摘要:
SCR method for_purifying the exhaust gases of an internal combustion engine of a vehicle, according to which ammonia gas is exclusively metered in the exhaust gases, the method comprising a step of releasing ammonia gas from at least one solid absorbing matrix where it is stored by sorption and a step of metering the released ammonia gas in the exhaust gases. The method is such that it comprises a step of regenerating the solid absorbing matrix that consists in: - generating a refilling ammonia gas by chemically decomposing a ammonia precursor in a biochemical decomposition unit (3) mounted on board the vehicle and storing at least one protein component adapted to decompose said ammonia precursor; - directing the refilling ammonia gas to the solid absorbing matrix where it is stored thereon.
摘要:
The invention proposes a method for diagnosing a system for storing a gas, the gas being stored by sorption on a compound, the system being mounted onboard a vehicle and comprising a tank capable of containing the compound and a control device capable of controlling a heating device in order to increase the temperature of the compound in such a way as to release the gas. The control device is such that it obtains (E21) a set of information comprising at least one measurement of the temperature of the system, then carries out an estimation (E22) of the gas pressure in the system by using a predetermined kinetic model of desorption of the gas.

Device for pumping a liquid comprising: - a rigid core tube (11); - a flexible tube (10) positioned outside and at least partly around said rigid core tube (11); - a passage for the liquid from an inlet towards an outlet of the device and comprising a free volume (13) extending between the rigid core (11) and the flexible tube (10); and - a squeezing arrangement (12) comprising at least one pressing element (40,70,80) capable of acting on the flexible tube so as to alter the shape and/or size of the free volume (13). Liquid injection system comprising such a device.
摘要:
A plastic fuel tank comprising an upper wall, a lower wall and at least two compartments, said compartments being established by a dividing wall comprising a part of the tank upper and lower walls, said dividing wall having at least one communication means enabling free flow of liquids between at least two compartments and at least one communication means enabling free flow of vapors between at least two compartments, and formed by welding together a multiplicity of contact points of the upper and lower walls.
摘要:
Process for reinforcing a plastic fuel tank comprising a wall defining an internal closed volume, according to which a structural member is fixed to the wall of the tank outside the closed volume, in at least two points being located in two different portions of said wall where a deflection induced when the tank is filled with fuel, is low; and said structure having at least one contact point with the tank wall in a portion of said wall where the deflection is high.
摘要:
Provided is a tank (1) for storing a gas, the gas being stored by sorption to a compound. The tank includes a receptacle (2) capable of containing the compound. The receptacle is such that it includes shock-absorbing means (3).
摘要:
A tank for storing an internal combustion engine exhaust gas liquid additive, the tank including a wall defining an internal volume, an electrical component located in the internal volume, and at least one electric cable configured to connect the electrical component to a voltage source outside the tank, at least one portion of the electric cable being inserted into an intermediate part connected to a base plate mounted over an opening in the wall, the base plate incorporating a casing mounted leaktight around an orifice in the base plate. The intermediate part is fastened by a quick-connect coupling including an electrical connector to which the electric cable is connected leaktight with aid of a seal and that emerges from the orifice in the base plate to outside the tank. The seal is inserted between the intermediate part and the connector and/or into a housing of the intermediate part.
摘要:
The invention concerns a method for making a fuel tank in plastic material from two shells formed by moulding, which are assembled, the moulding of at least one shell being carried out by compressing part of a plastic sheet (1) between a mould and a punch (5a) and by blowing the remaining part of the sheet, in the non-compressed zone.
