摘要： A dosing valve for administering a reducing agent into an exhaust stream within an exhaust manifold of an internal combustion engine. The dosing valve includes a valve needle internally coaxial to a valve body and held in a closed position by a force of compressed spring acting axially and held in relation to the valve needle and valve body. The negative impact of varnish and dehydrogenated compounds, or coking products, of hydrocarbon based reducing agents, is substantially reduced or eliminated. Additionally, this includes decreased sensitivity to the negative impact of the precipitates and crystals that come out of the solution due to temperature change with urea-based reducing agents.

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.

An armature structure (14, 16) can move with respect to the solenoid assembly from a closed position, defining a working gap area (62) between the coil and a portion of the armature structure, to an open position in response to the magnetic field generated by the coil. Seal structure (22) is coupled with a proximal end of the armature structure and has a sealing edge (28) to seal with a component when the armature structure is in the closed position thereof. A spring (44) biases the armature structure to the closed position.

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.
