Abstract (en)
[origin: WO2016042224A1] Method for treatment of the exhaust gases of an internal combustion (1), comprising: a step of absorbing NOx in the LNT (5), - a step of ammonia production in the LNT (5), a step of supplying the SCR (6) with ammonia produced in the LNT (5), according to the needs estimated by the computer, a step of reduction of the NOx in the SCR (6) by chemical reaction of the NOx with the injected ammonia, the process comprising an additional step of ammonia injection into the SCR (6) when the quantity of ammonia produced in the LNT (5) is deemed insufficient, the ammonia thus injected being pushed into an auxiliary storage container (9) containing a reducing agent comprising ammonia.
