An exhaust after-treatment system associated with a diesel engine includes a diesel exhaust fluid storage unit. The storage unit includes a diesel exhaust fluid tank and a vent system coupled to the tank and configured to regulate flow of air into the tank and fluid vapor out of the tank.

The application relates to a pouch assembly (100) containing a liquid being an aqueous urea solution for use in a selective catalytic reduction system for treating the exhaust gases of an internal combustion engine of a vehicle and for transferring the liquid to a liquid tank of the vehicle from the outside of the liquid tank, the pouch assembly (100) comprising a flexible pouch (1) and a spout (2) attached thereto having a base (21) extending axially through an opening (111) provided in a wall of the pouch (1) and being attached to the opening (111), a top end (22) being configured for insertion in the inside passage of the filling neck (3) of the liquid tank during the filling of the liquid tank, and a body (23) that extends between the base (21) and the top end (22) of the spout (2), the body (23) having an elongated shape, and the body (23) at least partially extending in the inside passage of the filling neck (3) of the liquid tank during the filling of the liquid tank, the base (21), the top end (22) and the body (23) having an elongated axial through-passage (211) to serve as a discharge passage for the liquid. The application relates furthermore to a system comprising such a pouch assembly (100) and a liquid tank having a filling neck (3) allowing insertion of the spout (2) for filling the liquid tank.

An automated diesel exhaust fluid (DEF) system and method for refilling DEF. The automated DEF system provides DEF refilling after an initial setup and without manual intervention. The automated DEF system includes a electric DEF flow control device that controls the flow of DEF. The electric DEF flow control device may include control circuitry, an electrics enclosure that encloses the control circuity, an electric fluid sensor, a valve, a beacon light, a status light, a button, a threaded swivel connection, and a mandrel on the inside of the threaded swivel connection.

The invention relates to a filler head (23) for a storage system comprising a body with a main part (31) closed by a cover part, and being configured to receive a distribution nozzle of a fluid and configured to be connected, in a tighten manner, to a filling line and a venting line of a fluid tank, the filler head (23) further comprising a buffer volume (33) so as to reduce the speed of flow (V) coming from the venting line (21), the buffer volume (33) being in one-piece with the main part (31) and is closed by the cover part so as to limit fluid projection from the filler head (23) during refilling.

Systems are provided for an assembly for a urea tank system. In one example, coaxial tubes including an inner tube and an outer tube are used to separate a urea passage from a gas passage. An angled tube, which extends from a urea tank to a portion of the outer tube downstream of a filler head relative to a direction of urea flow directs gases from the urea tank to the gas passage. This decreases a packaging size of the urea tank system.

The present disclosure relates to a device for preventing overflow of urea water out of an injection hole of a urea water tank when urea water is injected into the injection hole. The device is configured to enhance the function of a ventilation flow path, thus efficiently relieving pressure in the urea water tank when urea water is injected into the urea water tank.

An opening device for a urea water inlet may include a first body configured to be provided on an external side of an inlet of a urea filler neck; a second body disposed at an upper end portion of the first body with a ventilation gap between the first body and the second body, and provided with an internal space to be disposed above the inlet; a cover disposed at an upper end portion of the second body, and configured to receive a force to open the internal space of the second body; an opener provided in the second body, and configured to hold the cover at the upper portion of the second body when the cover is configured to close the internal space, and to release holding of the cover when being pressed toward an interior of the second body; and a membrane disposed between the first body and the second body to pass only air therethrough while covering the ventilation gap.

A fluid container includes a tank, a magnetic ring, and an adaptor coupled to the tank via an o-ring seal. The magnetic ring includes two half-ring portions that, when assembled, form a full magnetic ring. The fluid container can be used to store DEF or other fluids. Assembling the fluid container includes positioning the magnetic ring within a groove formed in an outer surface of a conduit of the tank, and threading the adaptor onto the conduit to lock the magnetic ring in place.

The application relates to a pouch assembly (100) containing a liquid being an aqueous urea solution for use in a selective catalytic reduction system for treating the exhaust gases of an internal combustion engine of a vehicle and for transferring the liquid to a liquid tank of the vehicle from the outside of the liquid tank, the pouch assembly (100) comprising a flexible pouch (1) and a spout (2) attached thereto having a base (21) extending axially through an opening (111) provided in a wall of the pouch (1) and being attached to the opening (111), a top end (22) being configured for insertion in the inside passage of the filling neck (3) of the liquid tank during the filling of the liquid tank, and a body (23) that extends between the base (21) and the top end (22) of the spout (2), the body (23) having an elongated shape, and the body (23) at least partially extending in the inside passage of the filling neck (3) of the liquid tank during the filling of the liquid tank, the base (21), the top end (22) and the body (23) having an elongated axial through-passage (211) to serve as a discharge passage for the liquid. The application relates furthermore to a system comprising such a pouch assembly (100) and a liquid tank having a filling neck (3) allowing insertion of the spout (2) for filling the liquid tank.
