METHOD AND DEVICE FOR SELECTIVE CATALYTIC REDUCTION OF STICKOXYDE FROM COMBUSTION ENGINE EXHAUST GAS |
| abstract |
In a process for the selective catalytic reduction of the nitrogen oxides from exhaust gases of internal combustion engines, wherein the reduction reaction takes place in a reactor (21) after an addition of ammonia, an ammonia addition which is as exact as possible is accomplished as a function of the actual value of the nitrogen oxide concentration in the combustion exhaust gas in such a way that the ammonia addition takes place as a function of the nitrogen oxide concentration in the exhaust gas and the nitrogen oxide concentration is determined indirectly by measuring running parameters of the internal combustion engine (14) and subsequent calculation taking into account characteristic line fields of the nitrogen oxide concentration as a function of selected running parameters on the internal combustion engine (14). A device for carrying out this process has a data-processing unit (11) with characteristic line field memories (12, 13) for storing pairs of values which associate the nitrogen oxide concentration values with load-dependent air numbers of the internal combustion engine. Such a data processing unit is equipped with a data input unit (15, 15', 18) for measured values of actual air numbers and actual load conditions of the internal combustion engine and with a data output unit for the quantities of ammonia to be fed to the exhaust gas of the internal combustion engine. The quantities of ammonia are calculated on the basis of the volumetric exhaust gas flow and of the air number with the aid of the characteristic line fields in accordance with empirical reaction equations. <IMAGE> |
