Title: ARRANGEMENT FOR TREATING EXHAUST GASES OF AN INTERNAL COMBUSTION PISTON ENGINE, AN INTERNAL COMBUSTION PISTON ENGINE AND METHOD OF TREATING EXHAUST GAS OF AN INTERNAL COMBUSTION PISTON ENGINE
Abstract:
Invention relates to an arrangement for treating exhaust gases (50) of an internal combustion piston engine (10) comprising a first gas treatment section (52, for example an oxidation catalyst) arranged in a first enclosure (54) and comprising a gas inlet (56) and a gas outlet (58), and a second gas treatment section (62, for example a SCR- unit) arranged in a second enclosure (64) and comprising a gas inlet (66) and a gas outlet (68). The first enclosure (54) is enclosed by the second enclosure (64) and the gas inlet (56) and the gas outlet (58) of the first enclosure (54) open outside the second enclosure (64).
