摘要： A method of dosing a reagent into an exhaust gas stream of an internal combustion engine (3) having an SCR catalyst (13), the method comprising injecting reagent from a reagent tank (21) into the exhaust gas stream at a position upstream of the SCR catalyst (13) using a reagent injector (40) in accordance with a first dosing schedule in order to remediate a predetermined proportion of NOx in the exhaust gas stream, the first dosing schedule being associated with a first range of engine operating conditions; and injecting reagent from the reagent tank (21) into the exhaust gas stream at a position upstream of the SCR catalyst (13) using a reagent injector (40) in accordance with a second dosing schedule in order to enable heat transfer between the reagent injector (40) and said injected reagent, the second dosing schedule being associated with a second range of engine operating conditions. Dosing in accordance with said first or said second dosing schedule is carried out in dependence on whether engine operating conditions lie within said first or said second range of engine operating conditions, and the proportion of NOx in the exhaust gas stream which is remediated by dosing using said second dosing schedule is less than said predetermined portion. A reagent dosing system (1) is also provided for dosing a reagent into the exhaust gas stream of an internal combustion engine (3), comprising a reagent tank (21) for storing a supply of reagent, an injector module (40) comprising an atomising dispenser (42) and a positive-displacement metering pump (41) which draws reagent from the reagent tank (21) and delivers it to the dispenser (42) a supply line (35) coupling the reagent tank (21) to the injector module (40), and a dosing control unit (70) operable to control the injector module (40) to inject reagent into the exhaust gas stream. A priming pump (80) is provided to urge reagent along the supply line (35) toward the injector module (40) under selected conditions.

摘要： The invention relates to a pressurized fuel injector (10) including a tubular body (12) extending along a longitudinal axis (Z) and forming, at one end, a nozzle (16). Fuel (C) flows in the body (12) between an inlet (14) and the nozzle (16). Said injector also includes a needle (18) which is axially arranged in the body (12) and capable of moving between an open nozzle position (PO) and a closed nozzle position (PF). The fuel (C) flows in the space (E) between the needle (18) and the inner surface of the body (12). The needle (18) is controlled according to a difference in the pressure between a first control chamber (22), into which the upstream end (20) of the needle (18) leads, and the nozzle (16) which is located downstream. The pressure in the first control chamber (22) is controlled by a control valve (32) controlled by an electromagnet. Said pressurized fuel injector (10) is characterized in that it is moreover provided with a complementary means (52, 54, 40, 38, 44) for controlling the needle (18), wherein said means engages with the first control chamber (22) such that the pressure of the fuel (C) at the inlet (14) is entirely transmitted to the injection nozzle (16).
