摘要： The invention relates to a method pertaining to an SCR system which comprises a feed device (230) to supply reducing agent to a dosing device (250) from a container (205) for reducing agent, which dosing device (250) comprises a valve configuration (320) and an expansion section (310) and heating devices (200, 210; 270, 290). The method comprises the step of - warming (s430) said dosing device (250), before the supply of reducing agent to said dosing device (250) is switched off, to such an extent that when reducing agent freezes in said dosing device (250) the freezing process is controlled so that expansion due to the freezing of reducing agent in said dosing device (250) takes place substantially in said expansion section (310). 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 an SCR system and a motor vehicle equipped with the SCR system.

摘要： A system arranged to carry out a systematic selection of a specification for a first vehicle, where the said specification comprising several parameters related to at least one characteristic for the said first vehicle is presented. The system according to the present invention comprises a collection device arranged for the collection of operational data from at least one other vehicle, where the said operational data comprise information about how the said at least one other vehicle has been used. The system further comprises a simulation device arranged to simulate how an adjustment of at least one of the said several parameters impacts the said at least one characteristic for the said first vehicle, where the said simulation is based on the said operational data. Further, the system comprises a selection device arranged for the selection of at least one specification based on the said simulation.
