Abstract
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giving rise to lower pressure drops than a second branch coming from the second tank so that the solution is normally withdrawn mainly from the first tank and is withdrawn from the second tank, and is only withdrawn from the second tank when the first tank is non-operational.
