computer program for controlling the emission of nitrogen oxides

摘要

computer program, a computer code comprehensively, which is appropriate for a procedure for the control of emissions of nitrogen oxides in a combustion engine (110) to the combustion engine and has a nachbehandlungssystem, comprising: a particulate filter (284), the egg a first selective catalytic reduktionssystem (284) (here referred to is scrf)and a second selective catalytic reduktionssystem (285) downstream from the scrf, involving the following steps are executed:- injection urea water solution to the oxides of nitrogen by means of the second selective catalytic reduktionssystems (285) to reduce, if partikelfilterregeneration is active- resume the injections a urea water solution, if not deaktivierungsbedingungen are met.
