An exhaust gas aftertreatment system with an exhaust gas inlet, at least two exhaust gas aftertreatment elements, and a flow chamber. The exhaust gas inlet, the at least two exhaust gas aftertreatment elements, and the flow chamber are arranged relative to one another and fluidically connected together such that exhaust gas flowing through the exhaust gas inlet into the flow chamber can be distributed to the at least two exhaust gas aftertreatment elements. The exhaust gas passes through at least one first of the at least two exhaust gas aftertreatment elements along a first flow direction, and the exhaust gas passes through at least one second of the at least two exhaust gas aftertreatment elements 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.

Exhaust gas aftertreatment system, and internal combustion engine with exhaust gas aftertreatment system

Reciprocating-piston internal combustion engines having different power outputs are to be equipped simply, reliably and inexpensively with a device for the selective catalytic reduction of the exhaust gases having an SCR module for a reciprocating-piston internal combustion engine, comprising a housing and/or a frame, an exhaust-gas section which delimits a flow duct for guiding through exhaust gas, having an inlet opening for introducing the exhaust gas and an outlet opening for discharging the exhaust gas, an SCR catalytic converter which is arranged inside the flow duct, at least one injection element for adding a reducing agent, for example ammonia or a urea solution, to the exhaust gas which is guided through the flow duct. This problem is solved by virtue of the fact that the SCR module comprises at least one delivery device () for feeding the reducing agent to the injection element at a predetermined pressure.
