摘要:
The invention relates to an exhaust gas aftertreatment system (3) with an exhaust gas inlet (9), at least two exhaust gas aftertreatment elements (11, 13), and a flow chamber (15). According to the invention, - the exhaust gas inlet (9), the at least two exhaust gas aftertreatment elements (11, 13), and the flow chamber (15) are arranged relative to one another and fluidically connected together such that exhaust gas flowing through the exhaust gas inlet (9) into the flow chamber (15) can be distributed to the at least two exhaust gas aftertreatment elements (11, 13). The exhaust gas passes through at least one first of the at least two exhaust gas aftertreatment elements (11, 13) along a first flow direction, and the exhaust gas passes through at least one second of the at least two exhaust gas aftertreatment elements (11, 13) along a second flow direction, wherein the first flow direction and the second flow direction are oriented at least diagonally to each other, preferably anti-parallel to each other.
摘要:
The invention relates to a method for determining the aging of an oxidation catalyst (7) in an exhaust gas aftertreatment system (3) of an internal combustion engine (1), having the following steps: ascertaining a soot burn rate (31) of a particle filter (7) of the exhaust gas aftertreatment system (3); adapting a function comprising at least one adaptation parameter (39) to the soot burn rate (31) dependent on at least one variable, a value of the adaptation parameter (39) depending on an aging of the oxidation catalyst (7); and determining the aging of the oxidation catalyst (7) using the adaptation parameter (39) value ascertained by adapting the function.
摘要:
A method for execution with an exhaust-gas particle filter (9) which is operated with an exhaust-gas aftertreatment system (5), wherein the exhaust-gas particle filter (9) has a filter wall (13) along which exhaust gas is conducted for filtering purposes; wherein the method comprises a regeneration phase with the steps: a) setting a soot load on the exhaust-gas particle filter (9), wherein the set soot load effects the formation of a soot layer on ash deposited on the filter wall (13); and b) subsequently mobilising the deposited ash by burning off the formed soot layer during the course of an active regeneration of the exhaust-gas particle filter (9).
