METHOD AND DEVICE FOR CATALYTICALLY REDUCING EMISSION CONCENTRATIONS IN THE EXHAUST GAS OF A COMBUSTION SYSTEM

摘要

A problem encountered in computer-controlled diesel catalytic converters is the slowing down of reactant activity. The invention thus provides for the dosage (S10) of the reactant (10) to be coupled (S2, S8) by means of a functional relationship to operation-relevant parameters of the combustion system, for said functional relationship to be corrected (S4, S5, S7) by autoadjustment via emission measurements and for the reactant (10) to be dosed rich of stoichiometry in relation to the calculated emission concentration of the exhaust gas (6). This prevents a slowing down of reactant activity.
