It is proposed a plastic liner for the storage of hydrogen, comprising: a first barrier layer (), a second barrier layer () configured to be an inner layer in contact with hydrogen, at least one intermediate layer arranged between the first and the second barrier layers, wherein the second barrier layer () has a lower hydrogen permeability than said at least intermediate layer such that the second barrier layer () slows down the migration of hydrogen inside said at least one intermediate layer.

Plastic liner for a composite pressure vessel

The invention relates to a pressure vessel system comprising a pressure vessel for storing a gas under pressure, at a potential leakage interface of the pressure vessel, one or more gas sensitive parts configured to undergo a modification when the gas passes along the potential leakage interface; said leakage interface being an interface within the pressure vessel; and one or more detection modules configured to detect a modification of the one or more gas sensitive parts. The invention also relates to a connection assembly comprising a first connection part and a second connection part, said first and second connection part being configured to realize a gas tight connection; one or more gas sensitive parts arranged at a connection interface between the first connection part and the second connection part, and one or more detection modules configured to detect a modification of the one or more gas sensitive parts.

A method is provided for loading or reloading a decomposition unit of an SCR system, the SCR system being mounted on board a vehicle and including a filler pipe in communication with the decomposition unit. The method is such that at least one capsule containing at least one protein component adapted to decompose ammonia precursor is introduced through the filler pipe and is then guided through the filler pipe towards the decomposition unit.

Method and system for purifying the exhaust gases of a combustion engine

A method for managing operation of a component of a system for storing and injecting an additive into exhaust gases of a combustion engine. The system includes a container for storing the additive and the method includes: obtaining an instantaneous measurement of concentration of additive and/or an instantaneous measurement of alkalinity of the additive and/or an instantaneous measurement of the temperature inside the container, by one or a plurality of measurement sensors mounted inside the container; determining reducing power of the additive based on the instantaneous measurement of concentration of additive and/or an instantaneous measurement of the alkalinity of the additive and/or temperature inside the container; generating a control signal, based on the defined reducing power; transmitting the generated control signal to the component.

A method for loading or reloading a decomposition unit of a vehicular system, the vehicular system including a filler pipe in communication with the decomposition unit. The method includes introducing at least one capsule including at least one protein component adapted to decompose ammonia precursor through the filler pipe and which is then guided through the filler pipe towards the decomposition unit.

Method and system for loading or reloading a decomposition unit for use in a vehicle

An 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 thermally decomposing an ammonia precursor in a heater mounted on board the vehicle; directing the refilling ammonia gas to the solid absorbing matrix where it is stored thereon.

Method for heating a urea SCR system using at least two resistive heating elements (R, R), one of which (R) is intended for heating one or some (part(s) of) component(s) always in contact with a substantial amount of urea and the other (R) is intended for heating one or some (part(s) of) component(s) which are sometimes not in contact with a substantial amount of urea, and according to which, when starting the system in freezing conditions, the resistive element Ris activated but the resistive element Ris activated only when its component is actually in contact with a substantial amount of urea.

Method for heating an SCR system using resistive heating elements

System for storing an additive solution and injecting it into the exhaust gases of an engine, said system comprising two tanks for storing the solution and one pump for supplying the solution from these tanks to an injection line, these two tanks being in parallel and each being connected to the pump by a branch of a supply line, a first branch coming from the first tank giving rise to lower pressure drops than a second branch coming from the second tank so that the solution is normally withdrawn mainly from the first tank and is withdrawn from the second tank, and is only withdrawn from the second tank when the first tank is non-operational.

System for closing off an opening in a plastic tank, formed from a sheet of multilayer plastic that includes a barrier layer, the said sheet being welded around the perimeter of the opening and provided with a peripheral region that is slimmed down so as to effectively restrict the permeation of gases and liquids into the layer located between the tank and the barrier layer. Method of closing of a tank by welding such a plate, comprising the welding of the slimmed-down peripheral part by the technique of laser or infrared radiation welding. Use of the method to close off a fuel tank for a motor vehicle.
