Purifying internal combustion engine exhaust gases, where triple effect, NOx storage and RCS catalyzers are in series and the NOx storage catalyzer can be bypassed when its temperature rises
The installation has a bypass line (5) to allow exhaust gases leaving the triple effect catalyzer to be channeled to the RCS catalyzer, short-circuiting the NOx storage catalyzer. The fraction of exhaust gases leaving the triple effect catalyzer and passing through the bypass line is adjusted as a f...
