| titleOfInvention | Method and device for purifying an exhaust gas stream of an exhaust-charged internal combustion engine |
| abstract | The invention relates to a method for purifying an exhaust gas stream of an exhaust-gas-charged internal combustion engine in which nitrogen oxides are removed from the exhaust gas stream by means of selective catalytic reduction (SCR), wherein the exhaust gas stream (6) upstream of an exhaust gas turbine of an exhaust gas turbocharger and upstream of at least one SCR catalyst (12 ) into a main exhaust gas stream (6 ') guided in a main exhaust gas line to the exhaust gas turbine (3') and into at least one bypass exhaust gas flow (6 '') guided in a bypass line and bypassing the exhaust gas turbine, preferably from the main exhaust gas stream. Is exhausted, split or is branched off, wherein the bypass exhaust gas stream (6 '') in defined engine operating conditions, a defined amount of a reducing agent precursor substance to be decomposed (11) is supplied in a reactor (9) of the bypass exhaust gas stream (6 ") is converted to a reducing agent, preferably to ammonia, which is exhausted by means of the bypass roms (6 '') discharged from the reactor (9) and upstream of the SCR catalyst (12) is supplied to the main exhaust gas stream (6 '), and wherein at least one coupled by means of a control and / or regulating device and in dependence on defined Operating parameters controllable shut-off and / or throttle device (7, 8; 21; 25; 27) is provided. According to the invention, at least one branch line is branched off from the main exhaust gas line downstream of the exhaust gas turbine (3, 3 '), which is upstream of the reactor (9). |
