FIELD: engines and pumps.
SUBSTANCE: exhaust gas cleaning system in ICE wherein catalytic SOx-neutraliser 13 for catching SOx contained in exhaust gases contains oxygen adsorbing and releasing material 54 that can absorb exhaust gas SO2 and SOx-accumulating material that can store SOx in the form of sulphates. SO2 contained in exhaust gases is chemically adsorbed on said oxygen adsorbing and releasing material 54 without oxidation of the latter. In case temperature of catalytic SOx-neutraliser 13 exceeds initial temperature of adsorbed SO2 transfer then SO2 chemically adsorbed on oxygen adsorbing and releasing material 54 is oxidised and retained in the form of sulphates in SOx-accumulating material (55).
EFFECT: sufficient absorption of catalytic SOx-neutraliser for catching SOx.
