The filter assembly extends through the opening and is configured to seal the opening and includes a filtering material. The header assembly extends through the opening and inside the filter assembly. The header assembly includes: (i) a first sensor configured to measure a quality of the reductant contained within the filter assembly and (ii) a second sensor configured to measure a level of the reductant contained within the filter assembly.

Disclosed is a device for storing a liquid for a motor vehicle, the device including a reservoir, including a bottom wall, a pump, mounted at an orifice formed at the bottom wall and including at least one portion extending through the orifice and including at least one suction nozzle, a filter mounted on the at least one portion of the pump at the at least one suction nozzle, and a mat arranged inside the reservoir at least partly on the bottom wall, the mat being able to move the liquid by capillarity and including a so-called “contact” portion being in contact with the filter at a contact surface in order to convey the liquid by capillarity to the filter.

A header assembly for an aftertreatment system includes: a header including: a suction port, and a return port; a first splitting device configured to receive a first flow of reductant from the suction port and to split the first flow into a first inlet flow and a second inlet flow; a second splitting device configured to receive a first outlet flow and a second outlet flow and to provide a second flow to the return port of the header; a first inlet line configured to direct the first inlet flow to a first dosing module; a second inlet line configured to direct the second outlet flow to a second dosing module; a first outlet line configured to direct the first outlet flow to the second splitting device; and a second outlet line configured to direct the second outlet flow to the second splitting device.

An SCR dosing pump assembly for conveying and providing a liquid exhaust gas purification additive includes: a plastic housing; a multi-part aluminum frame having first part and a second part; and at least one positive temperature coefficient (PTC) heating element configured as an electrically conductive contact between the first part and the second part of the aluminum frame. No further electrically conductive contacts exist between the first part and the second part of the aluminum frame. The multi-part aluminum frame is molded into the plastic housing of the SCR dosing pump assembly.

A tank system includes an extraction device and a tank. The extraction device has an extraction line and an attachment device. The tank includes a tank top side having a fastening wall and a first tank top side section. The fastening wall and the first tank top side section delimit a tank interior space at the top side. The tank interior space can be filled with an exhaust-gas after-treatment liquid, the fastening wall is disposed obliquely to the first tank top side section, the fastening wall has a fastening surface and a tank opening, the attachment device is fastened to the fastening surface, and the extraction line is guided through the tank opening. A vehicle having the tank system is also provided.

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.

An exhaust aftertreatment system for increasing fractional efficiency of diesel or gasoline particulate filters includes a particulate filter that includes a housing and a filter substrate positioned in the housing. The filter substrate is pre-conditioned with an aqueous solution or suspension configured to decompose or evaporate in response to exposure to heat so as to precondition the filter substrate.

An aftertreatment system includes an exhaust reductant tank configured to store an exhaust reductant. A filter is fluidically coupled to the exhaust reductant tank. The aftertreatment system includes a hydrocarbon detection device configured to indicate the presence of a hydrocarbon in the exhaust reductant. A catalyst is included in the system and configured to treat the exhaust reductant flowing through the system. The hydrocarbon detection device can include a hydrophobic paper, and can be disposed in the filter.

Disclosed is a process for the dynamic monitoring of the flow rate of liquid additive consumed by a liquid-additive injector of an exhaust gas treatment system of a motor vehicle. The measurement of the pressure of the liquid makes it possible firstly to deduce the flow rate circulating through the orifice and secondly, by knowing the operating characteristic of the pump, to determine the flow rate of liquid additive actually delivered to the system for treating polluting gases. The process also provides a phase of characterizing the pump, including commanding the closure of the injector, measuring at least two pressure values for two different operating speeds of the pump, and updating the pump operating characteristics table on the basis of the pressure values measured.
