Title: (EN) METHOD FOR OPERATING COMPONENT'S OF THE EXHAUST AFTERTREATMENT AND ALSO EXHAUST AFTER TREATMENT DEVICE
Abstract:
(EN) The invention relates to a method for operating components for exhaust gas after-treatment, which are arranged in the exhaust gas tract of a turbocharged internal combustion engine, wherein a partial exhaust gas stream (11) is removed from the main exhaust gas stream (10) upstream of at least one exhaust gas turbine (14). The partial exhaust gas stream (11) is fed back into the main exhaust gas stream (10) downstream of the at least one exhaust gas turbine (14), wherein at least one exhaust gas after-treatment component (6) is arranged downstream of said feed (7). According to the invention, the quantity of exhaust gas branched off as a partial exhaust gas stream (11) is controlled or regulated as a function of at least one target temperature in at least one defined point in the exhaust gas tract, in particular in the partial exhaust gas stream (11) and/or on the at least one exhaust gas after-treatment component (6).
