FIELD: engines and pumps.SUBSTANCE: invention relates to a device for reduction of toxicity of spent gases (SG) with a component for toxicity reduction. A nozzle (1) for supply of aqueous urea solution as a reducing agent (2) into a system (3) of spent gases (SG) exhaust, having multiple output holes (4, 5), made at the same time with the possibility for each of them to form various drops (6, 7) of the reducing agent (2), differing by their dimensions. Also a device (14) is described to reduce toxicity of SG with a component (15) for reduction of SG toxicity and with at least one appropriate nozzle (1), in which at least two groups (11, 12) of output holes (4, 5) provide for ingress of the reducing agent to different wetted areas (16, 17) on the component (15) for reduction of SG toxicity.EFFECT: provision of varied supply of a fluid and its maximum complete chemical transformation.9 cl, 5 dwg |
