Abstract (en)
[origin: EP3772573A1] An exhaust gas after treatment system (ATS) for a diesel cycle internal combustion engine (E) has a first and a second particulate filter (F1,F2) arranged in series along an exhaust line (EP), which channels exhaust gas from the engine (E) to an external environment; the first particulate filter (F1) is a soot filter, and the second particulate filter (F2) is an ash filter, which is arranged downstream of the soot filter, considering the exhaust gas direction in the exhaust line (EP), and is suitable to be serviced to allow for removal of collected ash.
