摘要： In a method for the model-based determination of the temperature distribution of a post-treatment unit for exhaust gas, steady-state and non-steady-state operating states are differentiated by taking into account the axial and radial temperature distributions, and in particular the radial transfer of heat to the surroundings is taken into account in the model-based determination for steady-state operating states by means of a coefficient R
c of the transfer of heat, and for non-steady-state operating states the transfer of heat from the exhaust gas flowing axially through the post-treatment unit to the segments is taken into account by means of a heat transfer coefficient k, on the basis of virtual segmentation of the post-treatment unit in the model-based determination.摘要翻译： 在用于基于模型的废气后处理单元的温度分布测定方法中，通过考虑轴向和径向温度分布，在稳定运行状态和非稳定运行状态之间进行区分， 在后处理单元的虚拟分割的基础上，特别是在基于模型的稳定运行状态的确定中考虑到周围的径向热传递，并且对于非稳定运行状态，来自排气的热传递 通过传热系数k考虑通过后处理单元轴向流到段的气体。

摘要： The invention relates to a supply system (1) for supplying urea, in particular for an exhaust-gas purification device for the treatment of exhaust gases of an internal combustion engine, having a storage vessel (5) for the medium, having a dosing device (7) for dosing the medium in particular into an exhaust line (3) of an internal combustion engine, and having a supply line (9) which comprises a feed line (11) for supplying the medium to the dosing device (7) and a return line (13) for returning the medium from the dosing device (7) into the storage vessel (5), wherein the dosing device (7) is designed such that, during the operation of the supply system (1), for the purpose of cooling of the medium, flow can be caused to pass through said dosing device from a feed port (17) to a return port (19) of the dosing device (7). It is provided here that the supply line (9) comprises an additional fluid connection (23), such as a bypass, between the feed line (11) and the return line (13), wherein the additional fluid connection (23) issues into the feed line (11) upstream of the feed port (17) of the dosing device (7) and issues into the return line (13) downstream of the return port (19) of the dosing device (7). In this way, damage caused by elevated thermal loading in the event of the fluid circuit being blocked by frozen fluid in the region of the storage vessel is prevented.

摘要： In a method for regenerating a particle filter, a triggering limit is specified, namely in the form of a pressure difference Δp
trigger across the particle filter (4), which pressure difference results for a particular working interval (A - E) from the ash formation at the end of the regeneration period of the preceding working interval and a standardized loading pressure difference Δp
standardized , if the regeneration is not triggered in advance according to time.
