FIELD: machine building.
SUBSTANCE: control method of operation of waste gas neutralisation system (100) containing at least particulate filter (42) for collection of soot from waste gases of engine (10) and deNOx-catalytic neutraliser (44) to reduce content of nitrogen oxide in waste gas of engine (10). In order to perform regeneration of particulate filter (42), working modes of particulate filter (42) and deNOx-catalytic neutraliser (44) are synchronised to each other when catalytic neutraliser (44) ensures conversion efficiency of nitrogen oxide, which exceeds the specified limit.
EFFECT: providing operation of a particulate filter with higher degree of its filling, as well as with longer intervals between regenerations without any risk of damage to the particulate filter.
