The disclosure relates to a fuel supply device for supplying a fuel to an internal combustion engine comprising: a fuel store for storing a primary fuel; and at least two parallel fuel supply paths that are connected to the fuel store, on the one hand, and to the internal combustion engine, on the other hand, wherein the primary fuel can be supplied from the fuel store to the internal combustion engine by means of the first fuel supply path for the purpose of combustion, and the second fuel supply path has at least one reforming device that reforms the primary fuel supplied from the fuel tank into a secondary fuel, and to supply at least a portion of the produced secondary fuel to the internal combustion engine for the purpose of combustion.

A connection head for being arranged in an orifice of a fluid tank with a return cavity in the form of a radial duct is provided. The return cavity overcomes the problems of the formation of air bubbles in the tank and enhances the functioning of the sensor in the tank.

An industrial vehicle includes: an exhaust gas treatment device arranged in an engine room so as to be located above an engine, the exhaust gas treatment device including a pretreatment unit accommodating a diesel oxidation catalyst and extending in the forward/rearward direction, a selective catalytic reduction unit located adjacent to the pretreatment unit and extending in the forward/rearward direction, a connecting pipe including a mix portion, a first bent portion, and a second bent portion, the mix portion being located between the pretreatment unit and the selective catalytic reduction unit and extending in the forward/rearward direction, the first bent portion connecting the mix portion and an outlet of the pretreatment unit, the outlet being located close to a dividing wall, the second bent portion connecting the mix portion and an inlet of the selective catalytic reduction unit, the inlet being located far from the dividing wall, and a urea water injection device attached to the first bent portion of the connecting pipe so as to be located on an extended line of the mix portion and configured to inject urea water into an exhaust gas; a urea water tank arranged outside the engine room and storing the urea water; and a urea water pipe configured to guide the urea water from the urea water tank to the urea water injection device and penetrating the dividing wall.

A preassembled line for axial engagement with a mating coupling part. The preassembled line includes a line connector having of a connector body with a connecting portion to which a media line is connected and also includes a coupling portion with sealing means for sealing relative to the mating coupling part. The media line is provided with a heating wire arranged on the coupling portion. The connector body, the media line and the heating wire being surrounded at one end by a housing that has a latching part for connecting with the mating coupling part. The latching part is formed on the housing portion surrounding the coupling portion. Sealing of the preassembled media line to the mating coupling part is separated from connecting of the preassembled media line to the mating coupling part and separately performed by the connector body and the housing.

An exhaust treatment device includes a dosing and mixing assembly having a wire mesh puck. A retaining arrangement holds the mesh puck and maintains the mesh puck in an axially compressed state. The compressive force may be sufficient to inhibit rotation of the wire mesh. A peripheral side of the wire mesh is allowed to float while edges of the axial ends are trapped between at least two stop members of the retaining arrangement.

A reductant insertion system for an after treatment system configured to decompose constituents of an exhaust gas, includes: a dry reductant tank configured to contain a dry reductant; a reductant delivery line configured to operatively couple the dry reductant tank to the after treatment system for delivery of the dry reductant to the after treatment system; and a pressurized gas source configured to communicate the dry reductant to the after treatment system through the reductant delivery line using pressurized gas.

An operating material supply system for a motor vehicle includes: i) at least one operating material container for storing operating material at risk of freezing; ii) at least one conveying device, which is designed to convey the operating material stored in the operating material container upstream in the direction of at least one injector, or in the opposite direction downstream, iii) at least one air separator, which is connected to the operating material container via a feed line; iv) at least one first injector line, which connects the air separator to at least one first injector. When the air separator is installed in the motor vehicle, a connector for the first injector line is distanced further from the roadway surface than a connector for the feed line.

A method and a device for determining the injection quantity or the injection rate of a fluid which is transported to an injector through a hydraulic line and is injected into a reaction space by the injector. The fluid pressure in the hydraulic line is measured by a pressure sensor, the fluid pressure at the injector is determined using the pressure measured by the pressure sensor and a stored transmission function of the hydraulic line, and the injection quantity or the injection rate of the fluid injected by the injector is determined using the fluid pressure determined at the injector.

In a urea injection system of a vehicle, to detect the shortage of the cooling water by using an electric water pump (EWP) to cool a dosing injector during the running of the vehicle engine, the apparatus for detecting shortage of the cooling water in the vehicle includes a urea injector that injects urea into an exhaust pipe of the vehicle, a pump that cools the urea injector, and a controller that applies a reference current to the pump, measures a time taken until a revolutions per minute (RPM) of the pump reaches a reference RPM, and detects the shortage of the cooling water in the pump by comparing the measured time and a reference time.

Tank for a liquid solution based on water and urea which is suitable for being combined with a selective catalytic reduction system. The tank comprises: a container including an upper wall; a filling pipe union which is positioned on the upper wall of the container and which is suitable for introducing the liquid solution; a lower opening, from which the liquid solution being introduced passes into the container and which protrudes with respect to the upper wall towards the interior of the container; a closure float which is positioned in the container and which is connected to the lower opening and which is configured so as to raise and close the lower opening once the liquid solution in the container reaches a predetermined level.
