Abstract (en)
[origin: WO2011087430A1] The invention relates to a method for warming a reductant in an SCR system which comprises a container (205) for said reductant and a dosing unit (250). The method comprises the step of extracting at least part of said reductant from said container (205) and warming said at least part by means of at least one warming element (261; 262; 263; 264; 265) outside said container (205). The method further comprises the step of returning the warmed part of said reductant to the container (205) before dosing of said warmed part via the dosing unit (250) commences in the SCR system. The invention relates also to a computer programme product comprising programme code (P) for a computer (200; 210) for implementing a method according to the invention. The invention relates also to a device and to a motor vehicle which is equipped with the device.
