Abstract: A facility for treating exhaust gases from an internal combustion engine (1) comprises catalytic oxidation means (3), a particle filter (4) placed downstream from the catalytic oxidation means (3), a reformer (5) to produce reformate. The reformate is introduced with the exhaust gases upstream of the catalytic oxidation means in order to obtain a pre-set recommended temperature Tcons of the gases heated upstream of the particle filter (4), so as to regenerate the particle filter (4) by raising the temperature of the gases, a calculated reformate flow Qref_calc is determined as a function of the recommended temperature Tcons, a discrepancy coefficient is determined as a function of the difference between the recommended temperature Tcons and a measured temperature Tmes upstream of the particle filter, and the reformer (5) is controlled with a recommended reformate flow Qref_cons as a function of the discrepancy coefficient a and the calculated reformate flow Qref_calc.

Abstract: A method for desulfating an NOx trap of an exhaust line of a diesel engine, the method to extract during the operation of the engine at least one portion of the fixed sulphur compounds in the NOx trap. The method produces a reformate via a reformer device from the fuel of the engine, preheat the NOx trap via injection of the reformate in the flow of exhaust gases, in an injection point located downstream of the engine is upstream of the NOx trap, until a predetermined desulfation temperature is reached in the NOx trap, then bypasses the flow of exhaust gases from a bypass point of the exhaust line located upstream of the injection point, and continues the injection of reformate in the NOx trap to produce the desulfation, the richness of the mixture supplying the diesel engine not being affected in the method.
