Kind Code:
B2
Abstract:
Exhaust after-treatment system of an internal combustion engine, namely SCR exhaust aftertreatment system, with an SCR catalyst (9), with an SCR catalyst (9) leading exhaust gas supply line (8) and with a SCR from the catalyst (9) leading away exhaust gas discharge line (11), with a the exhaust gas inlet (8) associated introduction device for introducing a reducing agent, in particular ammonia or an ammonia precursor substance, in the exhaust gas, and with a from the exhaust gas supply line (8) downstream of the introduction device provided mixing section for mixing the exhaust gas with the reducing agent upstream of the SCR Catalyst (9), wherein the exhaust gas feed line (8) with a downstream end (15) in a SCR catalyst (9) receiving the reactor chamber (10) opens, and wherein within the reactor space (10) between the downstream end (15) of the Exhaust gas supply line (8) and the SCR catalytic converter (9) have an apparatus (25) for increasing an exhaust gas back pressure upstream of the SCR system. Catalyst (9) is positioned.
