Abstract

An exhaust gas aftertreatment system (3) of an internal combustion engine, namely SCR exhaust gas aftertreatment system, with an SCR catalytic converter (9) received in a reactor chamber (10), with an exhaust gas feed line (8) leading to the reactor chamber (10) and thus to the SCR catalytic converter (9), with an exhaust gas discharge line (11) leading away from the reactor chamber (10) and thus from the SCR catalytic converter (9), with an introduction device (16) assigned to the exhaust gas feed line (8) for introducing a reducing agent, in particular ammonia or an ammonia precursor substance into the exhaust gas, and with a mixing section (18) provided by the exhaust gas feed line (8) downstream of the introduction device (16) for mixing the exhaust gas with the reducing agent upstream of the reactor chamber (10) or SCR catalytic converter (9). The exhaust gas aftertreatment system (3) comprises multiple blowing devices (24) which serve for blowing clear the SCR catalytic converter (9). Furthermore, the exhaust gas aftertreatment system (3) comprises a pressure accumulator (25) that is common for the blowing devices (24), which extends circularly or polygonally about the SCR catalytic converter (9) and about the blowing devices (24), wherein the blowing devices (24) originating from the common pressure accumulator (25) can be supplied with a medium for blowing clear the SCR catalytic converter (9).
