Abstract (en)
[origin: WO2011162698A1] The invention relates to a method pertaining to an HC dosing system for cleaning of exhaust gases from an engine (150) which comprises a dosing unit (250) to supply a fuel to an exhaust duct (240), comprising the step of determining (s340) whether there is an undesired temperature level of said dosing unit (250). The method comprises also the step, if it is found that there is said undesired temperature level, of removing (s360) warmed fuel from said dosing unit (250) by supplying it to said exhaust duct (240), which entails - calculating (s350) and removing an amount of fuel which is removable on the basis of a prevailing temperature of the dosing unit (250), or - removing (s360) a predetermined amount in the form of substantially all of the warmed fuel of the dosing unit (250) from it to said exhaust duct. The invention relates also to a computer programme product containing programme code (P) for a computer (200; 210) for implementing a method according to the invention. The invention relates also to a device and a motor vehicle (100) which is equipped with the device.
