Benefits of technology
The patent text describes an improved exhaust gas purification system for internal combustion engines, particularly diesel engines. The system includes a primary exhaust gas treatment system, two catalysts, and an inlet line. The system is designed to increase the efficiency of nitrogen oxide conversion and reduce soot combustion. The technical effect of the patent is to provide a more effective and efficient system for purifying exhaust gases from internal combustion engines.
Problems solved by technology
However, because of this, some of the exhaust gases are not purified at all.
The disadvantage, however, because of the high thermal mass of the (diesel) particle filter, is that the temperature in the catalyst element rises very slowly, thus leading to reduced nitrogen oxide conversion of the catalyst.

[0027]FIG. 1 shows a diagrammatic set-up of an exhaust gas purification system 1 according to the invention for exhaust gases from an internal combustion engine, in particular from a diesel engine, said system being arranged in an exhaust tract 2. The exhaust tract 2 has an inlet line 3 and an outlet line 4. The exhaust gas purification system 1 according to the invention has two exhaust gas treatment elements which are designed as catalysts 6, 7.
[0028]Both catalysts 6, 7 have in each case an entry side 8 and an exit side 9 lying opposite this.
[0029]The inlet line 3 conducts exhaust gases coming from the internal combustion engine in the direction of the exhaust gas purification system 1 (arrow 11). On the inlet side, the inlet line 3 has a branch 12 which divides the inlet line 3 into two catalyst lines 13. Arranged in the branch 12 is a control valve 14. The control valve 14 is controlled by a controller, not shown in the figure. The controller evaluates the data measured by sens...

The invention relates to an exhaust gas purification system (1) for exhaust gases from an internal combustion engine, in particular from a diesel engine, said system being arranged in an exhaust tract (2) which has a primary exhaust gas treatment system (22) and an inlet line (3) with a metering device (19). In order to achieve higher efficiency in nitrogen conversion, it is proposed that the inlet line (3) together with the metering device (19) be arranged downstream of the exhaust gas treatment system (22) and that the inlet line (3) be divided downstream by the metering device (19) into two catalyst lines (13) which lead the exhaust gas stream from the internal combustion engine in each case to a catalyst element (6, 7), the exhaust gas stream being steerable into the first catalyst element (6) or the second catalyst element (7) by means of a control valve (14).
Description
[0001]The disclosure relates to an exhaust gas purification system for exhaust gases from an internal combustion engine, in particular from a diesel engine, said system being arranged in an exhaust tract which has a primary exhaust gas treatment system and an inlet line with a metering device.[0002]The disclosure relates, furthermore, to a method for nitrogen oxide reduction in an exhaust gas purification system.BACKGROUND AND SUMMARY[0003]US 2008 / 0127635 A1 discloses an exhaust gas purification system with a housing with a dividing element creating a plurality of air. At least one catalytic converter and one particle filter are arranged in the housing. The at least one dividing element is arranged such as to form two chambers which lie one above the other and are connected opposite to the exhaust gas inlet, so that the exhaust gas stream is deflected out of one chamber into the other chamber. An exhaust gas purification apparatus having a reduced longitudinal extent is thereby to b...
