    Abstract: A fluid dosing device for introducing a reagent into an exhaust gas flow in a selective catalytic reduction system is described. The dosing device comprises an injection nozzle (26) having an outlet end (30) from which the reagent is injectable into the gas flow (38), and a heat shield (240) disposed around the outlet end (30) of the injection nozzle (26) and arranged to shield the outlet end (30) from the exhaust gas flow (26), in use. The heat shield (240) comprises an outlet aperture (244) through which the reagent can pass into the gas flow (38) during injection of the reagent. According to the invention, the heat shield (240) further comprises gas flow modifying means (250) arranged to guard against deposition of the reagent between the injection nozzle (26) and the heat shield (240), thereby reducing the likelihood of thermal bridging between the heat shield and the injection nozzle.

    Abstract: A method of dosing a reagent into an exhaust gas stream of an internal combustion engine (3) having an SCR catalyst, the method comprising injecting reagent from a reagent tank (20) into the exhaust gas stream at a position upstream of the SCR catalyst 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 (20) into the exhaust gas stream at a position upstream of the SCR catalyst 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. The method further comprises sensing the level of reagent in the reagent tank (20); and halting the first dosing schedule when the sensed level of reagent drops below a predetermined level.
