摘要： A procedure is introduced to operate a diesel engine (10), which has a catalytic converter (24; 26) with three-way conversion characteristics. The procedure is characterized thereby, in that if the engine rotational speed (n) increases without in the process exceeding an engine rotational speed threshold value (n_S) and the engine's load (mk) is greater than a load threshold value (mk_S), the diesel engine (10) is operated in such a manner that the diesel engine (10) alternately generates an oxidizing and a reductive exhaust gas atmosphere before the catalytic converter (24; 26). Additionally a control unit (14) is introduced, which controls the sequence of the procedure.

摘要： The disclosure concerns a procedure for the regeneration of a particle filter and the desulfurization of a NOx storage catalytic converter in an exhaust gas aftertreatment system of an internal combustion engine. The disclosed procedure allows for the necessary heating energy and fuel consumption required to completely or partially regenerating the particle filter to be significantly reduced. Furthermore, an increase in efficiency of the NOx storage catalytic converter results, because the process reduces the average sulfur absorption on account of a greater frequency of desulfurization phases. In so doing, the NOx emissions after the NOx storage catalytic converter can further be reduced.

摘要： The invention relates to a method for regenerating an emission control system of an internal combustion engine, comprising a storage catalytic converter, a first exhaust gas probe being situated in an exhaust gas tract upstream of the storage catalytic converter and a second exhaust gas probe being situated in a second exhaust gas tract downstream of the storage catalytic converter. A first output signal of a first exhaust gas probe and a second output signal of a second exhaust gas probe are supplied to an engine management system and the storage catalytic converter is regenerated by being exposed to a reductant in a regeneration phase. If the quantity of reductant is controlled by the engine management system during the regeneration phase, whereby said system detects the quantity of reductant that is present downstream of the storage catalytic converter by means of the second output signal of the second exhaust gas probe situated downstream of said converter, the charging of reductant can be significantly reduced with respect to an optimised dosage. Excess consumption of fuel or reductant as a result of the regeneration of the storage catalytic converter is minimised. In addition, the method improves the emission values, thus significantly contributing to the maintenance of emission limits.

摘要： A procedure for metering a reagent into an exhaust duct of a combustion engine, which is required for a catalytic conversion of NOx in a SCR-catalyzer and a device for implementing the procedure are suggested. Determined is the difference between a calculated and a measured NOx-concentration each downstream after the SCR-catalyzer. The difference is compared to a difference threshold. After an exceeding of the difference threshold a lowering of the metering rate on to a sinking metering rate is undertaken, which is higher than zero. After a waiting time, a comparison of the calculated and the measured NOx-concentration is provided each downstream after the SCR-catalyzer. If the measured NOx-concentration is above the calculated NOx-concentration the metering rate is increased. If the measured NOx-concentration is below the calculated NOx-concentration the metering rate is lowered. The approach according to the invention enables an adaptation of the metering, at which it is ensured that a NOx-conversion can always take place.
