摘要

The invention relates to a reducing agent storage system (2) for a vehicle (4), which system comprises a reducing agent tank (6), a tapping container (8) intended for reducing agent and situated within the reducing agent tank (6), a tapping device (12) for reducing agent (10) connected to the tapping container (8), a return device (14) for reducing agent (10) connected to the tapping container (8), and a feed device (16) for reducing agent (10) which comprises a venturi pump (18) connected to the return device (14), which reducing agent storage system (2) is further provided with a warming device (30) for reducing agent (10), the feed device (16) being adapted to feeding reducing agent (10) from the reducing agent tank (6) to the return device (14) through a supply device (20) situated between them for reducing agent (10) by the venturi pump (18) drawing reducing agent (10) from the reducing agent tank (6) by means of the return flow (B) of reducing agent (10) which is led via the return device (14) to the tapping container (8), and the warming device (30) being a heating loop (32) in which liquid heat medium (36) warmed by the engine (34) of the vehicle circulates, which heating loop (32) is adapted to running within at least the lower portion (9) of the tapping container (8) and within at least the lower portion (7) of the reducing agent tank (6) and is also associated thermally with the venturi pump (18), making it possible for heat to be transferred from the liquid heat medium (36) to the reducing agent (10) in the reducing agent tank (6), the tapping container (8) and the venturi pump (18) in order to prevent freezing of the reducing agent (10). The invention relates also to a method for warming of reducing agent (10) in a reducing agent storage system (2) for a vehicle (4).
