Abstract: A method for filling a reservoir on board a motor vehicle by a reserve cartridge. The reservoir includes a filler pipe, including a device for sealed attachment of the cartridge to the pipe. The cartridge includes a latching device configured to allow the fluid to flow from the reserve cartridge into the reservoir filler pipe only when the cartridge is attached in a sealed manner to the device on the pipe. The reserve cartridge is attached in a sealed manner to the pipe attachment device and the reserve cartridge latching device is unlatched so that the fluid can flow from the reserve cartridge into the filler pipe.

Abstract: Additive reservoir for a fuel system, comprising a closed plastic enclosure associated with a main fuel tank filling tube. Two-step process for manufacturing such a reservoir, in which firstly a closed plastic enclosure is faintly and then the enclosure is assembled or connected onto a main fuel tank filling tube.

Abstract: An additive tank for a vehicle having an internal combustion engine, the tank including a flexible bag which contains the additive and is connected to a device allowing the flexible bag to be pressurized in order to meter the additive.

Abstract: A device for assembling a shield containing at least one hole onto a tank, a shield intended for such a device, an assembly method using the device, and a tank including the device. The device includes a base configured to be firmly attached to a wall of the tank, and a head used for fixing the shield, the head including a groove whose lower and upper lateral surfaces intersect an axis of the device substantially normal to the wall of the tank, the groove being used such that the edge of the hole in the shield slides into the groove. The device also includes a non-return stub that emerges from the outer surface of the device and prevents detachment of the shield from the tank.

Abstract: A fuel system, and a method for manufacturing such a fuel system, for an internal combustion engine operating with a liquid fuel and including a fuel reservoir intended for the fuel and an additive reservoir including a chamber formed in a concave recess of the wall of the fuel reservoir.
