Abstract: A method of determining a minimum drive pulse (MDP) for an injector (7) in a fuel system (1) within an engine, the injector being associated with a source of pressurised fuel (4), the method comprising: (a) sending a drive pulse of a first length to the injector; (b) determining an expected pressure in the fuel system at a given time; (c) measuring an actual pressure in the fuel system at the given time; (d) determining if an injection event has occurred by comparing the expected and actual values; (e) repeating steps (a) to (d) with drive pulses of progressively increasing lengths until an injection event has occurred and setting the drive pulse length associated with the injection event as the MDP of the injector.

Abstract: 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.
