  • Patent number: 9243596
    Abstract: A flow control valve (15) for a direct injection pump (10) has an inlet end (12), an inlet valve (26), a compression chamber (48), a pump piston (14), and an outlet (13). The valve (15) has a housing (16) and a non-electrically operated control plunger (22) movable within the housing. The control plunger engages with and disengages from the inlet valve to control opening and closing of the inlet valve. A spring (28) biases the control plunger away from the inlet valve. The pump and housing define port structure (38, 44) fluidly connecting the outlet with a volume (42) that communicates with the control plunger such that when fluid pressure at the outlet is greater than a certain value, the fluid pressure in the volume alone causes the control plunger to move against the spring and engage the inlet valve to hold the inlet valve in an open position.

  • Publication number: 20140054394
    Abstract: A reductant delivery unit (RDU) delivers supplied reductant (aqueous urea solution) to the engine exhaust system. The delivered reductant is transformed into ammonia which then reacts with the exhaust oxides of nitrogen in a catalytic environment to produce nitrogen and H20. The reductant must be metered to coincide with the amount of NOx present in the exhaust, and also present sufficient spray quality of the delivered fluid to promote good mixing of the ammonia with the exhaust gas. The RDU is a liquid-cooled, making the RDU suitable for very high temperature environment applications.

  • Publication number: 20080029199
    Abstract: Methods of forming a hermetic seal between fuel system components are provided. One of the methods can be achieved by passing a light beam through a wall of a polymeric member to an inner surface of the wall that surrounds an outer surface of a polymeric body and defines an internal passage for a flow of fuel; and welding the inner surface of the polymeric member to the outer surface of the polymeric body to provide a hermetic seal at the respective inner and outer surfaces against the flow of fuel. Another method can be achieved by disposing an adhesive on an inner surface of polymeric member that surrounds an outer surface of a polymeric body and defines an internal passage for a flow of fuel; and activating the adhesive to bond the polymeric member to the polymeric body.

  • Publication number: 20080022668
    Abstract: A dosing valve assembly is disclosed for administering a reducing agent into an exhaust stream from an internal combustion engine upstream of a catalytic converter and diesel particulate filter. The dosing valve assembly includes a control valve coupled to a source of reducing agent, a delivery valve constructed and arranged for coupling to the exhaust stream to enable a quantity of reducing agent to be administered into the exhaust stream, and an elongated conduit connecting the control valve and delivery valve for fluidly communicating reducing agent from the control valve to the fuel delivery valve. The disclosed arrangement enables the control valve to be displaced from the delivery valve and thus away from the high temperature environment proximal to the exhaust stream.

  • Publication number: 20070235557
    Abstract: A fuel injector for an internal combustion engine includes a valve body 14. A valve seat 18 is associated with the valve body. The valve seat defines an outlet opening 24 through which fuel may flow. An armature 38 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 24 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 44 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 50 is energizable to provide heat and thereby vaporize liquid fuel as it exits the outlet opening.

  • Publication number: 20070235569
    Abstract: 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.

  • Publication number: 20050132572
    Abstract: Various methodologies relating to a polymeric fuel injector are disclosed. One method provides for manufacturing the fuel injector by forming a polymeric housing over a coil assembly and electrical connectors to provide a polymeric passage extending from an inlet to an outlet along a longitudinal axis; inserting components into the polymeric passage from at least one of the inlet and outlet; and securing a polymeric support member of a metering assembly to the housing. Another method provides for manufacturing a fuel injector housing by hermetically enclosing a polymeric housing over a coil assembly and electrical connectors to provide a continuous polymeric passage, the polymeric passage directly facing the longitudinal axis. Yet another method provides for manufacturing a metering assembly by providing a seat; and molding at least a portion of the seat to provide a polymeric support member that surrounds the outer circumference of the seat.
