mounting socket so as to lie within the runner, hence injecting the fuel from the orifice at a location that does not lie within the antechamber of the mounting socket.

摘要： 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.

摘要： A fuel injector has an internal heater energized during cold starting 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 extend 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 on the outside of the heater.

摘要： A fuel injector is disclosed. The fuel injector has an upstream end, a downstream end, and a longitudinal axis extending therethrough. The fuel injector also has a body and a cylindrical needle. The needle is reciprocably located within the body between an open configuration adapted for permitting delivery of fuel from the downstream end and a closed configuration adapted for preventing delivery of the fuel from the downstream end. The fuel injector further includes a seat disposed proximate the downstream end. The seat includes a sealing surface engageable with the needle when the needle is in the closed configuration. The sealing surface has a seating diameter. The seat also includes a seat opening extending therethrough along the longitudinal axis. The seat opening has an opening diameter such that a ratio between the opening diameter and the seating diameter is less than 0.6. A method of generating turbulent flow in a fuel injector is also provided.
