    摘要： The invention further relates to a method and a model for modeling a discharge phase of a nitrogen oxide (NOx)-storage catalytic converter (12′) of an internal combustion engine (1). The NOx-storage catalytic converter (12′) is subdivision into an oxygen (O2)-store and a nitrogen oxide (NOx)-store and a reducing agent mass flow (msrg) is determined which charges the O2-store and the NOx-store. To model a discharge phase of the NOx-storage catalytic converter (12′), the O2-store is modeled via a first integrator for oxygen (O2) and the NOx-store via a second integrator for nitrogen oxide (NOx) and the first integrator and the second integrator are charge proportionally with the reducing agent mass flow (msrg) in accordance with an apportioning factor determined in dependence upon the O2-store content (mo2sp) and the NOx-store content (mnosp) of the NOx-storage catalytic converter (12′).

    摘要： A method of desulfurization of a ceramic storage medium for sulfur oxides and/or nitrogen oxides situated in a gas stream, in particular a storage device for nitrogen oxides or sulfur oxides situated in the exhaust gas stream of an internal combustion engine, is described, a mixture having a low oxygen concentration being established in the gas stream to release the stored sulfur oxides. A measuring signal is recorded by an oxygen probe positioned downstream from the storage medium in a gas stream flow direction, the curve of this measuring signal being used to determine the loading of the storage medium with sulfur oxides. This method allows determination of the need for desulfurization as a function of the loading of the storage medium with sulfur oxides, to monitor and control the progress of desulfurization initiated and to check on how complete the desulfurization that is concluded has been.

    摘要： An internal combustion engine is operated with direct fuel injection into the combustion chambers. Furthermore, the internal combustion engine is operated with sub-optimum ignition angle efficiency and an apportionment of a fuel quantity, which is to be injected before the start of a combustion, into at least two partial injections. A torque loss which results from the sub-optimum ignition angle efficiency and/or from the apportionment of the fuel to be injected is compensated by means of an increased charge of the combustion chambers. The fuel quantity and the charge are coordinated with one another in such a way that the air ratio lambda of the combustion chamber charges is greater than 1. The method is characterized in that a measure for a temperature of the catalytic converter, in particular a measure for the temperature at the inlet of the catalytic converter, is determined and in that a quantity of reducing exhaust-gas constituents is increased by means of at least one intervention into the control of the internal combustion engine if the measure for the temperature exceeds a predetermined temperature threshold value. The approach according to the invention permits rapid heating of the catalytic converter, wherein the hydrocarbon emissions when the catalytic converter is cold are at the same time as low as possible.
