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 thermally decomposing a ammonia precursor in a heater (3) mounted on board the vehicle; - directing the refilling ammonia gas to the solid absorbing matrix where it is stored thereon.

摘要:
It is proposed a method for assembling a tank, comprising: - providing a plastic first shell, a plastic second shell with an opening, and at least one connecting member with a plastic end part suitable for being arranged in or around said opening, said first and second shell delimiting an internal volume of the tank, and said connecting member being dimensioned for connecting said first and second shell in the internal volume of the tank; - welding a circumference of said first shell to a circumference of said second shell; - arranging said end part in or around said opening; and - connecting said end part of said connecting member to a wall part of said second shell by heating an external area of the second shell surrounding said opening and/or by heating said end part of said connecting member.
