FIELD: engines and pumps.
SUBSTANCE: catalytically activated filter designed to filtrate solid particles from spent gases (SG) of a diesel engine and having a filtering element and an oxidising-active catalytic coating, and also one more coating catalytically active in the reaction of selective catalytic reduction (SCR-reaction), containing a material that accumulates ammonia, besides, the specified coatings are arranged in the order, in which SG exposed to neutralisation or reduction of toxicity first go through a coating that is catalytically active in the SCR-reaction, and then through the oxidising-active catalytic coating.
EFFECT: simplified and cheaper system of SG neutralisation or toxicity reduction designed to remove nitrogen oxides and solid particles from SG from engines operating at depleted fuel mixtures, and also minimised backpressure of SG.
