The invention relates to a filler neck (1) for an auxiliary liquid reservoir for a motor vehicle, in particular for a urea reservoir, having a neck housing (9), which defines a mouth hole stub (10) for a filler nozzle (7) and a filling channel (11) leading into the reservoir, wherein a receiving structure for a filler nozzle (7) is provided within the neck housing (9). At least one venting path, which is of enlarged cross section, at least in a section or sections, and of chamber-like or labyrinth-like design, is formed within the neck housing (9), allowing a venting flow parallel and counter to the refilling volume to flow through the neck housing (9) during refilling.

A controller calculates a period travel distance that is a travel distance of the vehicle from when the available travel distance is calculated to when the available travel distance is calculated next. The controller, when the remaining amount of urea aqueous solution inside a tank exceeds a predetermined amount, executes a first calculation process in which the available travel distance is calculated with reference to the remaining amount of the urea aqueous solution. The controller, after the remaining amount of the urea aqueous solution becomes smaller than or equal to a predetermined amount, executes a second calculation process in which the available travel distance is calculated by subtracting the period travel distance from the previously calculated available travel distance.

Such a mobile recycler that an operator can replenish a reducing agent tank with a reducing agent from the ground is provided. A reducing agent tank stores a reducing agent supplied to an exhaust gas treatment device treating an exhaust gas from an engine through reduction reaction. A tank case accommodates the reducing agent tank. The tank case has a support base supporting a container of the reducing agent for replenishment to the reducing agent tank.

An arrangement for testing or treating a dosing valve of a dosing device of a dosing system in a vehicle includes connecting an electrical test drive to an electrical connector of the dosing device and connecting a dosing tester to a liquid inlet of the dosing device. Thereafter, an outlet valve of the dosing tester is opened to provide liquid under pressure to a liquid inlet of the dosing device. After a first given time, the electrical test drive provides pulses to repeatedly attempt to open the dosing valve. Upon a reduction in liquid level of liquid within the dosing tester in response to opening of the dosing valve, an operator closes the outlet valve of the dosing tester to discontinue the treatment.

An apparatus includes at least one tank having a tank bottom and a delivery unit for a liquid. The delivery unit is disposed in a chamber on the tank bottom and the chamber has at least one heater.

A container is provided for a liquid operating medium of a motor vehicle. The container includes: i) an outer container which forms a container volume; ii) at least one heating device which is designed to thaw frozen operating medium, and iii) a partition which divides the container volume into a proximal region and a distal region. The proximal region is arranged closer to the at least one heating device than the distal region. The partition is designed to let through more operating medium between the proximal region and the distal region in the installation position of the container than in an oblique position of the container.

A pressure-releasing breather hose 1 mounted on a urea water tank 2 is dividably constituted by a flexible joint portion 1a with an end capable of being fitted over a hose joint 3 on the tank 2, and a vertical portion 1b connected to the other end of the joint portion 1a and suspending downward along a side surface of the tank 2. The joint and vertical portions 1a and 1b are constituted by a rubber hose made of ethylene propylene diene terpolymer (EPDM) and a polyethylene pipe (resin pipe) made of high density polyethylene (HDPE), respectively.

An aftertreatment system includes a first dosing module, a second dosing module, and a reductant tank assembly. The reductant tank assembly includes a reductant tank, a header coupled to the reductant tank, and a first splitting device that splits a first flow from the header into a first inlet flow and a second inlet flow. A first inlet line and a second inlet line direct the first inlet flow and the second inlet flow to the first dosing module and the second dosing module. A first outlet line and a second outlet line direct a first outlet flow and a second outlet flow from the first dosing module and the second dosing module to a second splitting device. The second splitting device merges the first outlet flow and the second outlet flow into a second flow and provides the second flow to the header.

Systems and apparatuses include a diesel exhaust fluid tank, a first temperature sensor positioned within the diesel exhaust fluid tank and structured to provide first temperature information indicative of a first temperature, and a second temperature sensor positioned within the diesel exhaust fluid tank and structured to provide second temperature information indicative of a second temperature. The systems and apparatuses further include one or more processing circuits including one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to provide energy to a heating system based on the first temperature information and the second temperature information.

To control elevation of the temperature of the reducing agent in a reducing agent tank which is located near a heat generating control valve in a construction machine, a tank storage room 8 housing a urea aqueous tank is located at the upper side of a valve housing room where control valves are housed. The urea aqueous tank is mounted at the upper side of a bulkhead plate which separates a tank storage room and the valve housing room one above the other having an empty space between so that air can flows through an air flow path S, and a space A is provided between a cover body covering the tank storage room and a cover body covering the valve housing room so that the air flows in and out through the space A and the air flow path S.
