摘要: A reagent dosing system (10) for an internal combustion engine having an exhaust pipe (20) and a pump are disclosed. The reagent dosing system (10) comprises a first pump (26) having input means (30) for receiving reagent from a reagent supply (22) and output means (32) for delivering the reagent to a supply line (28), and a fluid dosing device (12) downstream of the first pump (26), comprising a nozzle (16) and a second pump (14) for receiving the reagent from the supply line (28) and for delivering the reagent to the nozzle (16), the second pump (14) being operable to increase the pressure of the reagent in the nozzle (16) to an injection pressure so as to cause delivery of the reagent through the nozzle (16). The first pump (26) is operable to increase the pressure of reagent in the supply line (28) to a pressure that is less than the injection pressure so as to guard against overheating of the reagent in the supply line (28). A pump (100) according to the invention is arranged such that, when the pump is not operating, an outlet valve means (135) of the pump is held in an open position so as to allow reagent to flow from the inlet means (102) to the outlet means (104) through the pumping arrangement (108, 154).

A control chamber (184) for fuel is provided, preferably at least in part, between the first valve needle and the second valve needle, wherein movement of the first valve needle is responsive to fuel pressure in the control chamber, and wherein movement of the second valve needle is coupled to a first actuator arrangement (159), such that when the second valve needle lifts away from the second seating region, a fuel flow path is established between the control chamber and the second set of nozzle outlets. The fuel injector further includes a second actuator arrangement (200) that is operable to control fuel flow into the control chamber thereby regulating fuel pressure within the control chamber and, thus, movement of the first valve needle.

摘要: A dosing device (1) is provided that is suitable for administering a reagent (2) into an exhaust chamber (4) of an internal combustion engine. The device (1) comprises a nozzle body (6) and an insulating jacket (5) wherein the jacket (5) is mounted to the nozzle body (6) at one or more mounting points (8,9), and wherein the dosing device (1) is adapted to engage with a port (10) located in the wall of an exhaust chamber (4). The insulating jacket (5) defines a compartment (11), which can comprise an insulating material or can be substantially evacuated. The dosing device (1) of the invention is advantageously insulated from the elevated temperatures in the surrounding environment, thereby allowing for the reagent to be maintained at an optimal working temperature range.
