Abstract

Procédé pour le stockage et l'injection d'un additif dans des gaz d'échappement d'un moteur et comprenant deux réservoirs pour le stockage de la solution et une pompe d'alimentation de la solution de ces réservoirs vers une ligne d'injection, ces deux réservoirs étant en parallèle et reliés à la pompe chacun par une branche de ligne d'alimentation, chacune de ces branches étant munie d'un clapet anti-retour et ces deux clapets étant tarés de manière à ce que le clapet situé dans la branche issue du premier réservoir (1) soit normalement ouvert mais se ferme lorsque ce réservoir est vide, et à ce que le clapet situé dans la branche issue de l'autre réservoir (2) soit normalement fermé mais s'ouvre lorsque le clapet du réservoir (1) est fermé ou que la branche issue de ce réservoir (1) est obstruée.Process for the storage and injection of an additive in the exhaust gases of an engine and comprising two tanks for the storage of the solution and a pump for feeding the solution from these tanks to an injection line , these two reservoirs being in parallel and each connected to the pump by a branch of the supply line, each of these branches being provided with a non-return valve and these two valves being calibrated so that the valve located in the branch from the first tank (1) is normally open but closes when this tank is empty, and the valve located in the branch from the other tank (2) is normally closed but opens when the valve of the reservoir (1) is closed or that the branch issuing from this reservoir (1) is blocked.
