FIELD: chemistry.
SUBSTANCE: system for reducing toxicity of exhaust gases of diesel engines (1), which includes at least one oxidation catalyst (3), one reducing agent sprayer (6) and one reducing catalyst (9), located in the same housing (5) with a first side chamber (15) near the first end (16) thereof and a second side chamber (17) near the second end (18) thereof. The reducing catalyst (9) is located in the first side chamber (15). The oxidation catalyst (3) is located in the radial external annual cavity (11) of the second side chamber (17). The reducing agent sprayer (6) is directed towards the internal channel (19) of the radial external annual cavity (11) of the second side chamber (17). The internal chamber (19) contains a soot particle trap (8) and a path (14) for passage of a stream of the exhaust gas from an exhaust gas inlet (20) to an exhaust gas outlet (21) through the following components: oxidation catalyst (3), reducing agent sprayer (6), internal channel (19) with a soot particle trap (8), reducing catalyst (9).
EFFECT: effective reduction of toxicity of exhaust bases, simple and cheap design.
