Abstract: The invention relates to a system (2) for storing a liquid additive to be injected into the exhaust gases of an internal combustion engine of a vehicle, comprising: an additive storage tank (4) comprising means for setting a maximum filling level of the tank, an additive retention capacity which fluidically communicates with the tank (4), said capacity being designed so as to retain the additive coming from the tank, wherein the additive retention capacity and the tank (4) are adjacent and have at least one common wall (8).

Abstract: A system for storing an ammonia precursor including a tank configured to hold the ammonia precursor; a filler opening closed by a cap, the cap being removable for refilling the tank; and a semi-permeable membrane positioned within the cap. The semi-permeable membrane is configured to block liquid from the ammonia precursor and configured to allow air and vapors from the ammonia precursor to pass therethrough when the cap is closing the filler opening. When the cap is closing the filler opening, a pathway allowing a substantial amount of vapors to escape from the tank to the atmosphere is provided so that the total internal volume of the reservoir in liters divided by the flow rate in liters per hour through the membrane at 10 mbar is lower than 20 hours.
