Abstract: A liquid tank includes a tank wall enclosing a tank volume and at least one relief structure facing the tank volume on an inner side of the tank wall. The relief structure is formed as one-piece with the tank wall. Two shell parts can be joined along a joining surface to make a section of the tank wall. One of the shell parts can include a tank bottom. At least one part of the relief structure can be formed on the tank bottom. The relief structure can include projections protruding into the tank volume along a local direction of projection.

Abstract: An automotive service liquid tank for receiving a service liquid of a motor vehicle, in particular an aqueous urea solution, has a tank wall that encloses a tank volume on the inside of the tank, wherein the tank has locally, by comparison with at least one other tank region, at least one region with enhanced thermal insulation, in order to influence a freezing behavior of the service liquid received in the tank in such a way that the service liquid, when the outside temperature drops, freezes later in the tank region with enhanced thermal insulation than in the at least one other tank region without enhanced thermal insulation. According to the invention it is provided that the enhanced thermal insulation is formed integrally with the tank wall.

Abstract: An operating fluid storage system for a motor vehicle having a reservoir with a filling opening and a closure cover which closes the filling opening and which can be removed from said filling opening to release the filling opening, and with at least one operating fluid outlet opening, to which an operating fluid conveyor line can be connected, for the output of operating fluid to a consumer, the system having a need sensor assembly and an output device, the need sensor assembly determines a filling need of the reservoir and outputs a corresponding need signal to the output device which acoustically, visually and/or haptically outputs a signal indicating the filling need; on the reservoir, an identification device is provided, which can be switched between at least two functional states and which is connected to the need sensor assembly via signal transmission, and which, when the need sensor assembly determines a filling need of the reservoir, is actuated by a corresponding need signal of the need sensor asse
