FIELD: engines.
SUBSTANCE: invention relates to multistage mixer for use in exhaust systems of internal combustion engines. Multistage mixer is installed in pipe, which is in exhaust system, for mixing flow of exhaust gases and urea in three stages in order to convert it into flow with non-homogeneous structure, which flows both vortex and unsteady manner with characteristics of vortex flow and transverse flow.
EFFECT: invention provides complete splitting of reducing liquid (urea, et cetera) to achieve catalysts, maximum mixing level.
